Search and Replace Recursively using sed and grep
I have done this so many times, still I find a new problem doing recursive search and replace each time! Here's one small shell script that puts the issues I had on the Mac doing search and replace on a directory recursively.
Save the file as rpl.sh, chmod it 755, and execute it like:
CODE:
-
./rpl.sh folderContainingFiles/ oldText newText
Does the job for me! This could be done in a single line, I got some ideas of using xargs etc, but all that did not work on my Mac (at least). So resorting to this.
CODE:
-
#!/bin/sh
-
grep -rl $2 $1 |
-
while read filename
-
do
-
(
-
echo $filename
-
sed "s/$2/$3/g;" $filename> $filename.xx
-
mv $filename.xx $filename
-
)
-
done
And yes, if you are going to use this, take a little time and do some argument checking before passing them around! Unless you think only a God user like you is going to use it!

The exec part here: wouldn’t it fork a new process for every file? Is that a good practice? I thought otherwise!

BTW, Manish has a way to do this using Perl – http://mannu.livejournal.com/406783.html.

I haven’t ever seen a better file than this. It solved me days of work, you are gorgeous.
I NEVER write comments to posts because I don’t have time, but this time I have 4 working-days of free credit that you have just saved me with this file.
Thanks. ezequiel.

For whole words, update line 7:
sed “s/\b$2\b/$3/g;” $filename> $filename.xx

sed -i ’s/oldText/newText/g’ `grep -ril ‘oldText’ *` works fine for me

A small improvement:
Change
mv $filename.xx $filename
by
cp $filename.xx $filename
rm $filename.xx
and original file permissions will be preserved

You can avoid the creation of a temporary file using -i option for sed:
1 #!/bin/sh
2 grep -rl $2 $1 |
3 while read filename
4 do
5 (
6 echo $filename
7 sed -i “s/$2/$3/g;” $filename
8 )
9 done
