i have a CIDR range in this regex

^5\.188\.62\.([1-9]?\d|[12]\d\d)$

I am able to confirm matching values using https://regexr.com

Now i am testing some code and i am using the following as a sample to test matches

 var='^5\.188\.62\.111';[[ $var =~ '^5\.188\.62\.([1-9]?\d|[12]\d\d)$' ]] && echo yes || echo no

In final, i am not able to get it working.

Any tip to solve?

Thanks

Shouldn't it be something like var=5.188.62.212? – Eduardo Trápani Jun 26 '20 at 15:07
When using =~, don't quote the thing on the right – Andy Dalton Jun 26 '20 at 15:08

FWIW [[ $var =~ '^5\.188\.62\.([1-9]?\d|[12]\d\d)$' ]] would be OK (and would match on var=5.188.62.111) in zsh instead of bash after set -o rematchpcre. – Stéphane Chazelas Jun 26 '20 at 15:25
