Replace string in all files using sed in linux

Posted on Feb 10, 2012

Replaces all ‘OLDSTRING’ to ‘NEWSTRING’ in all files

1

$ grep -rl OLDSTRING * | sort | uniq | xargs sed -i -e ‘s/OLDSTRING/NEWSTRING/’

or using find:

1

find */public_html/ -iname '*.php' -exec sed -i -e 's/OLDSTRING/NEWSTRING/' {} \;
