Hi,
Thanks for your reply. I tried your syntax but it failed to do what I wanted. Actually what I passed on my previous post for browser1, browser2, browser3 were all different names: Safari, Opera, Firefox - so the regex in this case should be

Code:

(Safari|Opera|Firefox)

(is it correct, btw?) and since these are just parts then the question how do I define that arranging my regexes. I'd like it to be directories to be skipped (in which case I composed the regex as

Code:

'.*/(Safari|[Oo]pera|Firefox|[Mm]ozilla)/.*'

, though I feel uncertain of its correctness; I used this notation too with no or converse output than desired) or all types of files containing one of those names (

Code:

'.*(Safari|Opera|Firefox).*'

?). I'm not sure how to handle that.

In my case I tried

Code:

'.*(Safari|Opera|Firefox).*'

and in this scenario I appended find with -E option and prepended

Code:

'.*(Safari|Opera|Firefox).*'

with -regex so the most common variant to which other my combinations used could be reduced is

Code:

echo MYPASSWORD | sudo -S find -E / -regex '.*(Safari|[Oo]pera|Firefox|[Mm]ozilla).*' -prune -o -name '.*(keyword|KEYWORD).*'

I've tried so many variants I can barely remember what an option output what. I tried appending -exec (

Code:

echo MYPASSWORD | sudo -S find -E / -regex '.*(Safari|[Oo]pera|Firefox|[Mm]ozilla).*' -prune -o -exec grep '.*(keyword|KEYWORD).*' {} ';'

- it printed many lines of the kind "grep: .*(Safari|[Oo]pera|Firefox|[Mm]ozilla).*: no such file or directory") , I tried piping to grep the latter used as an argument to xargs (

Code:

echo MYPASSWORD | sudo -S find -E / -regex '.*(keyword|KEYWORD).*' | xargs -I {} grep -RLE {} '.*(Safari|[Oo]pera|Firefox|[Mm]ozilla).*'

and got the message "no termination character" or smth like that).
Right now it hanged with no output or error message at all executing

Code:

echo MYPASSWORD | sudo -S find -E / -name  '.*(Safari|[Oo]pera|Firefox|[Mm]ozilla).*' -prune -o -type f -exec grep -il *keyword*  {} ';'

. I tried using {} + at the end of this line instead of {} ';', I added and omitted -type option - no difference either. Interesting that when I used operators -and -not -path (or -name in place of -path) '.*(Safari|[Oo]pera|Firefox|[Mm]ozilla).*' it would return results containing one of those names/paths. That's just weird.
