Listing each branch and its last revision's date in git

I need to delete old and unmaintained branches from our remote repo. I'm trying to find a way with which to list the remote branches by their last modified date, and I can't.

Does someone know of an easy way to list remote branches this way?

Answer

commandlinefu has 2 interesting propositions:

for k in `git branch | perl -pe s/^..//`; do echo -e `git show --pretty=format:"%Cgreen%ci %Cblue%cr%Creset" $k -- | head -n 1`\\t$k; done | sort -r

or:

for k in `git branch | sed s/^..//`; do echo -e `git log -1 --pretty=format:"%Cgreen%ci %Cblue%cr%Creset" $k --`\\t"$k";done | sort

That is for local branches, in a Unix syntax. Using git branch -r, you can similarly show remote branches:

for k in `git branch -r | perl -pe 's/^..(.*?)( ->.*)?$/\1/'`; do echo -e `git show --pretty=format:"%Cgreen%ci %Cblue%cr%Creset" $k -- | head -n 1`\\t$k; done | sort -r

Michael Forrest mentions in the comments that zsh requires escapes for the sed expression:

for k in git branch | perl -pe s\/\^\.\.\/\/; do echo -e git show --pretty=format:"%Cgreen%ci %Cblue%cr%Creset" $k -- | head -n 1\\t$k; done | sort -r 

kontinuity adds in the comments:

If you want to add it your zshrc the following escape is needed.

alias gbage='for k in `git branch -r | perl -pe '\''s/^..(.*?)( ->.*)?$/\1/'\''`; do echo -e `git show --pretty=format:"%Cgreen%ci %Cblue%cr%Creset" $k -- | head -n 1`\\t$k; done | sort -r'

In multiple lines:

alias gbage='for k in `git branch -r | \
  perl -pe '\''s/^..(.*?)( ->.*)?$/\1/'\''`; \
  do echo -e `git show --pretty=format:"%Cgreen%ci %Cblue%cr%Creset" $k -- | \
     head -n 1`\\t$k; done | sort -r'
