grep - search for an "option" - text itself is a valid command parameter [solved

[Sprintrdriver]

Hi folks. Have som beginner-issues using grep here.
I'm up to search for the term "--prune-empty-dirs" in the man page of rsync. So I tried to ran this command:

Code:

man rsync | grep '--prune' -A1 -B4'

Problem is I get error grep: unrecognized option '--prune'.[size=1em]How can I make grep to recognise the text pattern "--prune" as the pattern to search for?[/size][size=1em]I can remove the two dashes, but that is not what I want to do.[/size][size=1.45em][edit while write post][/size]Ok, I found the solution after I remembered to search the web for "grep escape character" (that is probably what I should had ask for) - so I got it to work with the same command, but backslashes in front of all dashes:

Code:

man rsync | grep '\-\-prune' -A1 -B4

Use double quotes: man rsync | grep "\-\-prune" -A1 -B4

Please set the topic as solved even if you found the solution yourself. It saves time from the rest of us.
Thanks!
