Top Forums Shell Programming and Scripting [Solved] I need help with a text file. Post 302566321 by johankor on Thursday 20th of October 2011 06:42:07 AM

Thank you for your reply, It is my first post in this forum so I made some mistakes writing the text file. The file is not a single continuous stream. It is broken by newlines, it has 3 columns; the first column is frequency, the second is the power and the third one is the Number of repeat value of that power in the second column. I would like to obtain for each frequency the maximum repeated power value. So in my file for 0.5000 frequency the maximum repeated power is -146 since it has repeated 122 times(3. column).

So my new file should look like this;

0.5000 -146 122
0.5452 -97 14
16.000 -164 151

I hope this explains better.

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/ AUTHOR
shunit2 was written by Kate Ward <kate.ward@forestent.com>. This manpage was written by Ulrich Dangel <mru@spamt.net>. 2.1.6 03/25/2012 SHUNIT2(1)
