silver searcher ignore multiple directories

Question

using The silver searcher how can I ignore multiple directories?

I tried ag foo --ignore-dir dir1,dir2 but it doesn't work.

Answer 1

You an also do this (without needing to repeat the flag):

ag foo --ignore-dir={dir1,dir2}

You need to use this format with more than one directory. Otherwise, if it's with just one directory, you'd need to provide a comma, like: ag foo --ignore-dir={dir1,}.

Answer 2

you can specify the argument multiple times

ag foo --ignore-dir dir1 --ignore-dir dir2
