I'd like to use terminal for all of my normal git and compiling and running processes (my school has a server that is linked to my repo on bitbucket), but I really don't like terminal-based text editing software such as Emacs and Vim. Is it possible to open and edit files from the terminal using a GUI based text editor? The reason I'm asking is because the terminal is the only way I can access the server files. Thanks in advance!
Aw, but vim is the best! :) Well, you can use nano, which is friendlier. Or, if you insist: if you are using SSH to connect to the server (and the server has an X server running !) then you can look into the ssh -X option to view X windows on your remote machine.
Oh and you could look into scp command as well (behaves almost just like regular cp, but the destination is on another host). That way you could edit on your machine, then copy it via SSH (although you'd want to be careful when copying files directly to the server filesystem)
Edit: Also, if you really don't like using the terminal (why though? (-: ), some file managers allow you to get the same functionality of the previous commands purely via GUI (for example).
You've left out some important information that someone would need to know to answer your questions. The other posters have made some assumptions.
You've mentioned this "terminal", but it's not clear exactly what that is, or how you're getting to it. What kind of computer do you have in front of you? What shell is running in that terminal? Is the shell running on your local computer, or have you remotely connected to a server and running that shell on the remote computer?
Based on what you said, I have a feeling you're making a remote connection to a server, perhaps using ssh. You likely have either a Windows or Mac PC in front of you. In those circumstances, running a GUI editor like Eclipse is possible, but likely not practical. You would have to have Eclipse installed on that remote computer, and you would be displaying the Eclipse window on your local computer using the X11 protocol. That takes a lot of bandwidth.
If my assumptions are correct, my recommendations depend on how long you expect you're going to want to stay familiar with this environment. If you intend to do this sort of work forever, then you should learn vi and Emacs to the best of your ability. As someone who's been using Emacs likely longer than you've been alive, I'd recommend you learn it, but vi is also a critical skill.
UNIXY systems provide open or gopen, depending on your OS, that should get the job done. From the man page:
By default, gopen will open filename with the application currently assigned to the file's extension. But by specifing the -a flag on the command line you can tell gopen to open the file with another application.
This means that you can use it to open files in your preferred editor
with a line like
gopen -a Eclipse file
I have a legacy VB6 system which is installed in C:/Program Files/IronDuke
In the past it has written some files into this directory. I understand that these files are hidden away if the application is installed under Vista or a later OS, but not if they were written under XP or earlier OS.
How can I retrieve a copy of these 'hidden' files when written under Vista or Windows 7 or 8?
You are looking at a feature called UAC Virtualization, this blog posting gives a pretty good rundown on what is happening and where the files are located.
From above article:
For example, if an application attempts to write to C:\Program Files\Contoso\Settings.ini, and the user does not have permissions to write to that directory (the Program Files), the write operation will be redirected to C:\Users\Username\AppData\Local\VirtualStore\Program Files\Contoso\settings.ini. If an application attempts to write to HKEY_LOCAL_MACHINE\Software\Contoso\ in the registry, it will automatically be redirected to HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\Software\Contoso or HKEY_USERS\UserSID_Classes\VirtualStore\Machine\Software\Contoso.
so in your case if you are trying to find the files you need to look in:
C:\Users\Username\AppData\Local\VirtualStore\Program Files\IronDuke\
You cannot write to Program Files under Windows 7 / 8 - system security prevents programs running as regular users from doing so. One option for you is to write these files to the user's profile folder (you'll have to update the VB6 program for this, although the changes should be pretty small if the program is otherwise well-written). This would be your best option since the updated code would work well in the future without more changes.
You amy be able to get the program running using Compatibility Mode but I doubt it - on my Windows 8 system I don't even get 'Windows XP' as a compatibility option anymore. All other options will likely enforce security.
You can try running your program as administrator but I'd only do this if you don't have the source to make the changes - it's poor practice to run programs with all privileges since it opens up the system for attacks.
I have the following boxes:
a) A Windows box with Eclipse CDT,
b) A Linux box, accessible for me only via SSH.
Both the compiler and the hardware required to build and run my project is only on machine B.
I'd like to work "transparently" from a Windows box on that project using Eclipse CDT and be able to build, run and debug the project remotely from within the IDE.
How do I set up that:
The building will work? Any simpler solutions than writing a local makefile which would rsync the project and then call a remote makefile to initiate the actual build? Does Eclipse managed build have a feature for that?
The debugging will work?
Preferably - the Eclipse CDT code indexing will work? Do I have to copy all required header files from machine B to machine A and add them to include path manually?
Try the Remote System Explorer (RSE). It's a set of plug-ins to do exactly what you want.
RSE may already be included in your current Eclipse installation. To check in Eclipse Indigo go to Window > Open Perspective > Other... and choose Remote System Explorer from the Open Perspective dialog to open the RSE perspective.
To create an SSH remote project from the RSE perspective in Eclipse:
Define a new connection and choose SSH Only from the Select Remote System Type screen in the New Connection dialog.
Enter the connection information then choose Finish.
Connect to the new host. (Assumes SSH keys are already setup.)
Once connected, drill down into the host's Sftp Files, choose a folder and select Create Remote Project from the item's context menu. (Wait as the remote project is created.)
If done correctly, there should now be a new remote project accessible from the Project Explorer and other perspectives within eclipse. With the SSH connection set-up correctly passwords can be made an optional part of the normal SSH authentication process. A remote project with Eclipse via SSH is now created.
The very simplest way would be to run Eclipse CDT on the Linux Box and use either X11-Forwarding or remote desktop software such as VNC.
This, of course, is only possible when you Eclipse is present on the Linux box and your network connection to the box is sufficiently fast.
The advantage is that, due to everything being local, you won't have synchronization issues, and you don't get any awkward cross-platform issues.
If you have no eclipse on the box, you could thinking of sharing your linux working directory via SMB (or SSHFS) and access it from your windows machine, but that would require quite some setup.
Both would be better than having two copies, especially when it's cross-platform.
I'm in the same spot myself (or was), FWIW I ended up checking out to a samba share on the Linux host and editing that share locally on the Windows machine with notepad++, then I compiled on the Linux box via PuTTY. (We weren't allowed to update the ten y/o versions of the editors on the Linux host and it didn't have Java, so I gave up on X11 forwarding)
Now... I run modern Linux in a VM on my Windows host, add all the tools I want (e.g. CDT) to the VM and then I checkout and build in a chroot jail that closely resembles the RTE.
It's a clunky solution but I thought I'd throw it in to the mix.
My solution is similar to the SAMBA one except using sshfs. Mount my remote server with sshfs, open my makefile project on the remote machine. Go from there.
It seems I can run a GUI frontend to mercurial this way as well.
Building my remote code is as simple as: ssh address remote_make_command
I am looking for a decent way to debug though. Possibly via gdbserver?
I tried ssh -X but it was unbearably slow.
I also tried RSE, but it didn't even support building the project with a Makefile (I'm being told that this has changed since I posted my answer, but I haven't tried that out)
I read that NX is faster than X11 forwarding, but I couldn't get it to work.
Finally, I found out that my server supports X2Go (the link has install instructions if yours does not). Now I only had to:
download and unpack Eclipse on the server,
install X2Go on my local machine (sudo apt-get install x2goclient on Ubuntu),
configure the connection (host, auto-login with ssh key, choose to run Eclipse).
Everything is just as if I was working on a local machine, including building, debugging, and code indexing. And there are no noticeable lags.
I had the same problem 2 years ago and I solved it in the following way:
1) I build my projects with makefiles, not managed by eclipse
2) I use a SAMBA connection to edit the files inside Eclipse
3) Building the project:
Eclipse calles a "local" make with a makefile which opens a SSH connection
to the Linux Host. On the SSH command line you can give parameters which
are executed on the Linux host. I use for that parameter a makeit.sh shell script
which call the "real" make on the linux host.
The different targets for building you can give also by parameters from
the local makefile --> makeit.sh --> makefile on linux host.
The way I solved that one was:
For windows:
Export the 'workspace' directory from the Linux machine using samba.
Mount it locally in windows.
Run Eclipse, using the mounted 'workspace' directory as the eclipse workspace.
Import the project you want and work on it.
For Linux:
Mount the 'workspace' directory using sshfs
Run Eclipse.
Run Eclipse, using the mounted 'workspace' directory as the eclipse workspace.
Import the project you want and work on it.
In both cases you can either build and run through Eclipse, or build on the remote machine via ssh.
For this case you can use ptp eclipse https://eclipse.org/ptp/ for source browsing and building.
You can use this pluging to debug your application

How to edit in Eclipse locally, but use a git-based script I wrote (sync_git_repo_from_pc1_to_pc2.sh) to synchronize and build remotely
The script I wrote to do this is sync_git_repo_from_pc1_to_pc2.sh.
Readme: README_git-sync_repo_from_pc1_to_pc2.md
Update: see also this alternative/competitor: GitSync:
How to use Sublime over SSH
https://github.com/jachin/GitSync
This answer currently only applies to using two Linux computers [or maybe works on Mac too?--untested on Mac] (syncing from one to the other) because I wrote this synchronization script in bash. It is simply a wrapper around git, however, so feel free to take it and convert it into a cross-platform Python solution or something if you wish
This doesn't directly answer the OP's question, but it is so close I guarantee it will answer many other peoples' question who land on this page (mine included, actually, as I came here first before writing my own solution), so I'm posting it here anyway.
I want to:
develop code using a powerful IDE like Eclipse on a light-weight Linux computer, then
build that code via ssh on a different, more powerful Linux computer (from the command-line, NOT from inside Eclipse)
Let's call the first computer where I write the code "PC1" (Personal Computer 1), and the 2nd computer where I build the code "PC2". I need a tool to easily synchronize from PC1 to PC2. I tried rsync, but it was insanely slow for large repos and took tons of bandwidth and data.
So, how do I do it? What workflow should I use? If you have this question too, here's the workflow that I decided upon. I wrote a bash script to automate the process by using git to automatically push changes from PC1 to PC2 via a remote repository, such as github. So far it works very well and I'm very pleased with it. It is far far far faster than rsync, more trustworthy in my opinion because each PC maintains a functional git repo, and uses far less bandwidth to do the whole sync, so it's easily doable over a cell phone hot spot without using tons of your data.
Setup:
Install the script on PC1 (this solution assumes ~/bin is in your $PATH):
git clone https://github.com/ElectricRCAircraftGuy/eRCaGuy_dotfiles.git
cd eRCaGuy_dotfiles/useful_scripts
mkdir -p ~/bin
ln -s "${PWD}/sync_git_repo_from_pc1_to_pc2.sh" ~/bin/sync_git_repo_from_pc1_to_pc2
cd ..
cp -i .sync_git_repo ~/.sync_git_repo
Now edit the "~/.sync_git_repo" file you just copied above, and update its parameters to fit your case. Here are the parameters it contains:
# The git repo root directory on PC2 where you are syncing your files TO; this dir must *already exist*
# and you must have *already `git clone`d* a copy of your git repo into it!
# - Do NOT use variables such as `$HOME`. Be explicit instead. This is because the variable expansion will
# happen on the local machine when what we need is the variable expansion from the remote machine. Being
# explicit instead just avoids this problem.
PC2_GIT_REPO_TARGET_DIR="/home/gabriel/dev/eRCaGuy_dotfiles" # explicitly type this out; don't use variables
PC2_SSH_USERNAME="my_username" # explicitly type this out; don't use variables
PC2_SSH_HOST="my_hostname" # explicitly type this out; don't use variables
Git clone your repo you want to sync on both PC1 and PC2.
Ensure your ssh keys are all set up to be able to push and pull to the remote repo from both PC1 and PC2. Here's some helpful links:
https://help.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh
https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
Ensure your ssh keys are all set up to ssh from PC1 to PC2.
Now cd into any directory within the git repo on PC1, and run:
sync_git_repo_from_pc1_to_pc2
That's it! About 30 seconds later everything will be magically synced from PC1 to PC2, and it will be printing output the whole time to tell you what it's doing and where it's doing it on your disk and on which computer. It's safe too, because it doesn't overwrite or delete anything that is uncommitted. It backs it up first instead! Read more below for how that works.
Here's the process this script uses (ie: what it's actually doing)
From PC1: It checks to see if any uncommitted changes are on PC1. If so, it commits them to a temporary commit on the current branch. It then force pushes them to a remote SYNC branch. Then it uncommits its temporary commit it just did on the local branch, then it puts the local git repo back to exactly how it was by staging any files that were previously staged at the time you called the script. Next, it rsyncs a copy of the script over to PC2, and does an ssh call to tell PC2 to run the script with a special option to just do PC2 stuff.
Here's what PC2 does: it cds into the repo, and checks to see if any local uncommitted changes exist. If so, it creates a new backup branch forked off of the current branch (sample name: my_branch_SYNC_BAK_20200220-0028hrs-15sec <-- notice that's YYYYMMDD-HHMMhrs--SSsec), and commits any uncommitted changes to that branch with a commit message such as DO BACKUP OF ALL UNCOMMITTED CHANGES ON PC2 (TARGET PC/BUILD MACHINE). Now, it checks out the SYNC branch, pulling it from the remote repository if it is not already on the local machine. Then, it fetches the latest changes on the remote repository, and does a hard reset to force the local SYNC repository to match the remote SYNC repository. You might call this a "hard pull". It is safe, however, because we already backed up any uncommitted changes we had locally on PC2, so nothing is lost!
That's it! You now have produced a perfect copy from PC1 to PC2 without even having to ensure clean working directories, as the script handled all of the automatic committing and stuff for you! It is fast and works very well on huge repositories. Now you have an easy mechanism to use any IDE of your choice on one machine while building or testing on another machine, easily, over a wifi hot spot from your cell phone if needed, even if the repository is dozens of gigabytes and you are time and resource-constrained.

How to do a "hard pull", as I call it: How do I force "git pull" to overwrite local files?

git repository sync between computers, when moving around?
I would like to know if I can use g++ to compile C++ source files stored on an FTP server? Can this be done?
Note: The FTP server is within the local network
You can't execute commands over FTP, nor can you operate directly on files stored on an FTP server unless you have mapped the FTP server to a filesystem. How to do the latter depends on your operating system.
Since you said g++, I assume Linux, so look into FTPFS.
No, this is not possible. Ftp doesn't allow you to execute programs on the server, it is just used to transfer files. To execute programs (like the compiler) you need some different kind of access to the server, like for example with Ssh.
If you are using a Linux system (and probably any *nix or BSD flavout as well) then yes it is possible if the ftp-server is mounted as a filesystem on your machine, like Tyler McHenry wrote.
It is however not neccessary to "look into FTPFS" if you are using any recent Gnome-based distro. In Ubuntu (9.04) I can do "Places"->"Connect to server" and choose FTP. Then, when the folder is opened in Nautilus you can find the mounted directory in ~/.gvfs/ and then you should be able to compile it without any trouble at all.
I would be very surprised if KDE did not have the same feature, but the directory will be mounted somewhere else.
Does the FTP server have a public website that works with scripting languages, such as PHP? If so, you could upload your source code, edit a PHP file that calls system and compile your code.
In general this probably isn't a good idea: It's a slow, manual process & could be subject to security problems if the PHP script lets you edit the compilation command.
I am developing on a Windows machine using Eclipse in C code.
All the files are physically located on a Linux server.
I am using Eclipse only for editing and code browsing.
When I want to compile, I open a terminal and telnet to the Linux server from which I call a file that sets up few variables and eventually invoke a "make" command.
The server is pretty busy.. I would then like to be able to compile locally [and then just ftp these executable files back to the Linux machine so that I can execute them.. unless Eclipse can do that on its own :) ].... any idea how can that be done? I am not well versed in Eclipse or OS usage.... so if you could answer and explain what I should do.. I would really appreciate...
I changed the Build Command under Project Properties menu by just calling the script file on the server I usually invoke to compile... That looked fairly simple.. well... that was too good to be true... and of course.. it didn't work! I am getting this error if I use the default "make" (Cannot run program "make": Launching failed).... while getting (Cannot run program "T:\compile": Launching failed) if I try to invoke my script file that I use to compile...
thanks,
You should take a look at running a crosstool-ng setup on your windows box inside cygwin. And then have eclipse use that compiler. This will allow you to develop for your target Linux platform easily.
Here's some slides
It sounds like you're developing for a desktop/server platform, so you'll have to make sure you set up your crosstool-ng with the same versions of standard libs as your server has (libc, libstdc++, etc). You also want to make sure your crosstool-ng has the same version of gcc as the target as well.
If you don't want to mess with getting all that setup, you could always install Linux as a virtual machine on your windows box and work inside there.
