Supplying a password to Git in a Bash script

Question

From a Bash script I would like to supply a password. I have tried the following:

echo 'mypass' | git pull

git pull < 'mypass'

git pull < echo 'mypass'

None seem to work.

Answer 1

1. Create file git_password.sh with content:

   #!/bin/sh
   exec echo "$GIT_PASSWORD"
   

2. Assign your password to the GIT_PASSWORD environment variable

   $ GIT_PASSWORD=your_password
   

3. Execute git command with GIT_ASKPASS environment variable. It will force password prompt and execute git_password.sh as callback:

   $ GIT_ASKPASS=./git_password.sh git clone $REPO
