Extract substring using regexp in plain bash

Question

I\'m trying to extract the time from a string using bash, and I\'m having a hard time figuring it out.

My string is like this:

US/Central - 10:26 PM          


        

Answer 1

Quick 'n dirty, regex-free, low-robustness chop-chop technique

string="US/Central - 10:26 PM (CST)"
etime="${string% [AP]M*}"
etime="${etime#* - }"
