How can I get git log to print the full hash and short stats of each commit on one line?

Question

I would like to get this kind of output with git command line:

bcfd649de8850e3bfc9584eb12be8fe136ca6985 3 files changed, 8 insertions(+), 1 deletion(-)

I'm currently using git log --shortstat --reverse --pretty=oneline, but it's actually not a single line and the comment is useless to me:

bcfd649de8850e3bfc9584eb12be8fe136ca6985 Added ActionController#cookies[] as a reader for @cookies that'll return the value of the cookie instead of 
3 files changed, 8 insertions(+), 1 deletions(-)

Is there any way to do it?

Answer 1

You can define your own format consisting only of the full hash, and pipe the output of git log to awk (edit: or sed, as proposed by jthill in his comment) in order to replace newlines by spaces where needed (see this):

git log --pretty=tformat:"%H" --shortstat | awk 'ORS=NR%3?" ":"\n"'

or

git log --pretty=tformat:"%H" --shortstat | sed 'N;N;y/\n/ /'

Test

$ git log --pretty=tformat:"%H" --shortstat | awk 'ORS=NR%3?" ":"\n"'

Answer 2

For anyone landing here for an answer to "how to get git log one line full commit hash", as I did, there is a flag for the git log which prints the non-abbreviated commit hash.

It's called --no-abbrev-commit. Documentation reads as:

Show the full 40-byte hexadecimal commit object name. This negates --abbrev-commit, either explicit or implied by other options such as "--oneline". It also overrides the log.abbrevCommit variable.

TL;DR: Here is the command for the one-line output with the full commit hash:

git log --oneline --no-abbrev-commit
