Clearing ocntents of file but retain permissions

Is there a way to clear the contents of a file without removing any of the permissions?

Currently I use the rm filename to removed the entire file but then I always have to go back in and rest the permissions.

Can anyone help me with a script that will clear the contents but leave the permissions intact?

Any help is greatly appreciated.

Thanks in advance..
Armando

Thumbs down

Ooops, yes, it should be cat instead of echo!

Code:

 cat /dev/null>/path2file

I tried this and it still took the permissions from the file. Any other ideas?

Which operating system?
I tested on Solaris and the permissions were not changed!
