Homework and Emergencies Homework & Coursework Questions How to use xargs to repeat as a loop to grab date string? Post 302926932 by scopiop on Friday 28th of November 2014 03:54:47 PM
Old 11-28-2014
I have tried the approach to grep the date of the last line and cut out the Date field and I have problem of getting rid of the square bracket.

Code:
$cat /etc/httpd/logs/access_log | cut -d' ' -f4 
> [25/Nov/2014:12:00:01

How do I remove the square bracket from most left? I have tried to use grep but
Unsuccessful to get rid of the bracket. After removed the bracket I think I can use
date "14 days ago" to set a stop point where I can count for all requests between those
date. I hope I got the right approach from here.

Thank you for your help,
Scopiop

__________________________________________________________________________________________________________________________________________________

NAME
textutil::repeat - Procedures to repeat strings. SYNOPSIS
package require Tcl 8.2 package require textutil::repeat ?0.7? ::textutil::repeat::strRepeat text num ::textutil::repeat::blank num _________________________________________________________________ DESCRIPTION
The package textutil::repeat provides commands to generate long strings by repeating a shorter string many times. The complete set of procedures is described below. ::textutil::repeat::strRepeat text num This command returns a string containing the text repeated num times. The repetitions are joined without characters between them. A value of num <= 0 causes the command to return an empty string. Note: If the Tcl core the package is loaded in provides the command string repeat then this command will be implemented in its terms, for maximum possible speed. Otherwise a fast implementation in Tcl will be used. ::textutil::repeat::blank num A convenience command. Returns a string of num spaces. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category textutil of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. SEE ALSO
