The Sed FAQ

My favourite use case is when ssh complains about a host key being changed. I just substitute the offending line number into this: sed -i <line_no>d ~/.ssh/known_hosts and I'm done. Obviously I don't do that thoughtlessly otherwise I'd just disable ssh hosts checking altogether.

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!

Hello. It is always nice with more stuff on sed, Here is a nice link for those wanting to learn the basics: http://www.grymoire.com/Unix/Sed.html

My traditional reference for sed syntax (though hardly so well-explained, it can usually get the job done).
