A script I need to run uses tempfile, but I don't have that on my Mac. I do use Macports. How can I find out which Macports package I need to install to get tempfile?
tempfile is a shell command used in scripting. It's an ELF binary on my Linux box and belongs to the debianutils package, as shown by dpkg -S /bin/tempfile. I Installed the Macports debianutils package and now have tempfile.
Just wondering how I'll figure this out if I don't have a Linux box handy...
Is tempfile a Python library? If so, you should be able to install it with pip if you have it.
On another note, you should probably switch to Homebrew as your package manager.

I was watching this, and, as you can see, the first command I am told to put in is:
sudo apt-get install python-setuptools
When I do this, it outputs:
sudo: apt-get: command not found
I have no idea why this is the case.
How can I resolve this so I am following the tutorial correctly?
Mac OS X doesn't have apt-get. There is a package manager called Homebrew that is used instead.
This command would be:
brew install python
Use Homebrew to install packages that you would otherwise use apt-get for.
The page I linked to has an up-to-date way of installing homebrew, but at present, you can install Homebrew as follows:
Type the following in your Mac OS X terminal:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
After that, usage of Homebrew is brew install <package>.
One of the prerequisites for Homebrew are the XCode command line tools.
Install XCode from the App Store.
Follow the directions in this Stack Overflow answer to install the XCode Command Line Tools.
Background
A package manager (like apt-get or brew) just gives your system an easy and automated way to install packages or libraries. Different systems use different programs. apt and its derivatives are used on Debian based linux systems. Red Hat-ish Linux systems use rpm (or at least they did many, many, years ago). yum is also a package manager for RedHat based systems.
Alpine based systems use apk.
Warning
As of 25 April 2016, homebrew opts the user in to sending analytics by default. This can be opted out of in two ways:
Setting an environment variable:
Open your favorite environment variable editor.
Set the following: HOMEBREW_NO_ANALYTICS=1 in whereever you keep your environment variables (typically something like ~/.bash_profile)
Close the file, and either restart the terminal or source ~/.bash_profile.
Running the following command:
brew analytics off
the analytics status can then be checked with the command:
brew analytics
As Homebrew is my favorite for macOS although it is possible to have apt-get on macOS using Fink.
MacPorts is another package manager for OS X:.
Installation instructions are at The MacPorts Project -- Download & Installation after which one issues sudo port install pythonXX, where XX is 27 or 35.
Conda can also be used as package manager. It can be installed from Anaconda.
Alternatively, a free minimal installer is Miniconda.
apt-get command is only available on Debian or Debian-based Linux distributions (such as Ubuntu, Linux Mint, Kali). It is not accessible on macOS. Alternatively, you can use package managers like Homebrew, MacPorts, and Nix. You can find equivalent commands for each as follows
brew install package_name
sudo port install package_name
nix-env -i package_name
Before installing above package managers, you need to install XCode first. Follow the operation instructions from this guide How to Fix "sudo apt-get command not found" Error on Mac Terminal.
Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...
For example,
curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz
I'm new to ubuntu and i'm currently using it on windows 7 with vmware workstation.
I need to access the CPU usage with a C program on terminal, so i thought of using glibtop_get_cpu() function on glibtop library. I just wrote #include <glibtop.h> in my code and compiled it with "gcc" on terminal, and it said
fatal error: glibtop.h: No such file or directory
compilation terminated.
I tried to install the library using this:
sudo apt-get install liblib2.0-dev
but the terminal said:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libglib2.0-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
However the following packages replace it:
libglib2.0-0 libglib2.0-bin
E: Package 'libglib2.0-dev' has no installation candidate
any ideas about this?
You should install libgtop2-dev (sudo apt-get install libgtop2-dev).
I am new in json and I don't know how to use but I found compare to XML json is better so, I am learning json in C programming in Ubuntu 14.0LTS.
I followed https://linuxprograms.wordpress.com/2010/05/20/install-json-c-in-linux/.
In this link, I installed libjson0 with the help of first command but when I installed libjson – debug symbols package with the help of second command which is mentioned in link then showing "E: Unable to locate package libjson0-dbg".
Also I gone through https://github.com/json-c/json-c. After cloning moved to json-c directory, in json-c directory I did sh autogen.sh then showing "autogen.sh: 2: autogen.sh: autoreconf: not found".
Why autoreconf is not works ? When I installed CppUTest and other stuffs then it works.
I also install build-essential which found in google for above problems but it can't works for me.
How can I installed cjson in a proper manner and how to use with the C-programms.
Try below commands:
$ sudo apt-get install libjson-glib-1.0-0 libjson-glib-1.0-0-dev
If you want to debug your programs and see the various steps of serializing/deserializing you can also install the libjson-glib – debug symbols package
$ sudo apt-get install libjson-glib-1.0-0-dbg
For documentation related to json-glib, you must install the following package
$ sudo apt-get install libjson-glib-1.0-0-doc
This documentation will then be available in file:///usr/share/gtk-doc/html/json-glib/index.html
Maybe your problem is related with the path.
The library is installed correctlly but you have tot tell the system where. Here a post on how to do it in Ubuntu How to set the environmental variable LD_LIBRARY_PATH in linux
I am a begineer trying to get code in C. I am working on a Mac and using xcode. My only past experience has been with java using eclipse and everything was pretty straight forward. I have almost no experience with terminal.
I am required to learn a bit of C for a project I will be working on and the learning of syntax is coming along okay, but I am at a point where I need to include some libraries in my c program. Specifically I am attempting to make plots with gnuplots.
I have downloaded gnuplot-4.6.3 from their repository and I do not even know how to install the files. I have been looking around and have tried using terminal to use the ./configure command when I am in the gnuplot-4.6.3 directory. But I really don't know what I am doing so I don't even know where to go next or what to do next.
Sorry if this is so trivial, I honestly just have never done this before and I cannot find a good tutorial on what to do.
Thanks for any help you can offer.
I would recommend using MacPorts for installing third-party tools and libraries. It knows the dependencies required and will install them as part of the installation.
Download it from macports.org.
Install it, and allow it to modify your ~/.profile so that /opt/local/bin is in your $PATH (any issue then just do export PATH=/opt/local/bin:$PATH from the command line).
sudo port selfupdate
sudo port install gnuplot
Now that will install the library into /opt/local/lib with the include files in /opt/local/include, so now just add that library to your Xcode project. Select the target and in the Build Phases tab open up the Link Binary With Libraries and press the + button and select Add Other. Now find /opt/local/lib/libgnuplot.a (I am assuming that's what it's called; I don't have it installed my self):
Now add /opt/local/include to your Header Search Paths so the compiler can find the gnuplot header files. Select the target and in Build Setting type in "header search" in the search box. Now double-click on the Header Search Path in the target column (or the project column to the right) and add /opt/local/include:
It's fine! You're learning then! Keep up! When I hit this kind of problem you may want to learn about the basis for linux gcc/g++ compilation and linking processes. Then you should learn Cmake and Automake, which are basically packages to configure projects before compiling building.
A typical (good) project in Unix systems build with commands
./configure
make
sudo make install
or
cmake CMakelists.txt
make all
sudo make install
That's what you need to do after downloading a source tarball online to install unix programs.
Now since you are using Mac, there are so-called package installers, one which is macports and homebrew. I personally suggest homebrew than macports here (I've tried both, although macports still outnumber homebrew with the number of repos, homebrew has the newest support, especially when upgrading to a new OS). So to install homebrew you can do
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Execute that in your terminal (see http://brew.sh/) for more information.
Then you could simply install GNUplot by
brew install gnuplot
I am on an up-to-date Ubuntu 12.04 system. I have unixodbc (v2.2.14 from ubuntu repos), MySQL and its relevant drivers installed. Also connected to a valid DSN. Verified by issuing isql DBName UName passwd.
I am trying to compile a C application that interacts with the database using ODBC. Almost everywhere I searched seemed to indicate that I should have "sql.h" installed somewhere. A find / -iname sql.h -print showed I don't have it.
So my question is: where is it? Did something go wrong with the install (no errors were reported though)? And what steps do you recommend? Reinstallation? Compilation from source code (the latest version?)?
You need to install the unixodbc-dev package to get the development header files.
sudo apt-get install unixodbc-dev
The -dev packages contain the require header files required to compile and build programs using these headers to make calls to the library. The library files themselves would be part of the regular package i.e. unixodbc in your case.
If you want to know which package provides a certain file, you could use apt-file:
sudo apt-file update
sudo apt-file find sql.h
