Find and replace with sed in directory and sub dir

Question

I run this command to find and replace all occurrences of 'apple' with 'orange' in all files in root of my site:

find ./ -exec sed -i 's/apple/orange/g' {} \;

but it doesn't go through sub directories.

what is wrong with this command?

Edited: here is some lines of output of find ./ command:

./index.php
./header.php
./fpd
./fpd/font
./fpd/font/desktop.ini
./fpd/font/courier.php
./fpd/font/symbol.php

Answer 1

In linuxOS:

sed -i 's/textSerch/textReplace/g' namefile

if "sed" not work try :

perl -i -pe 's/textSerch/textReplace/g' namefile

Answer 2

For larger s&r tasks it's better and faster to use grep and xargs, so, for example;

grep -rl 'apples' /dir_to_search_under | xargs sed -i 's/apples/oranges/g'

Answer 3

This worked for me:

find ./ -type f -exec sed -i '' 's#NEEDLE#REPLACEMENT#' *.php {} \;

Answer 4

Your find should look like that to avoid sending directory names to sed:

find ./ -type f -exec sed -i -e 's/apple/orange/g' {} \;

Answer 5

grep -e apple your_site_root/**/*.* -s -l | xargs sed -i "" "s|apple|orage|"

Answer 6

I think we can do this with one line simple command

for i in `grep -rl eth0 . 2> /dev/null`; do sed -i ‘s/eth0/eth1/’ $i; done
