# You can add this alias:

git config alias.change-commits '!'"f() { VAR=\$1; OLD=\$2; NEW=\$3; shift 3; git filter-branch --env-filter \"if [[ \\\"\$\`echo \$VAR\`\\\" = '\$OLD' ]]; then export \$VAR='\$NEW'; fi\" \$@; }; f "
To change the author name:

# git change-commits GIT_AUTHOR_NAME "old name" "new name"

# git change-commits GIT_AUTHOR_EMAIL "old@email.com" "new@email.com" HEAD~10..HEAD
# Alias:
# change-commits = "!f() { VAR=$1; OLD=$2; NEW=$3; shift 3; git filter-branch --env-filter \"if [[ \\\"$`echo $VAR`\\\" = '$OLD' ]]; then export $VAR='$NEW'; fi\" \$@; }; f "
