Look at this simple example.
echo " 2 4 6" | awk '{$2+=3;$3-=1}1'
2 7 5
Is there a simple way to update a field and at the same time keep the formatting?
I would like to get it like this
2 7 5
I have tested both sub and gsub, it reformat too. (2 Replies)
In the tab-delimeted input file below I am trying to use awk to update the value in $2 if TYPE=ins in bold, by adding the value of
HRUN= in italics. In the below since in line 1 TYPE=ins the 117282541 value in $2 has 6 added because that is the value of HRUN=.
Hopefully the awk is a start but I... (2 Replies)
Trying to use awk to:
update $2 in file2 with the $2 value in file1, if $1 in file1 matches $13 in file2, which is tab-delimeted. The $2values may already be the same so in that case nothing happens and the next line is processed.
There are exactly 4,605 unique $13 values. Thank you :).

In the out.txt below I am trying to use awk to update the contents of $9.. If $9 contains a + or - then $8 of out.txt is used as a key to lookup in $2 of file. When a match ( there will always be one) is found the $3 value of that file is used to update $9 of out.txt separated by a :. So the... (6 Replies)
In the awk below I am trying to set/update the value of $14 in file2 in

The lengths of $9 and $12 can be variable but what is consistent is the start pattern
will always be NM_ and the end pattern is always ;... (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.
