Answer 1

With Bash

shopt -s extglob
ls !(*Thomas).txt

where the first line means "set extended globbing", see the manual for more information.

Some other ways could be:

find . -type f \( -iname "*.txt" -a -not -iname "*thomas*" \)

ls *txt |grep -vi "thomas"

Answer 2

You can use find to do this:

$ find . -name '*.txt' -a ! -name '*Thomas.txt'

Answer 3

If you are looping a wildcard, just skip the rest of the iteration if there is something you want to exclude.

for file in *.txt; do
    case $file in *Thomas*) continue;; esac
    : ... do stuff with "$file"
done
