Nice little bash script to show better information on a git commit

loggr

#!/bin/bash
#
# Call on .gitconfig with: "!bash -ec 'loggr $0 | less -r'"
# Params:
#  commit - pass in commit to display just that commit
#
if [[ $1 != 'bash' ]]; then
   if [[ $1 =~ [0-9a-f]{7} ]]; then
      rl=($1)
   else
      rl=$(git rev-list --no-merges HEAD -- $1 | grep -ve '\w{41}')
echo $c
   fi
else
   rl=$(git rev-list --no-merges HEAD | grep -ve '\w{41}')
fi
esc=$(printf '\033')
for r in $rl; do
   git log -1 --name-status --abbrev-commit --pretty=medium --color=always $r | sed -E "s/^(M)\s/$esc[0;34m\1$esc[0m\t/g; s/^(D)\s/$esc[0;31m\1$esc[0m\t/g; s/^(A)\s/$esc[0;32m\1$esc[0m\t/g"
   echo -e '\r'
   echo $(printf '#%.0s' {1..80})
   echo -e '\r'
done
