I'd like to know if there is a catchall line for renaming the following patterns:
s01e03 -> 01x03
s4e9 -> 04x09
s10e08 ->10x08
and possibly even:
318 -> 03x18
1002 ->10x02
if its the first 3 or first digit number in the string.
thanks! (0 Replies)
Good Day,
Im new to scripting especially awk and sed. I just would like to ask help from you guys about a sed command that prints the line immediately after a regexp, but not the line containing the regexp.
sed -n '/regexp/{n;p;}' filename
What if my regexp is 3 word or a sentence. Im... (3 Replies)
Hi,
maybe it is stupid question, but is it possible to match expression like this ? :
... // ... ( there is "//" somewhere on the line and on the end of the line there ISN'T "*/" )
I've tried something like : (in SED)
sed 's/\/\/'
but I need "*/" not to be on the end of the line ...... (2 Replies)
I would like to extract "1333 Fairlane" given the below text.
The word "Building:" is always present. The wording between Building and the beginning of the address can be almost anything. It appears the the hyphen is there most of the time.
Campus: Fairlane Business Park
Building:... (9 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.
