Hi!
I'm writing a program that test wich users are on
Code:
who | cut -d' ' -f1 > users
echo "The current users are: "
sort users
then enters a loop that will wait 5 seconds then test which users are on then compare it to who was on before. If no one has logged on or off it will echo "no one has logged on/off" but if somebody has it will echo their username and "has logged on" or their username "has logged off"
So far I have:
Code:
while true
do
sleep 5
who | cut -d' ' -f1 > 5secs
sort 5secs >/dev/null
#???cmp users 5secs
if [$? -eq 0]
then
echo "No users have logged in/off in the past 5seconds"
else
diff users 5secs#???5secs > usersdone
but I'm not sure if theat's how to correctly use the cmp method to test for differences. Also I have no idea how to use diff to compare the two correctly and return if users have been added or removed and what their names are.
Can anyone help me to figure out how diff can be used this way? Or is there another command to use?
any help with these would be appreciated

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
