Hi folks,
I'm trying to define the following command as alias in .cshrc file:
ls -ltr | grep ^d | awk '{print $9}' | xargs du -hs
I defined it as the following:
alias nirdirs '`ls -ltr | grep "^d" | awk "{print \\$9}" | xargs du -hs`'
I've got the following error when I've run the alias:... (7 Replies)
Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)
Hi,
I found on linuxgazette.net/93/bhaskaran.html page very useful sample of virtual driver (not connected to real hardware).
I try to compile it with no effect.

My source is saved in networkAdapter.c file in /usr/src/myModules directory.

Hi,
I have received an application that stores some properties in a file. The existing struct looks like this:

UINT uSizeIncludingStrings;
// copy of Telnet data struct

UINT iPortNr;

Hi
I'd say I'm having this weird problem where my script isn't taking the value off a variable or printing it. My code is like this:
set count_C= `grep -c C mols`
set count_H= `grep -c H mols`
set count_O= `grep -c O mols`
sed -i '7,7 s/$/ $count_C $count_O $count_H/g' input It... (8 Replies)

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.
