How can I use wildcard with exception in bash? [duplicate]

Question

I want to grep multiple files in a folder. I want to grep everyone of them except big files like pcap file and gziped files. So I am trying :

$ grep foo !({*pcap*,*gz*})

But that does not work. Because while it avoid gziped files, the shell expansion of !({*pcap*,*gz*}) returns pcap files actually. Any idea how to include every files except pcap and gziped files please?

Answer 1

The GLOBIGNORE parameter lists files to exclude from the results of a glob expansion:

Assuming the current directory is empty:

$ touch foo1 foo2 foo3 foo10 foo11 foo12
$ GLOBIGNORE="foo1*:foo3"
$ ls *
foo2

Answer 2

you need to change that to

grep foo  !(*pcap*|*gz*)

to exclude pcap and gz files
