thanks a lot! It works when I drop off '-f'.

One more question: why does it work when I use '-f' in c shell?

This is not a problem in my case, since all files in my current directory do not have a name starting with ".".

See my script below(I did not quote it at all):



it gave the error message in my last post. But if replace 'ls ./*' with 'ls ./', it works. thanks a lot!

When I run the script, it gives the following message:
"ls: ./*: No such file or directory"

I can not understand why (I directly type "ls ./*" at command line, it works).

I tried to use the wildcard '*' in my bash script, but I can not get it work. Here is a simple example (list file names in current directory):
ls ./*
does not work in my bash script. But it works...

thanks a lot!

Say I have a number x=123, but I want to it be x=000123, because I need to use it in as a file name. thanks!
