I need to find in the /usr/bin all the files that has any charater as its fourth carater except a lowercase x or -. How do you write a shell script using the KornShell to do that using grep. example -r-xr-xr-x or drwxr-xr-x. I have tried this but it does not work.

ls -l /usr/bin|grep '^...[^x-]......$'|sort -r|uniq|wc -l

what am I doing wrong?

I beleive that I have a solution to the problem.

#!/bin/ksh
#Output all the files using ls -l /usr/bin and grep that has any #fourth charater except a lowercase x or -. Example -r-xr-xr-x #or drwxr-xr-x.
#sample use: nodashx

ls -l /usr/bin|tail +2|grep '^...[^x-]......'|sort -r|wc -l

exit

#I have tested this solution and it worked.
