Here's what I would do.

  1. Write a script (e.g. prefix_commit.sh) that looks like this:

    #!/bin/bash
git commit -m User:"$1"

    Note:

    • Using git commit -m "User:$1" will also work here.

  1. Make the script executable (you only need to do this once):

    $ chmod +x ./prefix_commit.sh

  2. Call the script from the command line and pass your commit message like so:

    $ ./prefix_commit.sh 'Sample commit message'

    Note:

    • Be sure to use single quotes around your commit message if you plan on writing messages with multiple words.

Passing arguments to a bash script

  • Arguments can be received in a bash script or function like so: 

    $1 # first argument
$2 # second argument
$3 # third argument

### $4, $5, $6, $7 ... etc

  • So let's say I have a script that's called echo_my_args.sh that echoes out three arguments:

    #!/bin/bash
echo $1
echo $2
echo $3

  • I can pass three arguments to the script and see them echoed out:

    $ ./echo_my_args.sh 'my first arg' 'my second arg' 'my third arg'
my first arg
my second arg
my third arg

  • Note here again that the argument must use single quotes if it has multiple words. There is no need for single quotes if you pass a single word argument:

    $ ./echo_my_args.sh first second third
first
second
third

  • Here's some more information about how to pass arguments to a bash script.
