Regular expressions

[zz0rk]

Does the use of regular expressions require Go to be installed?

$ f2 -f ((.*?)) -r '-'
bash: syntax error near unexpected token `('

Thank you

No, you should enclose the find expression in quotes:

$ f2 -f '((.*?))' -r '-'

Thank you for your reply.

I am trying to match a pair of parenthesis and everything inside it, see

https://github.com/ayoisaiah/f2/wiki/Regular-expressions
((.*?)) Match a pair of parenthesis and everything inside

The above syntax will generate
bash: syntax error near unexpected token `('

Your suggestion in your reply from above will generate
f2 -f '((.*?))' -r '-'
INFO Failed to match any files

In this case
'Test (some text)' will remain unchanged when the expectation was for it to be changed to
'Test -'

Thank you

@zz0rk You need to escape the outer parentheses:

[zz0rk]

f2 -f '((.*?))' -r '-'
INFO Failed to match any files

I don't know what I am doing wrong here

[ayoisaiah]

You're not including the backslash:

$ f2 -f '\((.*?)\)' -r '-'

[zz0rk]

I've been copying and pasting the command directly from your comment into my terminal and also typed it manually. Same result.

I have noticed that when I preview this comment the backslash gets removed, so in fact the syntax I've been using was correct, but didn't pay attention that when the comment get's posted the backslash gets removed.

@zz0rk That's weird, I'm unable to reproduce. What version of f2 are you using?

[zz0rk]

I am running a current version of Debian 11. I've tested on a second box and I am getting the same results. I can upgrade to the latest version of F2 later today, but the version I am running right now doesn't work.

[zz0rk]

Curiosity got the better of me... still no dice

[ayoisaiah]

I just tested on Debian 11, same result for me. Are you using bash or some other shell?

[zz0rk]

Man, this is weird. I don't have anything fancy.

[ayoisaiah]

I'm going to close this issue, because I couldn't reproduce it on of my setups.
