Some git commands produce output in the terminal, for example,
git log shows the details of previous commits. If you’re writing a bash script to automate some build process then you might need to save the output from one of these git commands.
Save git command line output in a variable
To execute git commands in bash you can use
env -i and then the
git <command>, for example:
1.env -i git log
To capture the output from that command, wrap the full command
env -i git log in parenthesis:
1.$(env -i git log)
Finally, set that output to a variable:
1.GIT_LOG= $(env -i git log)
Save last git hash
In a recent project, I had to create a bash variable to store the output of the most recent commit hash. It’s pretty useful if you need to create custom, unique, version names.
1.LAST_GIT_HASH= $(env - i git log --pretty=format:'%h' -n 1)
