Using sed and filter-branch to prepend and append to Git commit messages without newlines
Raw
filter-branch-prepend-and-append
# Prepending text to the five most recent commit messages:
git filter-branch --msg-filter 'sed "s/\(.*\)/[prepended text] \1/g"' HEAD~5..HEAD
# Appending text to the five most recent commit messages:
git filter-branch --msg-filter 'sed "s/\(.*\)/\1 [appended text]/g"' HEAD~5..HEAD

Note that this prepends line by line. I.e. if you have multiline commit messages each line gets prepended the string.

# Prepending on the first line only:
git filter-branch -f --msg-filter 'sed "1 s/^/[prepended text]/g"' HEAD~5..HEAD
