# An example hook script to check the commit log message. | |
# Called by "git commit" with one argument, the name of the file | |
# that has the commit message. The hook should exit with non-zero | |
# status after issuing an appropriate message if it wants to stop the | |
# commit. The hook is allowed to edit the commit message file. | |
# | |
# To enable this hook, rename this file to "commit-msg". | |
# Uncomment the below to add a Signed-off-by line to the message. | |
# Doing this in a hook is a bad idea in general, but the prepare-commit-msg | |
# hook is more suited to it. | |

SOB=$(git var GIT_AUTHOR_IDENT | sed -n 's/^\(.*>\).*$/Signed-off-by: \1/p') | |

# This example catches duplicate Signed-off-by lines. | |
test "" = "$(grep '^Signed-off-by: ' "$1" | | |
