Code:
#!/bin/bash

NOW=$(`date +%s`)
last=$(( $NOW - 30*60 )) # last 30 minute
while read mth dy hhmmss A9 ; do

curr-time=$(date --date "${mth} ${dy} ${hhmmss}" '+%s')
if [[ "$curr-time" -ge "$last" ]] ; then
echo "${mth} ${dy} ${hhmmss} ${A9}"
fi
done < log.out



tried to use epoch (%s) but not able to use the date format which i have it in log file and +%s as it was giving the invalid date error :


Code:
-bash: curr-time=: command not found
- locked <0x000000050ef88b10> (a java.lang.Object)

NAME
pcap_set_tstamp_type - set the time stamp type to be used by a capture device SYNOPSIS
#include <pcap/pcap.h> int pcap_set_tstamp_type(pcap_t *p, int tstamp_type); DESCRIPTION
pcap_set_tstamp_type() sets the the type of time stamp desired for packets captured on the pcap descriptor to the type specified by tstamp_type. It must be called on a pcap descriptor created by pcap_create() that has not yet been activated by pcap_activate(). pcap_list_tstamp_types() will give a list of the time stamp types supported by a given capture device. See pcap-tstamp(7) for a list of all the time stamp types. RETURN VALUE
pcap_set_tstamp_type() returns 0 on success if the specified time stamp type is expected to be supported by the capture device, PCAP_WARN- ING_TSTAMP_TYPE_NOTSUP if the specified time stamp type is not supported by the capture device, PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device doesn't support setting the time stamp type.
