[Bash] Recursively replace a string in multiple files in multiple directories!

[Marook]

If you need to replace a special string in multiple files in multiple directories, you won't find a recursive option in sed. So must combine grep in combination with xargs and finally sed for the replacement. The following one-liner should do the trick :

Code: [Select]

grep -ilr ‘old-string’ * | xargs -i@ sed -i ‘s/old-string/new-string/g’ @

where old-string = string which needs to be replaced
an new-string = new string which replace old-string
