Matching filename in ls (bash)

Question

I have the following files

tcpdump-12
tcpdump-12.delay
tcpdump-24
tcpdump-24.delay

Is there a way to ls only the files

tcpdump-12
tcpdump-24

I can do

ls tcpdump-[[:digit:]][[:digit:]]

but I am looking for something more generic that can take any number of digits, something like tcpdump-[0-9]+ if I was using vim or python regular expressions.

Answer 1

One needs to turn on extended glob functionality of bash to be able to use the advanced pattern matching.

$ ls
tcpdump-12  tcpdump-12.delay  tcpdump-24  tcpdump-24.delay
$ shopt -s extglob
$ ls tcpdump-+([[:digit:]])
tcpdump-12  tcpdump-24

Answer 2

If you're sure that all the unwanted files end with '.delay' you can do this:

ls --ignore '*.delay'
