how would you solve this problem?
I have a file process.txt
I wanted to just grab data in "process" column.
Name process process_id status
Adminserver adminserver 22669 Running
Browser Engine browserengine 22846 Running
Cache Manager cachemanager 22740 Running
CG Log Dispatcher cglogdispatcher 22905 Running
Clarity clarity_webcluster 22950 Running
Query Completion Server completionserver 22782 Running
So I did this, but the problem is that I have to keep on piping to perl to get rid of spaces as long as there are in "Name" column so that awk can know what is in $2.
$ cat stuff | perl -pe 's,\ ,,' | perl -pe 's,\ ,,' | awk '{print $2}'
adminserver
browserengine
cachemanager
cglogdispatcher
clarity_webcluster
completionserver

ppmquantall
ppmquantall(1) General Commands Manual ppmquantall(1) NAME
ppmquantall - run ppmquant on a bunch of files all at once, so they share a common colormap SYNOPSIS
ppmquantall [-ext extension] ncolors ppmfile ... DESCRIPTION
Takes a bunch of portable pixmap as input. Chooses ncolors colors to best represent all of the images, maps the existing colors to the new ones, and overwrites the input files with the new quantized versions. If you don't want to overwrite your input files, use the -ext option. The output files are then named the same as the input files, plus a period and the extension text you specify. Verbose explanation: Let's say you've got a dozen pixmaps that you want to display on the screen all at the same time. Your screen can only display 256 different colors, but the pixmaps have a total of a thousand or so different colors. For a single pixmap you solve this problem with ppmquant; this script solves it for multiple pixmaps. All it does is concatenate them together into one big pixmap, run ppmquant on that, and then split it up into little pixmaps again. (Note that another way to solve this problem is to pre-select a set of colors and then use ppmquant's -map option to separately quantize each pixmap to that set.) SEE ALSO
