Full Discussion: Pulling correct value from Mapfile

Code:
hostname=`grep $client zabbixhosts | cut -f2 -d:`

I tried to simulate your scenario in my linux machine. Assuming that your client variable contains <BaculaServer-fd >.
From the above code, variable hostname contains Server_Bacula if grep is successfull and will contain no value if it fails. Something like this....

Code:
$ cat zabbixhosts
Helpdesk-fd:Server_Helpdesk
Knowledge-fd:Server_Knowledge
BaculaServer-fd:Server_Bacula
Zabbix-fd:Server_Zabbix_1.4.2
 
$ echo $client
sai
 
$  hostname=`grep $client zabbixhosts | cut -f2 -d:` ; echo $hostname
 
$ client="BaculaServer-fd"
 
$ hostname=`grep $client zabbixhosts | cut -f2 -d:` ; echo $hostname
Server_Bacula
 
$ hostname=`grep -w $client zabbixhosts | cut -f2 -d:`; echo $hostname
Server_Bacula

clear_locks

clear_locks(1M) 					  System Administration Commands					   clear_locks(1M)

NAME

       clear_locks - clear locks held on behalf of an NFS client

SYNOPSIS

       /usr/sbin/clear_locks [-s] hostname

DESCRIPTION

       The clear_locks command removes all file, record, and share locks created by the hostname and held on the current host, regardless of which
       process created or owns the locks.

       This command can be run only by the super-user.

       This command should only be used to repair the rare case of a client crashing and failing to clear held locks. Clearing locks  held  by	an
       active client may cause applications to fail in an unexpected manner.

OPTIONS

       -s	Remove all locks created by the current machine and held by the server hostname.

OPERANDS

       The following operands are supported:

       hostname        name of host server

EXIT STATUS

       0	Successful operation.

       1	If not root.

       2	Usage error.

       3	If unable to contact server (RPC).
