Nice one, I'll try to counter this garbage GPT3 answer:
- I don't think the regex engine in Perl is implemented in Perl. It's probably implemented in C/C++, like grep. libpcre is in C anyway.
- Even if grep is/were more efficient, You might have consumed more time and energy thinking, typing and running "grep --only-matching --perl-regexp 'prefix \K\d+(?= suffix)'" than the suggested perl solution
- I might have consumed even more energy typing this reply. My computer is there, waiting for me typing, doing not much.
- tryauuum 4y agoshorter version of the grep command is grep -oP 'prefix \K\d+(?= suffix)' but yeah, I know it's easier to me because I did read man page at some point (while carefully avoiding perl manuals) actually even that is not true, perldoc on regular expressions really helps even grep users
- jraph 4y agoIn all honesty, I'm more likely to remember this form than the Perl one, and once it's in the shell history, any will do anyway :-)
