UNIX for Dummies Questions & Answers

Well, I've searched the forum, but couldn't find an option, that would help me. I'm really a dummie in unix, so here it goes.

I've got like 50k files in a single catalogue. One of them contains a string:
Including the box/square brackets. I tried to find it manually, and use some search scripts, but they consider [] some sort of a special character. Tried to do \[text\] didn't work either.

Anyone knows, what to do?

If the issue has been already solved on this board previously, then I'm deeply sorry, but my dumb brain failed to find it. If so, please do not lock my topic without an explanation, and just point me towards to a solution, thanks.

Code:

find /path/to/50k/files -type f -exec grep -l -F '[some random expression]' {} \;

grep -F 'pattern' uses a string not a regular expression.

It works just fine. Thank you a lot. You, sir, are a genius! I salute you, Jim!
I consider the topic fulfilled.
