Hi. I have a bunch of text files, and I want to remove all the lines
which do *not* begin with a certain pattern. I haven't found any
software capable of doing this.

I'll be very grateful if you can recommend anything suitable for me.

TIA

Why use a text editor? Personally, I'd just use grep...you can use
it to search for a regular expression, and then only output the
matching lines. You can also invert it so that you get the lines
that don't match, if you wish. If you're interested in that, you
can try

You might look into the standalone utility, Line Stripper. It can be run
GUI or CLI. In GUI mode, you would checkmark the applicable boxes:

String to Find: _________
[x] String at Start of Line
[x] Drop Line if Not Present
