Replace git author using shell script

#github #shellscript

This is an old trick that saved me several times. Sometimes people forget to setup their name and email information. The following script is useful to fix mistakes:

#!/bin/sh

git filter-branch -f --env-filter '

an="$GIT_AUTHOR_NAME"
am="$GIT_AUTHOR_EMAIL"
cn="$GIT_COMMITTER_NAME"
cm="$GIT_COMMITTER_EMAIL"

if ["$GIT_COMMITTER_EMAIL" = "old@email.com"]
then
  cn="New author name"
  cm="new@email.com"
fi

export GIT_AUTHOR_NAME="$an"
export GIT_AUTHOR_EMAIL="$am"
export GIT_COMMITTER_NAME="$cn"
export GIT_COMMITTER_EMAIL="$cm"
'

echo "Run after"
echo "git push origin +master:master"
