My script was going to be something along the lines of awk/if-then-else-fi/echo. :-) Can this be tweaked for directories also? You lost me after tr. -- Gary

Some shell hackery: set -- $(ls -l foo) OCTMODE=$(echo "ibase=2;obase=8;$(echo $1 | tr -- '-drlwcxb' '0 1 1 1 ')" | bc) Season to taste. Tweak for hex to octal conversion. ccb -- Charles C.

Check out the 'stat' command and 'stat -t'.

Permissions on a file

by Gary J. Hanley

Hello all, Does anyone know how I would go about listing the permissions of a file in octal format instead of symbolic? I need to pass that value to a script somehow, and although I could write a script to do that I didn't want to waste my time if there was already a command to do that. Thanks! -- Gary

REMINDER: Meeting Wednesday, July 18th, 7 PM

by Andy Stewart

HI everybody, This is a reminder of the upcoming WLUG meeting to be held this Wednesday, July 18th, at 7:00 PM in Kinnicutt Hall at WPI in Worcester, MA. The topic for this meeting will be "Using Digital Cameras with Linux". Marc Hughes will do a presentation / demo with his digital camera. I will then do a quick demo of gimp-print to print the images which Marc takes with his camera. I'll be bringing my Epson Stylus Color Photo 870 printer to the meeting with some 4x6 photo paper. After the meeting, a bunch of us will probably go to the Boynton Restaurant for pizza and beer. See ya there!

Re: [Wlug] USB hangs system - requires reboot

I'd suggest you enable that (and make sure SUSE doesn't disable it like redhat does) and when the system locks, you can try and get a traceback to see what's up.

That shouldn't matter, esp if you don't have your printer hooked up to both interfaces at the same time. As for your fsck woes, I'd get the latest version of ext3 instead, since you can enable/disable it without having to do a dump/restore conversion like you would for reiserfs. It's not in 2.4.6 by default, but it's easy to patch your kernel with it. Here's the URL: http://www.uow.edu.au/~andrewm/linux/ext3/ I'm running 2.4.6 with ext3 on SMP and it seems to work pretty well so far. No real stress testing yet tough. John

Hi Andy - The SystemV shared memory subsystem is now available as a filesystem under Linux.

Re: [Wlug] What is shmfs?

Well, here's what I know about it... shmfs = "Shared Memory File System" - contents sit in RAM and swap partitions - used to implement POSIX.4 shared memory support.
