About the shell problem.
Note the "%e" for the day of the week because syslogd date stamps don't have the leading zero on the day.
About the concept:
The output from "dmesg" is a limited buffer of messages sent to the system console. It is of little or no use for application monitoring.
In your example the syslog daemon has forwarded some messages to console. I would expect them to appear in one of the main system logs too but if they don't this is a syslog configuration problem.
You can get all sorts of messages from "dmesg" - try the command just after a reboot!

Hi,
I don't know hot to make this command work:
ls -laR | grep "^-" | awk '{print $9}'| grep "$.txt"
It should return the list of file .txt
It's important to search .txt at the end of the line, becouse some file name have "txt" in their name but have other extensions (13 Replies)

I am trying to do an rsh grep to search for date records inside server logs by doing this :
xx=`date +"%a %b %d"`
rsh xxx grep "^$XX" zzz
gives :
grep: 0652-033 Cannot open Jun.
grep: 0652-033 Cannot open 11.
But if I do :
xx=`date +"%a %b %d"`
grep "^$XX" zzz
it works... (2 Replies)

I want to list all files/lines which except those which contain the pattern ' /proc/' OR ' /sys/' (mind the leading blank).
In a first approach I coded:
find / -exec ls -ld {} | grep -v ' /proc/| /sys/' \; > /tmp/list.txt
But this doesn't work. I got an error (under Ubuntu):

Hello.
Following recommendations for one of my threads, this is working perfectly :

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.
