A very simple CLI script for code refactoring. Basically combines ack + gnu-sed

rename-inline.sh

#!/bin/bash

original="$1"
replacement="$2"

echo "Replacing $original with $replacement"
ack -l $original * | cut -d: -f1 | uniq | xargs gsed -i "s,$original,$replacement,g"

if [ -z $3 ]; then
original=`echo $original | tr '[:lower:]' '[:upper:]'`
replacement=`echo $replacement | tr '[:lower:]' '[:upper:]'`
echo "Replacing $original with $replacement"
ack -l $original * | cut -d: -f1 | uniq | xargs gsed -i "s,$original,$replacement,g"

original=`echo $original | tr '[:upper:]' '[:lower:]'`
replacement=`echo $replacement | tr '[:upper:]' '[:lower:]'`
echo "Replacing $original with $replacement"
ack -l $original * | cut -d: -f1 | uniq | xargs gsed -i "s,$original,$replacement,g"
fi;
