Question

I want to remove blank and commented lined at one time. I already found the similar question regarding removing blank lines, so for blank lines I use:

:g/^$/d

and for commented lines:

:g/^#/d

I’m curious is there any way to merge these regex in one? Something like

:g/^[$#]/d

but obviously it doesn’t work in vim.

Answer 1

You can try this command:

:g/^\(#\|$\)/d

Or

:g/\v^(#|$)/d

• $ matches literal ‘$’ inside […] (type :help /$ for help)
• \| is for alternation
• \v is very magic (minimal backslash escape)
