Remove Duplicate lines from File

I have a log file "logreport" that contains several lines as seen below:

04:20:00 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping
06:38:08 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping
07:11:05 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping


I would like to edit the report to remove entries that report duplicate events. I am trying to produce an output close to what is seen below:

04:20:00 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping
This Error was reproduced 2 times

you can use uniq.

can be like this:
for i in `more logreport | sort |uniq `; do echo "no.of time &i:`grep -c $i logreport`"; done

Code:
awk '{x[substr($0,9)]++;y[substr($0,9)]=$1}END{
	for(i in x)
printf "%s\nThis Error was reproduced %d times\n",y[i]i,x[i]
}' logfile

As always, use nawk or /usr/xpg4/bin/awk on Solaris.

What exactly is the output from this? I can't get it to run correctly.

Code:
awk '{x[substr($0,9)]++;y[substr($0,9)]=$1}END{
	for(i in x)
printf "%s\nThis Error was reproduced %d times\n",y[i]i,x[i]
}' logfile

What is the output you get?

Code:
zsh 4.3.2% cat file
04:20:00 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping
06:38:08 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to peng

I tried radoulov's script and it works for me. I had a sample log file on my desktop called "logfile.log" with these entries:

Code:
04:20:00 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping
06:38:08 /usr/lib/snmp/snmpdx: [ID 999999 daemon.error] Agent snmpd appeared dead but responded to DING
07:11:05 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping
09:20:00 /usr/lib/snmp/snmpdx: [ID 999999 daemon.error] Agent snmpd appeared dead but responded to DING
10:38:08 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping
11:11:05 /usr/lib/snmp/snmpdx: [ID 999999 daemon.error] Agent snmpd appeared dead but responded to DING

I cd'd to my desktop, and then I used radoulov's script with the slight modification of adding "\" to the end of each line so I could copy and paste it to the bash command line.

Code:
awk '{x[substr($0,9)]++;y[substr($0,9)]=$1}END{\
for(i in x) \
printf "%s\nThis Error was reproduced %d times\n",y[i]i,x[i]\
}' logfile.log

Press return and voila!:

Code:
10:38:08 /usr/lib/snmp/snmpdx: [ID 702911 daemon.error] Agent snmpd appeared dead but responded to ping
This Error was reproduced 3 times
11:11:05 /usr/lib/snmp/snmpdx: [ID 999999 daemon.error] Agent snmpd appeared dead but responded to DING
This Error was reproduced 3 times

Nice job radoulov!
