How to make git log output that just shows date and hash on one line?

Question

I need to get the Date and commit results of a set of github in this format:

Date Commit
19 Mar 2015 b6959eafe0df6031485509c539e22eaf2780919c
1 Apr 2015 9a         


        

Answer 1

How about:

git log | awk '/^commit / { commit = $2 }
               /^Date: /  { printf "%s %s %s %s\n", $4, $3, $6, commit }'

Capture the commit information in the variable commit. When a date comes along, print the date and commit information.

It is often a bad idea to pipe the output of grep to awk; awk is perfectly capable of doing the filtering that grep does.
