The default names for fields in awk are:
$0 - whole line
$1 - field 1
$2 - field 2
.........
NF is the number of fields on the line.
You can substitute a variable like "i" for numbers of fields: "$i" is the field
that when i is evaluated, that field number is referenced.
Thanks for the reply Jim, I apologize in advance for my newbishness
I have a text file of lines like:
A=5|B=7|G=4|C=3|P=4|...
In other words, each line is a pipe-delimited set of pairs of strings of the form "X=Y".
What I want to do is find the token starting with "C", and print it and its value (so I'd want to print "C=3" in the example above).

SHUNIT2(1)SHUNIT2(1)NAME
shunit2 - A unit test framework for shell scripts
SYNOPSIS
shunit2 unitfile
DESCRIPTION
shUnit2 is a xUnit unit test framework for Bourne based shell scripts, and it is designed to work in a similar manner to JUnit, PyUnit,
etc.. If you have ever had the desire to write a unit test for a shell script, shUnit2 can do the job.
You can either run shunit2 directly from the commandline and specify the unit file or directly source the shunit2 executable.
If you directly execute shunit2 and don't specify a unitfile shunit2 assumes a empty testfile and will return without an error message.
EXAMPLE
Simple script to test if 1 equals 1
#! /bin/sh
testEquality()
{
assertEquals 1 1
}
# load shunit2
. shunit2
Execute shUnit2 unit tests directly from the commandline
shunit2 /path/to/unit/file
OPTIONS
shunit2 does not support any commandline options at all. You can either source shunit2 to execute your unit tests or directly run shunit2
as a commandline script.
SEE ALSO
For more information see http://code.google.com/p/shunit2/ or have a look at the installed documentation in /usr/share/doc/shunit2/
