What I want is to store the output of a git command (such as git status) inside a variable in a shell script. When I say output, I am talking about the text returned in the terminal on execution of a command, for example: on doing a git status outside my repo:
fatal: Not a git repository (or any of the parent directories): .git I tried this:
var=$(git status) But 'var' did not store anything.

To store the output of a command in a variable, you can use the shell command substitution feature in the forms below: variable_name=$(command) variable_name=$(command [option ...] arg1 arg2 ...) OR variable_name='command' variable_name='command [option ...]
Git clone Git clone is a command for downloading existing source code from a remote repository (like Github, for example). In other words, Git clone basically makes an identical copy of the latest version of a project in a repository and saves it to your computer.
We just need to pass another parameter capture=true with local to store the output of a command in a variable. substring = "up-to-date" msg = local ("git pull", capture=true) if substring in msg: "do something" else: "do something else" If you are using a version of Python older than 2.6 you can use popen, like in the example below.
text processing - Save the output of a command to a variable - Unix & Linux Stack Exchange The command mid3v2 -l someFile.mp3 gives the following output for a file with name someFile.mp3 in mp3-format: IDv2 tag info for someFile.mp3 APIC=cover front, (image/jpg, 52016 bytes) TALB= Stack Exchange Network
The first step is to understand that the output of a command could be received by other commands via a pipe, or, could be captured in a variable: cmd | next command ... etc var=$(cmd)
To pipe the output of a command to tee , printing to to your screen and saving it to a file, but appending it to the end of the file: This will append the output to the end of the file, just like the >> operator.
You can use:
var=$(git status 2>&1) i.e. redirect stderr to stdout and then capture the output.
Otherwise when for error messages are written on stderr and your command: var=$(git status) is only capturing stdout.
