Hello,

Thanks to everyone for their efforts. Sorry, was away for few days and didn't get the time to look at the solutions provided.

I tried all scripts from this forum but none of the script worked. All the scripts fetching the lines for entire day instead of last 30 min. My requirement is to pull the lines for last 30 min only.

Script used (for e.g.) :


Code:
awk -F "<|>| |, |," -v d="$(LANG=C date -d -30minutes -u +"%Y%m%d%T")" '
BEGIN   { split("Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec", m2b)
        for(i = 1; i <= 12; i++)
        b2m[m2b[i]] = sprintf("%02d", i)
}
/^</    { line=$0
        if ( length($3) < 2 ) $3 = "0" $3
        split($5, a, ":" s)
        if ($5 == 24) $5 = "00"
        if ($7 == "PM") $5 = (a[1]+=12) ":" a[2] ":" a[3]
        $0 = $4 b2m[$2] $3 $5
        if ( d < $0 ) print line
}
' file_1.out

Code:
$ date   ############ current Date/time on Linux when I ran the script

Sat Mar  9 18:53:47 UTC 2019



Output from the above script:

Code:
<Mar 9, 2019, 1:02:39,176 AM UTC> <Error> <Coherence> <BEA-000000>

<Mar 9, 2019, 1:13:22,583 AM UTC> <Error> <Coherence> <BEA-000000>
<Mar 9, 2019, 1:47:08,198 AM UTC> <Error> <Coherence> <BEA-000000>
<Mar 9, 2019, 5:16:42,24 AM UTC> <Error> <Coherence> 

<Mar 9, 2019, 6:50:41,556 PM UTC> <Error> <Coherence> <BEA-000000>
<Mar 9, 2019, 6:56:45,132 PM UTC> <Error> <Coherence> <BEA-000000>


Please suggest as I need to pull last 30 min lines only whenever i execute this script not for the entire day.
