I am really really new to Unix. I'm lost with so many books around for different shell. I'm thinking of taking a course on Operating Systems but it contains a lot of Unix programming I think. For example, someone was talking about a "which" command. But I wasn't able to figure out what it does...... (10 Replies)

Hello,
I want to compress any given file or directory. I used
1)gzip
2)zip
But when I do "ls -l". I found that the zipped file is in fact greater in size than the original file.
Can you please tell me the commands which will show me the difference in its size. (2 Replies)

How can I create another file with only a portion of them (like 300 within 400) and get rid of the rest?
Thanks (5 Replies)

I want to find which pattern or strings have occurred more than one time so that I can remove unnecessary redundancy.
For example:

While build i am using "-g" to have debug information in build.
there are many object files (>500) due to which resultant shared file (.so) will have huge size.
I can't reduce optimization level.
Is there any way or flag is present by using which i... (2 Replies)

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.
