What you are asking is to create a resultset that all files minus pattern1 minus pattern2
The only problem for this is that we will have to use grep -v. The file matching patterns become regular expressions
Code:
??????.xls
# becomes regex:
[0-9]{6}\.xls
This will happen for every file you want to exclude. Otherwise, you cannot just
for five different files because each instance of !(pattern2) will show other patterns like pattern2 pattern3... etc.
Code:
# generalized solution
ls directory | grep -v -e 'regex1' -e 'regex2' -e 'regex3'
Therefore you have to construct 50 different regexes (one for each file you have to specify) and apply some of them to the correct directory output from ls. I cannot do that for you.
