Another handy script:

#!/bin/sh
# Rename a Zee command
old=$1
new=$2
find . -name "*~" -delete
rgrep -l $1 src | xargs rep "s/\"$1\"/\"$2\"/"
rgrep -l $1 tests | xargs rep "s/$1/$2/"
mmv "tests/$1.*" "tests/$2.#1"
mmv "tests/interactive/$1.*" "tests/interactive/$2.#1"
mmv "tests/regression/$1.*" "tests/regression/$2.#1"
mmv "tests/zile-only/$1.*" "tests/zile-only/$2.#1"
mmv "tests/zile-only/fixed-screen/$1.*" "tests/zile-only/fixed-screen/$2.#1"
mmv "tests/zile-only/interactive/$1.*" "tests/zile-only/interactive/$2.#1"
