OK, here's a patch to fstat(1) which adds an "-s" option to stat(2)
a list of files on the command line. It's against -STABLE but
should still apply to -CURRENT. Comments are appreciated.
The only other addition I would like to have is have "-n" option
display everything numericaly as it does now, whereas no "-n"
would display everything in human readable format (users, groups,
modes, dates, etc.)
If someone else would like to do that, please patch away! :-)
Otherwise, I'll see if I can't get around to it some other time.
-Paul.
