remove files excluding those with specified extensions

FYI: I wasn't trying to start a flame war either. As pointed out in my prior post I haven't really bothered to learn bash because I'm comfortable with ksh and use it on my other *Nixes.

That said: I can't resisting pointing out that "/" is one keystroke whereas "ctrl-r" is two.

P.S. REAL hackers use buffer overflows and don't ever bother with shells.

Umm... I don't know why you can't get it to work. It works fine for me:

Code:

$ ls
framework_116.php  functions_116.php  get-pip.py       lqsed.txt    read_sed.sh
framework_117.php  functions_117.php  health_logs.txt  newfile.txt  regex.html

Code:

$ ls | grep -v 'txt\|sh\|php'
get-pip.py
regex.html

If you use it in a loop in a script, check if you have spaces in the file name. Common pitfall. Read more here:
