This should be easy, but cannot quite do it.

here is the file:

9077/00:00///:8087
9079/00:00/////386/_

here is what I want

9077
9079

herre is my logic:
- remove from first / to end of line
- remove / charcter.

I am using system command. I am not sure how to tell to remove from the first character to end of line.

sed 's/\/*//g' pslog3


I've done it before, but I do not have my perl reference book here!!

please help
