Hi, all

I'm writing some auto backup/refresh script, do you
know any command that returns only size or extenstion
or a file? (there will be only one file in the
directory)

I know awk can return only a part of the output, but
somehow I cann't combine awk and ls -l successfully. 
ls -s returns some size I don't want, I'd like to have
size as shown in ls -l.

For the refresh script, I like to check file
extension, so if it's in gz, I'll gunzip; if it's Z,
I'll uncompress.

Thanks!

Andrea
