Full Discussion: Saving output from awk into a perl variable
Top Forums Shell Programming and Scripting Saving output from awk into a perl variable Post 302244922 by userix on Thursday 9th of October 2008 03:21:59 AM
Old 10-09-2008
I want to search for a number found in the 4th column on a specific line in a file and store that value into a variable. This file contains over 7000 lines of data. The specific line I am looking for contains the letters 'OXT' This is why I was thinking of using awk to find the line that contains 'OXT' and then grab the number from the 4th column of that line only. Would that work with split?

version.4th

VERSION.4TH(8)						    BSD System Manager's Manual 					    VERSION.4TH(8)

NAME

     version.4th -- FreeBSD version string boot module

DESCRIPTION

     The file that goes by the name of version.4th is a set of commands designed to draw the boot loader version at the bottom-right of the
     screen.  The commands of version.4th by themselves are not enough for most uses.  Please refer to the examples below for the most common sit-
     uations, and to loader(8) for additional commands.

     Before using any of the commands provided in version.4th, it must be included through the command:

	   include version.4th

     This line is present in the default /boot/menu.rc file, so it is not needed (and should not be re-issued) in a normal setup.

     The commands provided by it are:

	   print_version	  Prints the contents of the loader_version environment variable right-justified at the column loader_version_x
				  and row loader_version_y.

     The environment variables that effect its behavior are:

	   loader_version
		     Set automatically by loader(8), but you can override it by setting in loader.conf(5).  This should be the version of boot
		     loader used.

	   loader_version_x
		     Sets the desired ending column position of loader_version.  Default is 80.

	   loader_version_y
		     Sets the desired ending row position of loader_version.  Default is 24.

	   loader_color
		     If set to ``NO'' (case-insensitive) or ``0'', causes the version to be printed without color (default is ANSI Cyan).

FILES

     /boot/loader	The loader(8).
     /boot/version.4th	version.4th itself.
     /boot/loader.rc	loader(8) bootstrapping script.

EXAMPLES

     Override loader(8) version in loader.conf(5):

	   loader_version="loader 1.1"

SEE ALSO

     loader.conf(5), color.4th(8), loader(8)

HISTORY

     The version.4th set of commands first appeared in FreeBSD 9.0.

AUTHORS

     The version.4th set of commands was written by Devin Teske <dteske@FreeBSD.org>.
