Hi,

My company has a RH Linux AS server \( Linux 2.4.21-27.0.2.ELsmp \).

I'm  currently writing some shell scripts. I observed that if I vi a file with .fs extension. It prompts me the following error: 

"123.fs" 0L, 0C
W18: Invalid character in group name

If I vi a file with no .fs, it  is normal. But when I change its name with .fs extensive, the problem occurs.

I have tried other linux, but no problem.

What's happen? Did my linux vi corrupt? or it recognize special file extension?

Have a look at this URL

You will different file associations for .fs

The one, I think which matters is related to NetBSD. Just a guess only.
