Hi,
I have an unwanted string at random lines of my verilog (*.v) file.
(* abccddee *) input A;
(* xyz *) input B;
(* 1234 *) output C;
I want a clean file like this:
input A;
input B;
output C;
the unwanted string begins with "(*" and ends with "*)" at multiple lines.
Any help... (2 Replies)
I am running a grep query for searching a pattern, and the output is quite huge. I want only the last 200 lines to be displayed, and I am not sure if tail will do the trick (can tail read from std in/out instead of files?).
Please help me out. (1 Reply)
Hello all,
I need to print all the lines before a specific string and print a custom message 2 lines after that.
So far I have managed to print everything up the string, inclusively, but I can't figure out how to print the 2 lines after that and the custom message.
My code thus far is:... (4 Replies)
Thanks everyone. I got that problem solved.
I require one more help here. (Yes, UNIX definitely seems to be fun and useful, and I WILL eventually learn it for myself. But I am now on a different project and don't really have time to go through all the basics. So, I will really appreciate some... (6 Replies)
Hi.
I need to filter lines based upon matches in multiple tab-separated columns. For all matching occurrences in column 1, check the corresponding column 4. IF all column 4 entries are identical, discard all lines. If even one entry in column 4 is different, then keep all lines.
How can I... (5 Replies)
First, please excuse my apparent lack of attempt as this is NOT the case. I have attempted to research this for hours and realize I am way out of my league. I am not a programmer, especially in Unix.
I have an old Alpha Unix system with a program that prints to a network printer using the LPR... (4 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.
