Top Forums Shell Programming and Scripting To print lines between 2 timestamps using awk|sed and regex Post 302791063 by sarah-alikhan31 on Sunday 7th of April 2013 08:33:59 PM

I think the problem lies with the calculation of $dt_1 and $dt_3
Code:
dt_1=`date +%h" "%d", "%Y\ %l -d  "1 hour ago"`
 
dt_3=`date +%h" "%d", "%Y\ %l`

The space between Y and l, is the culprit Smilie
I had given this space to accomodate 2 digit hour. For 1 digit hr, if there is no space between Y and l, the script works fine.
Otherwise, it does nothing..(as happening with me till now)

Your script worked because there are 2 spaces between the year and the hr in the log file that you have shown:
2013 5
and so it could match exactly.
Smilie
If you could suggest something here....that would be much appreciated.
How should I modify my date format calculation to match in exact date in log file - bearing in mind 1 digit and 2 digit hr

NAME
stMktime, stWriteTime - date and time handling SYNOPSIS
#include <config.h> #include <sttk.h.h> time_tstMktime (char *string); char*stWriteTime (time_t date); DESCRIPTION
stMktime scans the given string and tries to read a date and time from it. It understands various formats of date strings. The following is a list of all valid formats, optional parts in brackets. [Tue] Jan 5[,] [19]93 This includes the standard asctime(3) format. Jan 5 With no year given, the year defaults to the current year. [19]93/01/05 This notation requires month and day represented by exactly two digits. 5.1.[19]93 This is the usual German notation. 5.1. German notation referencing the current year. A certain time, given together with the date must always have the following form. hours:minutes[:seconds] Each of the fields must be an integer value within the proper range (hours: 0-23, minutes and seconds: 0-59). Values below 10 may be written as one digit numbers. The time value may be placed anywhere in the date string: at the beginning, at the end, or somewhere in the middle. Any amount of white- space may be given between a field of the time value and the separating colon. The time is always considered to be local time. stWriteTime generates a time string similar to asctime(3) from its date argument. SEE ALSO
asctime(3) BUGS
Time Zone Names within the time string (like `MET') are not handled properly. In most cases they will cause a failure. sttk-1.7 Thu Jun 24 17:43:35 1993 sttime(3)
