Hi,
I am using korn shell.
until ]
do
echo "\$# = " $#
echo "$1"
shift
done
To the above script, I passed 2 parameters and the program control doesn't enter inside "until" loop. If I change it to until ] then it does work.

Hi. I've been playing around a bit. This isn't for any practical purpose-- it's really just a theoretical exercise. I wrote this little thing:
foreach num ( 6 5 4 )
awk -v "number=$num" 'BEGIN{for(x=0;x<$number;x++) printf "-"; printf "\n"}'
end
I would expect the following output:

it seams that my ctrl+c and my ctrl+d don't work. if I type a bunch of jiberish on a line and ctrl+c I expect the command to be cancelled and to be given a fresh prompt, but instead it just putts ^C at the end of the line.
Also, ctrl+d should close the session, but instead mine just puts ^D at... (3 Replies)

cat .servers | while read LINE; do
ssh jason@$LINE $1
done
exit 1
./command.ksh "ls -l ~jason"
Why does this ONLY iterate on the first server in the list? It's not doing the command on all the servers in the list, what am I missing?
Thanks!

v4l-conf(1) General Commands Manual v4l-conf(1)
NAME
v4l-conf - configure a video4linux driver
SYNOPSIS
v4l-conf [ options ]
DESCRIPTION
v4l-conf is a small helper tool. It figures out the video mode and framebuffer base address of the graphics board and configures a
video4linux driver like bttv. This is needed for drivers which can DMA the video over PCI directly into the video memory.
Usually it is not required to use v4l-conf manually, xawtv(1) and fbtv(1) run it automatically at startup. It might be useful for trouble-
shooting. v4l-conf must be installed suid-root.
v4l-conf knows three ways to get the informations:
* Query the X-Server using the XF86 DGA extention. This is the default if the DISPLAY environment variable is set.
* Query the framebuffer driver. This is the default if DISPLAY is not set.
* Query the console driver. This is used on mklinux only.
OPTIONS
-h Print a short description of all command line options.
-q Be quiet.
-d dpy
Use the X11 display dpy to get the parameters.
-f Use the framebuffer driver to get the parameters.
-c device
Set the video4linux device.
-b n
enforce n bpp color depth. Works for switching between 15/16 and 24/32 bpp.
-s n
Shift the video display by n bytes.
-a adr
Set framebuffer address to adr. The value should be specified in hex. This option is allowed for root only. You can't overwrite the
autodetected value, this switch is only useful if autodetect doesn't work because the X-Server lacks DGA support. You can put this
into /etc/conf.modules, as "post-install bttv ..." for example.
BUGS
Hope I havn't any security flaws in there. If you find one, drop me a note. Mails with patches are preferred :-)
