Where is the sqlite> tag on Git Bash so I know when I'm accessing sqlite? There's also no version text too.
When I enter .quit into git bash it quits out of sqlite (showing that I am accessing sqlite) but there's no tag like there is in cmd or powershell
On the cmd terminal when I access Sqlite3 it clearly shows sqlite> so I know when I'm in it.
How do I get the sqlite> tag on Git Bash?
Things like these make use of interactive terminals, and MinTTY (the underlying emulator used to run Git Bash) doesn't get along well with them. You need to prefix every such command with winpty. In this case: winpty sqlite3.

this is my first ever question. Okay..
Relevant to this problem :
I am using cmder
I am new to the terminal
I am using a windows PC
I'm following a tutorial on how to install mongoDB locally, after running the setup my first problem came when
On the terminal The tutor did
Cd ~
To go to the home directory but when I tried the same command on the cmder I received
The system cannot find the path specified
So I navigated manually using "cd.. " to
c:\Users\<username>
Which I think is the home directory，I created the ".bash_profile" file and saved the following commands in it
alias mongod = "/c/program\ files/MongoDB/server/4.4/bin/mongod.exe"
alias mongo = "/c/program\ files/MongoDB/server/4.4/bin/mongo.exe"
But when I run the mongod or test if it's installed completely it returns
'mongod' is not recognized as an internal or external command, operable program or batch file
Please I don't know my way round the terminal that much, please be detailed with answers
Thanks in advance
alias mongod="/c/Program\ Files/MongoDB/server/4.4/bin/mongod.exe"
alias mongo="/c/Program\ Files/MongoDB/server/4.4/bin/mongo.exe"
Removing spaces and making uppercase the first letters of program files worked for me.
cmder doesn't interpret shell arguments like ~, which means tilde won't work in paths. Also, be aware the way you spelled Cd. It can cause an error in other command line tools (case sensitive ones like Git Bash).
1 - If you're using cmder/cmd.
Use doskey to create an alias/shortcut:
Create C:\bat\macros.txt to store your macros/aliases and paste:
cdhome=cd /d %HOMEDRIVE%%HOMEPATH%
mongo="C:\Program Files\MongoDB\Server\4.4\bin\mongo.exe" $*
mongod="C:\Program Files\MongoDB\Server\4.4\bin\mongod.exe" $*
Rename everything you want but %HOMEDRIVE%%HOMEPATH%. $* at the end means the command accepts arguments, like mongo --version.
Keep in mind that .bash_profile isn't related with cmder/cmd, that's why your mongo commands are there too.
Then Windows + R and type regedit.
Go to HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\
Right-click and add a new "String Value". Name it Autorun.
Right-click it and modify the value data to DOSKEY /MACROFILE="C:\bat\macros.txt"
2 - If you're using Git Bash, Hyper terminal, etc.
On .bash_profile, just remove the spaces around the equals sign. Like:
alias mongod="/c/program\ files/MongoDB/server/4.4/bin/mongod.exe"
alias mongo="/c/program\ files/MongoDB/server/4.4/bin/mongo.exe"
or on Windows, you can just go to System properties/Advanced/Environment Variables. Under System variables, find the Variable called Path. Click edit, then New and paste in the path of the mongoDB bin folder:
C:\Program Files\MongoDB\Server\4.4\bin
keep in mind to write version your mongodb correctly in path, now its 4.4
By adding a path to the path variable you can access the .exe files from that path no matter where you are in the directory. It serves the same purpose as the .bash_profile file. Doing it this way allows this to work with windows cmd prompt or cmder as well. Upon launching, the bash emulator gets the environment variables from Windows anyways.
After adding the mongoDB path, open cmd prompt or any bash emulator and type in mongo. It will load up mongo.exe regardless of your current working directory.
Be Specific about the spaces after alias.
alias alias_name ="path.."
I faced alot of issues despite so many answers so this worked for me.
1.First install git and hyper terminal
2.Click the '~' sign to enter the home directory and then make a new file ".bash_profile"
Enter the command "vim .bash_profile"
Now enter 'i' key to enter the insert mode
Copy paste the exact command below:
alias mongod="C:/Program\ Files/MongoDB/Server/5.0/bin/mongod.exe"
alias mongo="C:/Program\ Files/MongoDB/Server/5.0/bin/mongo.exe"
(make sure that you use forward slash '/' for path and "\" backward slash to indicate space between program and files)
enter esc
write the command ':wq!' and click enter
restart hyper terminal and check the installation by running the command 'mongo --version'
Use git bash instead of CMDER
OR
Try to install mongosh from this link:
[1]: https://www.mongodb.com/try/download/shell?jmp=docs
And after setup go to hyper terminal and write mongosh => to connect to MongoDB on port 27017 and then you will see => test>
now you are ready to use the Database and you can write help to see Shell Help.
Check if mongo.exe or mongod.exe files are exist. In my case the bin directory had mongos.exe instead of mongo.exe.
I am trying to run the dmtx project from Git (link: https://github.com/dmtx/dmtx-utils) in Netbeans. I have configured the Project Properties in NetBeans and the project is building correctly.
When I run a particular C file (dmtxwrite.c) through bash it gives the correct output. As mentioned in the README, the correct way to run it in Bash is:
$ echo -n 123456 | dmtxwrite > image.png.
Now my question is how can I do the same using NetBeans?
Till now I only found answers related to passing command line arguments. However, that does not work.
how can I do the same using NetBeans?
Select your C project in the Projects panel.
Right-click it to open the context menu, then select Properties > Run > Run Command.
Enter your command to be run in the Run Command field.
This is the Help for Run Command in NetBeans 8.2:
Enter a command to be executed when you run the project. The IDE runs the command as /bin/sh -c "run-command" which enables you to use any shell syntax including redirection and pipes. Type the command in the Run Command field the same way you would run it from the command line. For example, you could type my-script -opt1 -opt2 to run a script and specify two options, or mycommand > output.log to run your command and send the output to a logfile. The Run Command list maintains history of previous entries so you can go back to the default value or select among several different commands you have entered.
I try run command mongo in linux console without entering into mongo shell.
To do it:
[root#router-mongos ~]# mongo --eval " printjson(show databases)"
But not run, this is the output:
MongoDB shell version: 2.6.10
connecting to: test
2015-06-10T18:33:39.834+0200 SyntaxError: Unexpected identifier
Though if you are uses:
[root#router-mongos ~]# mongo maria --eval " printjson (db.stats())"
o
mongo --eval " printjson(db.adminCommand('listDatabases'))"
Yes, the output is the same if you run it in shell.
Has anyone ever used this? can we help me? Thanks.
From the Mongo Shell documentation:
You cannot use any shell helper (e.g. use , show dbs, etc.) inside the JavaScript file because they are not valid JavaScript.
Following that, there is a table showing the JavaScript equivalents of the various shell helpers. From that, show dbs and show databases should be replaced by db.adminCommand('listDatabases') in your Mongo shell scripts.
I am trying to backup a db of postgresql and I want to use pg_dump command.
I tried :
psql -U postgres
postgres-# pg_dump test > backup.sql
But I don't know where the output file goes.
Any help will be appreciated
I'm late to this party, but I feel that none of the answers are really correct. Most seem to imply that pg_dump writes a file somewhere. It doesn't. You are sending the output to a file, and you told the shell where to write that file.
In your example pg_dump test > backup.sql, which uses the plain or SQL format, the pg_dump command does not store any file anywhere. It just sends the output to STDOUT, which is usually your screen, and it's done.
But in your command, you also told your shell (Terminal, Command prompt, whatever) to redirect STDOUT to a file. This has nothing to do with pg_dump but is a standard feature of shells like Bash or cmd.exe.
You used > to redirect STDOUT to a file instead of the screen. And you gave the file name: "backup.sql". Since you didn't specify any path, the file will be in your current directory. This is probably your home directory, unless you have done a cd ... into some other directory.
In the particular case of pg_dump, you could also have used an alternative to the > /path/to/some_file shell redirection, by using the -f some_file option:
-f file --file=file
Send output to the specified file. This parameter can be omitted for file based output formats,
in which case the standard output is used.
So your command could have been pg_dump test -f backup.sql, asking pg_dump to write directly to that file.
But in any case, you give the file name, and if you don't specify a path, the file is created in your current directory. If your prompt doesn't already display your current directory, you can have it shown with the pwd command on Unix, and cd in Windows.
Go to command prompt and directory postgresql\9.3\bin.
Example
.
..
c:\Program files\postgresql\9.3\bin> pg_dump -h localhost -p 5432 -U postgres test > D:\backup.sql
...
After above command enter User "postgres" password and check D:\ drive for backup.sql file
In my situation (PostgreSQL 9.1.21, Centos 6.7), the command
runuser -l postgres -c 'pg_dump my_database > my_database.sql'
saved the file here:
/var/lib/pgsql/my_database.sql
Not sure if that is true for other Linux dists, CentOS and/or pgl versions. According to the answer post by the asker of this question, this is true, but other users said the backup file was in the current directory (a situation different of most people reading this thread, for obvious reasons). Well, I hope this can help other users with the same problem.
P.s.: if that's not the path for your situation, you can try (in Linux) to find it using the below command (as stated by #Bohemian in the comments of this question), but this can take a while:
find / -name 'my_database.sql'
EDIT: I tried to run the analogous command in Ubuntu 12.04 (it works on Ubuntu 18.04):
sudo -u postgres pg_dump my_database > my_database.sql
And in this case the file was saved in the current directory where I ran the command! So both cases can happen in Linux, depending of the specific dist you are working
For Linux default dump path is:
/var/lib/postgresql/
If you are not specifying fully qualified paths, like:
pg_dump your_db_name > dbdump
then in Windows it stores dumps in current user's home directory. I.e.:
C:\Users\username
If you use linux (except centos)
sudo su - postgres
pg_dump your_db_name > your_db_name.sql
cd /var/lib/postgresql
ls -l
Here your'll see your_db_name.sql file
In pgadmin 4 for a Mac, assuming dump is successful you can click on "More Details" you will see a box that says "Running command:" in that box you will see /Applications/pgAdmin 4.app/Contents/SharedSupport/pg_dump --file "path/to/file" where path to file is the destination of storage.
After doing
psql -U postgres
Using the command
\! pg_dump -U postgres humaine > C:\Users\saivi\OneDrive\Desktop\humaine_backup1.sql
The output file would go where the path at the right is specified
In the server (Ubundu/Centos) the path of backup file will be
/var/lib/pgadmin/storage/
Below is the OS specification.
NAME="Ubuntu"
VERSION="20.04 LTS (Focal Fossa)"
I am using following command to take the backup of postgresql database.
pg_dump -U postgres -Fc <db_name> > /var/lib/postgresql/backup-20230123.dump
If storage file path has been provided explicitly, in that case, the database dump will be generated to that place only.
For windows, provide folder path where you want to download the dump.
I have been using the cake command on my linux server for 2 years. but now im trying to move to a new server and some how the cake command gives back the error: No such file or directory
even if i give the entire path to the cake command file chmod 777 it stil wont work.
I found the solution: All I had to do is use the program dos2unix the cake file for CakePHP 2.4.2 has wrong endings when you download it with Ubuntu 13.10
I used the following command:
sudo dos2unix /path/to/cake/lib/Cake/Console/cake
I also have this problem on some servers and never figured out why this happened. I suspect the so called "shebang" might not be set correctly for every Linux distribution (e.g. if the cake script stars with #!/usr/bin/env bash, but you don't use bash on your server or your distribution doesn't have the env binary in that path, it might fail on that. This is just a theory though, as I said I never really figured it out, nor did I invest much time in investigating.
Although, what I always use as a fallback is simply calling the cake.php script (from the app folder) instead, like:
php Console/cake.php -app `pwd` bake
That never lets me down. The -app pwd bit is to tell the shell that your current directory is your app directory, so the shell can find all your files.
The REAL solution to this is to change the End-of-Line (EOL) characters to Unix format, instead of MsDos. So I guess this error will only occur if you worked in Windows.
Anyway, teh mighty
SOLUTION:
(1) Open app/Console/cake file using any text editor that allows changing of EOL characters e.g. NotePad++.
(2) In NotePad++ click:
Edit -> EOL Conversion -> Convert to Unix format
(3) Save the file and upload it to the server. Now if you navigate to the CakePHP app directory using command like:
cd /usr/share/nginx/html/cakeproject/app
...you should be able to run Console/cake without any problems and see standard output (basically help commands).
Hope this helped you!
I encountered the same problem as well, but the top answer reminded me of a similar problem I faced before: https://stackoverflow.com/a/5514351/1097483
Basically, instead of using dos2unix or installing it, you can open the file in vim, do
:set fileformat=unix
And save it.
In some versions it's possible to install cake using sudo apt-get install cakephp-scripts.
After instalation, you coud access bake anywere simple by typing bake
