Sometimes you may find yourself needing to find and replace a word recursively inside a folder. This can be a big pain and while it usually is best to manually go through each yourself to be sure you are making the correct changes, in the right circumstances it can be pretty awesome to just do it automatically.
Heres a one liner to do just that. You may need to install xargs.
grep -rl 'string1' somedir/ | xargs sed -i 's/string1/string2/g' # an example, change hello to goodbye grep -rl 'hello' apps/my_app/ | xargs sed -i 's/hello/goodbye/g'
