you're counting Ns as legit fields while they should be skipped
there's no provision to print lines with more than 2 unique field values
'delete a' doesn't work on all awk-s. Most awk's don't allow deleting the whole array that way, but only individual array entries. Therefore, the trick is to use 'split' to null-out the array in one step.
To further my fledgling knowledge of C, I am re-writing some of the Unix command set. My current command is an ls-style command.
All works well, except for device files. How do I get the major/minor numbers for the dev files?

Hi
Can anyone tell me what is major number and minor number in the mknod command. Also what these numbers mean.
I have gone through the man pages but still I couldn't understand.

Good evening ...
does anyone of you know how to change major/minor numbers of disk devices ?
I had to migrate from raid1 to raid5 and this messed up my ASM cluster - I know which devices should have which IDs to match the content - but I have no idea how to change it.
Any help would be... (2 Replies)
Hi,
I have line like this :
proj_name/module/trunk/module_1_0
where the first "1" refers to major version and second "0" refers to minor version.
any AWK or command like that so that I can filter out the major and minor ?
like major= command | input line

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.
