Top Forums UNIX for Dummies Questions & Answers Subtract two dates in different lines Post 77551 by vino on Monday 11th of July 2005 01:40:37 AM

Here is a starting point for you.

Have converted your line (123123 05/11/30 12:12:56 145) into time since epoch.

Code:
#! /bin/sh

while read line
do
DATE=$(echo $line | awk '{ print $2 }')
TIME=$(echo $line | awk '{ print $3 }')
echo $(date -d "$DATE $TIME" +%s)

done < vanand.txt

vanand.txt contains

123123 05/11/30 12:12:56 145
145235 05/11/30 12:15:15 30
145264 05/11/30 13:14:56 178
.
.

After this, I think you need to store the values in an array and then do the comparison.

Cheers,
vino

RADEAPCLIENT(1) 						 FreeRADIUS Daemon						   RADEAPCLIENT(1)

NAME
radeapclient - send EAP packets to a RADIUS server, calculate responses SYNOPSIS
radeapclient [-c count] [-d raddb_directory] [-f file] [-h] [-i source_ip] [-q] [-s] [-r retries] [-S file] [-t timeout] [-v] [-x] server {acct|auth} secret DESCRIPTION
radeapclient is a radius client program. It can send arbitrary radius packets to a radius server, then shows the reply. Radeapclient dif- fers from radclient in that if there is an EAP-MD5 challenge, then it will be responded to. radeapclient is otherwise identical to radclient. The EAP-Identity attribute, if present is used to construct an EAP Identity message. The EAP-MD5-Password attribute, if present is used to respond to an MD5 challenge. No other EAP types are currently supported. OPTIONS
-c count Send each packet count times. -d raddb Set dictionary directory. -f file Read packets from file, not stdin. -r retries If timeout, retry sending the packet retries times. -t timeout Wait timeout seconds before retrying (may be a floating point number). -h Print usage help information. -i id Set request id to 'id'. Values may be 0..255 -S file Read secret from file, not command line. -q Quiet, do not print anything out. -s Print out summary information of auth results. -v Show program version information. -x Enable debugging mode. EXAMPLE
A sample session that queries the remote server with an EAP-MD5 challenge. ( echo 'User-Name = "bob"'; echo 'EAP-MD5-Password = "hello"'; echo 'NAS-IP-Address = marajade.sandelman.ottawa.on.c'; echo 'EAP-Code = Response'; echo 'EAP-Id = 210'; echo 'EAP-Type-Identity = "bob"; echo 'Message-Authenticator = 0x00'; echo 'NAS-Port = 0' ) >req.txt radeapclient -x localhost auth testing123 <req.txt SEE ALSO
