I always have problems when running sed, especially with capture groups. I can never get the syntax right for non-trivial stuff.
I wish there was a sed-like tool that used python or javascript regex syntax!

perl -pe is my usual replacement for stuff where I want a sed-like filter but PCRE syntax.

Yep, as soon as my sed gets even slightly complicated I reach for s2p (sed to perl translator).
Also see a2p (awk to perl) and find2perl.

Perl regexes are PCRE-like,
PCRE regexes are Perl-like,
they are not the same.

#15My favourite use case is when ssh complains about a host key being changed. I just substitute the offending line number into this: sed -i d ~/.ssh/known_hosts and I'm done. Obviously I don't do that thoughtlessly otherwise I'd just disable ssh hosts checking altogether.
Isn't that what "ssh-keygen -R" command is for? Though I agree that your solution is more generic.
