Sh script to prepend bug description and append signed-off-by to a series of commits by a single author.

commit-wrapper.sh

# Written by Jonathan Balsano <jrbalsano@gmail.com>
# Example usage: ./commit-wrapper.sh "Jonathan Balsano" "jrbalsano@gmail.com" master topic_branch "Bug 999 - Unwrapped Commits"

if [ -z "$1" ] || [ -z "$2" ] || [ -z "$3" ] || [ -z "$4" ] || [ -z "$5" ]; then
  echo "usage: ./commit-wrapper.sh <author> <cla_email> <excl_oldest> <newest> <prepend_bug>"
  exit 1
fi

export AUTHOR="$1"
export CLA_EMAIL="$2"
export EXCL_OLDEST="$3"
export NEWEST="$4"
export BUG="$5"

git filter-branch -f --msg-filter '
    if [ "$GIT_AUTHOR_NAME" = "$AUTHOR" ]; then
      echo "$BUG" && echo && cat && echo && echo "Signed-off-by: $AUTHOR <$CLA_EMAIL>"
    else
      cat
    fi' \
    $EXCL_OLDEST...$NEWEST

A good first attempt. But that will put the same Signed-off-by on each commit, but you need a different signed-off-by depending on who the read author for the commit is.

@paulweb515 the --author lets you filter by author, so each one of us would have to run the script for our own commits, or I could run them for each author. When I tested it earlier today it only touched the 5 commits I wrote, leaving everyone else's in tact. I figured this way it was more useful as a generic script in case you ever run into this problem with committers again.
