Full Discussion: How to use xargs to repeat as a loop to grab date string?
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
