Default Negative Wildcard Matching

Hello,

In the shell, if you want to match a group of items based on a condition, you could use a wildcard. For example, if there was a bunch of .txt files in a directory, you could list only those items with % ls *.txt

Is there a way to match items based on the exclusion of a condition. Going with the .txt example, how would I select only those items in the directory that don't end in .txt?

I'd pipe it to grep:
% ls | grep -v '\.txt\>'

If you are looking for a shell-globbing-only answer, I'm not sure.

You may want to use '$' for end of line, otherwise if you have a somefile.txt.bak it will get excluded by grep. E.g.:
$ ls | grep -v '\.txt$'

Thanks for the replies.

I have discovered that the caret symbol - ^ - is a shell glob that negates the normal meaning (works with tcsh at least).
