help with if clause in bash script
hey guys,

I am trying to get some statistics from a DHCP server, like counting the number of DHCP Discovers from a specific MAC address. The script should count the number of DHCP Discovers and output it, otherwise if it cannot find any , it should output the MAC address and "0".

The first clause I am pretty sure it works, I did test it. The problems when I add the if clause.

I did the script like this :

cat /var/log/messages.2.gz | zgrep 192.160 | zgrep "DHCPDIS" | zgrep 0012DFCFC492 | cut -c7- | cut -d ' ' -f5 | sort | uniq -c | sort -rn >> /my_scripts/LOGS/dhcp_test
if [ " cat /var/log/messages.2.gz | zgrep 192.160 | zgrep "DHCPDIS" | zgrep 0012DFCFC492 | cut -c7- | cut -d ' ' -f5 | sort | uniq -c | sort -rn " -lt "1"];
then echo "0012DFCFC492 0" >> /my_scripts/LOGS/dhcp_test
fi

I am getting this error :

./test.bash: line 2: [: missing `]'

What am I doing wrong ?

Thanks in advance!
