prepare-commit-msg
#!/bin/sh
#
# An example hook script to prepare the commit log message.
# Called by "git commit" with the name of the file that has the
# commit message, followed by the description of the commit
# message's source. The hook's purpose is to edit the commit
# message file. If the hook fails with a non-zero status,
# the commit is aborted.
#If your current branch matches the pattern f/TICKET-ID1234 or f/TICKET-ID1234-some-description
# this script will append [TICKET-ID1234] to your commit message
branch=$(git symbolic-ref -q --short HEAD)
ticket=$(echo $branch | sed -n 's/^f\/\([A-Z]\+-[0-9]\+\)-\?.*/\1/p')
if [ -n "$ticket" ]; then
sed "1s/^/[$ticket] /" $1 > $1.new
mv $1.new $1

I don't think the sed script is working on a mac

23:47 ~/tp/cenx/rdops (f/RD-1012)$ branch=$(git symbolic-ref -q --short HEAD)
23:47 ~/tp/cenx/rdops (f/RD-1012)$ ticket=$(echo $branch | sed -n 's/^f\/\([A-Z]\+-[0-9]\+\)-\?.*/\1/p')
23:48 ~/tp/cenx/rdops (f/RD-1012)$ echo $branch
f/RD-1012
23:48 ~/tp/cenx/rdops (f/RD-1012)$ echo $ticket

23:48 ~/tp/cenx/rdops (f/RD-1012)$

Looks like on a mac, the "+" is the problem, so on a mac try

branch=$(git symbolic-ref -q --short HEAD)
ticket=$(echo $branch | sed -n 's/\f\/\([A-Z][A-Z]*-\d*\)/\1/p')

if [ -n "$ticket" ]; then
    sed "1s/^/[$ticket] /" $1 > $1.new
    mv $1.new $1
fi
