git list all authors last commit date in a project

I want to ask if there is a command in git that can list all authors names with the last date of their commit

(for example , author mike last commit was on feb, 2, 2017)

Im using git on mac iOS terminal and I'm a beginner in using git

thanks

git log --pretty=%an%x09%ad | awk -F$'\t' '!seen[$1]++'

%x09 is character code 9, i.e. '\t'. -F$'\t' sets that as awk's field separator, seen[$1]++ is zero only the first time.

%an prints the author's name, and %ad prints the date of authorship.

This should get you pretty close. Save it and make it executable (chmod +x filename). Then, of course, execute it in your git project directory (./filename).

#!/bin/bash
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
for a in `git log --pretty="%an" | sort | uniq`; do git log --author="$a" --pretty="Author: %an Last commit: %ai" | head -n1; done
IFS=$SAVEIFS

I guess I should explain the strategy a bit. Essentially, we query git for all authors, then sort that list and winnow it down to unique entries:

`git log --pretty="%an" | sort | uniq`

Then for each of those unique authors, we do a git log for just that author and take only the top result, formatting it to our liking with --pretty:

git log --author="$a" --pretty="Author: %an Last commit: %ai" | head -n1

The rest is just the looping mechanism (bash's for loop). It didn't exactly work flawlessly for me, but reasonably close. Should be a good place to start tailoring it to your specific needs--enjoy!

NOTE: Added a couple of lines to the script related to IFS/SAVEIFS. This will fix the for loop breaking on author names with spaces in them, which is quite usual. Sorry to have missed that detail earlier.

The easiest option is to use the pretty format options to git to achieve this kind of thing.

In this case, you probably want something like:

 git log --pretty="%aD %an %ae"

git log will output in reverse chronological order by default, so the first occurrence of a name is their last commit. So on *nix systems, something like the following will get the line you want:

git log --pretty="Author: %an last commit: %ai" |grep "mike" |head -n1

Look at man git-log and the PRETTY FORMAT section for all the % macro options.
