Hi,
I want to just expand the macros in a set of c files from a filelist which are in different directories. I don't want the header files included in the c file to be expanded. I have a perl script which does
gcc -E <infile> -I <path to search for header files> -imacros <infile>
But in... (1 Reply)
Hi all,
I have a selection of files that contain several commands that write to a file and are started as background processes similar to below.

Hello,
I have this problem.
I have script file, e.g.
#!/usr/bin/ksh
echo $MY_DIR
ls -lt $MY_DIR
I want to list the script but with MY_DIR variable expanded. E.g.
MY_DIR=/abc/xyz (in shell MY_DIR is set)
So I want to list the script and see:
#!/usr/bin/ksh
echo /abc/xyz

and then subsequently wants to create an alias file from each pathname the find command retrieved and the > placed within 'newfile', how would one do this? Ideally, the newly created alias files would all be in one directory.

Hi Guys,
I have a raidz zpool that consists of four disks. 2x2TB, 1x1TB and 1x0.75TB.
Originally it was only 1x1TB, 3x0.75TB, and I had around 1.7TB of storage capacity. I've just switched out two of the 0.75TB disks for the 2x2TB ones. I did this one at a time and now the resilvering is... (2 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.
