Hi all,
I hope my post is ok as I am not sure where to post it or what web-sites I
should be looking at.
I wanted to find out if there are jobs available in Australia for a junior
Linux systems admin more than likely in the Sydney area.

You want to count the total number of characters in a file, not including
newlines, that are on lines that don't start with a comma.

No sir! But shell usually wins.

Yes. That's much better. Slurping the input into memory doesn't
scale well.
And they said TIMTOWTDI applied only to perl.

Hi All,
In spite of being a staunch fan of configuring X with vi, i am looking
for a graphical configuration tool for Xorg. Especially one with good
multi-head support. So i am wondering if anyone has any thoughts.
Generally i am a debian man, but am willing to go with suse, fedora etc.

Timing test: say the above takes time 1.0
then the following takes time 0.46 ...
python -Sc import sys; print sys.stdin.read().count(',')
both are much much faster

I nominate the perl soln as the winner so far: runs like
a bat of out hell and is the most easy to understand.

I have to disagree. Whilst it may be fast, its not 100% correct.
Most of the time it would probably work, but if there are any blank lines,
it outputs the current count, and starts again.
Consider the following file contents:

I have a driver for the Lucent winmodem which is available as a deb for
i386, but I can't find one to run on 64bit debian. Is one available or
am I better off installing the 32bit Debian on my daughter's AMD X2
system and running the one I have?
I've personally never had a problem with SaX2 (X config tool in yast2)
and it's dual-head/Xinerama options, though it doesn't have a
web-based interface. I'd think success with multi-head on any distro
depends a lot on the graphics card (my geforce 6200 with proprietary

Would you be better of to scan ebay for an old EXTERNAL modem, plug that into
