Shell Programming and Scripting

Im tyring to create a script that will show me any lines in a file with todays date and yesterdays, the date format in the file is as follows



----- amqxfdcx.c : 728 --------------------------------------------------------
07/12/05 09:53:20
AMQ6109: An internal WebSphere MQ error has occurred.

EXPLANATION:
An error has been detected, and the WebSphere MQ error recording routine has bee
n
called.
ACTION:
Use the standard facilities supplied with your system to record the problem
identifier, and to save the generated output files. Contact your IBM support
center. Do not discard these files until the problem has been resolved.

It would be nice if I could capture the whole message, not sure if that is possible, but at least if the script could print out any times todays date and yesterdays is in written in the log

This Ruby program will do it:

Code:

today = Time.now.strftime('%m/%d/%y')
yesterday = (Time.now - 24*60*60).strftime('%m/%d/%y')

array=ARGF.read.split(%r!(^\d+/\d+/\d+)!)

(1..array.size).step(2){ |i|
  if (array[i] == today) or (array[i] == yesterday)
    print array[i] + array[i+1]
  end
}

what shell is this written in?

It's written in the Ruby programming language. Think of it as a much more powerful replacement for Awk. I'd recommend installing it if you don't already have it.
