List all the files in ending with several file extensions? If I want files ending with `.fas` I know I can do the following with `ls` command : ls -l /users/jenna/bio/*.fas and this lists out all the files ending with `.fas`. But how can I get files ending with either `.fas` or `.pep` ? `ls -l /users/jenna/bio/(*.fas | *.pep)` doesn't seem to work ? I know there might be other commands that can do this, but is there a way to make it work with `ls` ? Thanks for any help !

Use this: `ls -l /users/jenna/bio/*.{fas,pep}`

Or this: `find /users/jenna/bio -iname '*.pep' -or -iname '*.fas'`
