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
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
