Hi,
Need some help here on a script I'm writing. I know that STDERR is normally done is this manner:

Hi there,
I was wondering if it was possible to pipe stderr to another process.
I need to eval commands given as arguments and I would like to redirect stderr to another process.
I can redirect stderr to a file like this...
toto:~$ command="one=1"
toto:~$ eval $command 2> error

Can somebody explain to me why the diff output is not going to stderr?
Yet when I issue a diff from the command line the return code is -ne 1.
I am guessing diff always writes to stdout???
Is there away I can force the difff to write to stderr USING THE CURRENT
template. If possible, I... (5 Replies)
Hello
I try to store stderr into a variable, then if this var is not empty i send an email and stop my script.

Hello,
Can you please if the bellow is the proper way of appending a variable to the stderr:
The easiest way to test this,I was able to imagine, was by touching 5 files and afterwards looping trough to the results:

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.
