I have lots of text files that have a different number of lines of text in them.
In Mac OS Finder, is there any way to search for files that are less than 21 lines? (i.e. each file has less than 21 line of text in them).
The Search for files gives lots of options, but I can't see one that is for line length.
From reading up on the subject, it seems using Grep in Terminal may be the best way, but I haven't found any sources that explain how to use Grep to search for line length on multiple files.
