sd fails to match when using ^ to delimit the beginning of the line

[Porkepix]

When trying some search & replace where I wanted to match something only if the line was starting with it, I wanted to use the usual ^ to flag the beginning of the line. The result was a fail of the match wail getting rid of it resulted in fine matching.
I tried to escaping it, guessing that as $ is used for variables, it probably needs some escaping to flag the end of a line the same way, but this didn't work as well.

I guess that ^and $ should somehow be usable to flag beginning and end of the line.

Yep. My sed regex to match HTML Tags <[^>]*> doesn't work.

I ran into the same issue.
Also I noticed that it works as expected on the first line,
so I enabled the multiline flag and it worked as expected afterwards.
E.g. shell history without line numbers:

history | sd -f m '^\s*[0-9]+\s+' '' | less

Thanks for reporting this @Porkepix. I also believe the multi-line flag makes more sense to have as a default, similar to sed.
