Re: [PLUG] CLI for "find" text string in an unknown file

As a side note, if you end up with a directory with too many files in it for “ls” or “rm” to handle, this is a handy syntax to remember. This has happened to me a few times in the past with uploadable image directories that have gotten bigger than I ever expected.

Example, to delete a bunch of files from such a directory (don’t try this at home if you’re not sure of what you’re doing!):

find ./* | xargs rm

Another trick I use to automatically compress uploaded images (requires ImageMagick) that our field technicians failed to use an automated program to resize / compress:

find ./ -size "+200k" | xargs mogrify -quality 60 -geometry 600x10000

It is a very handy syntax to know and understand.

Or with only one tool, grep -rl <string> /path/to/top/directory

Or.. using xargs to avoid the crazy syntax of using -exec

find <directory> | xargs grep <string>
