After the last two days, let’s see a less brain melting, but related topic, how to remove lines with given pattern from a file.
It’s not something I use daily, but with rust code, I use it a lot. Around
tests, sometimes there are
#[ignore lines to tell the system to ignore this
test function. When I’m done I want to remove all of those from the test file,
and the easiest way to use vim.
:global command executed an Ex (
: commands) command on the lines within
the provided range that matches a pattern. In this case we want to run
all lines that matches
^#\[ignore, so the command will be
