We are told that Unix is very convenient to do various routing and boring jobs.
Multiple files search and replace in one of them.
However, it is not so intuitive for ordinary user to use.
Indeed, there are already plenty web pages show how to do it, but its not easy to remember the long command.
I’ve written a small sh script and found it useful (at least for me).
#!/bin/sh
if [ $# -gt 5 -o $# -lt 4 ]; then
echo "Usage searchReplace.sh <basePath> <filenamePattern> <searchPattern> <replaceStr> [separator]"
exit 1;
fi
SEPARATOR=/
if [ $# -eq 5 ]; then
SEPARATOR=$5
fi
for filename in `find "$1" -name "$2" -type f -print0 | xargs -0 grep -l "$3"`
do
echo "File $filename contains pattern, replacing."
cp $filename $filename.old
sed -e 's'"${SEPARATOR}$3${SEPARATOR}$4${SEPARATOR}"'g' $filename
done

Save it as searchReplace.sh and place it in the path you like.
Oh, don’t forget to chmod 755 it.
