My client git version is 1.7.0.4.
I want to automatically add a "Signed-off-by" line for the committer at the end of the commit log message when commit a message.
git config --global format.signoff true
, and run git commit -m "modify something"
, I see no "Signed-off-by" in git log
.git commit -m -s "modify something"
, then "Signed-off-by" does show in git log
.Can anyone help?
Update for Git 2.14.x/2.15: as I mentioned in "Git - Detect if commit is signed off programmatically", you will be able to parse a commit message trailer for Signed-off-By
line.
"
git interpret-trailers
" has been taught a "--parse
" and a few other options to make it easier for scripts to grab existing trailer lines from a commit log message.
See stefanct's answer for commit-msg
client-side hook which would use git interpret-trailers
.
Original answer (2013)
format.signoff
is about patch (as illustrated, for instance, in this patch):
format.signoff
A boolean value which lets you enable the -s/--signoff option of
format-patch
by default
It has no bearing on git commit -s
.
In other words, you don't have to signoff every commit, but when you are publishing them as patch for others to use (as in "git: submitting patches"), then you should sign them.
For the exact signification of Signed-of-by
, see "What is the Sign Off feature in Git for?".
