exit out of a while loop with error
im running a while loop as a file watcher, with incremental counter on the retries..however when the retries reach it's limit i want it exit and echo and error and stop the batch. Im not sure the code i have will do that already...
Here is what i have that works:
#!/usr/bin/ksh
count=0
while [ $count -lt 3 ]
do
count=`expr $count + 1`
echo "Try $count"
RUNDATE=`date "+%h%e"`
filedate=`xyz.txt | awk '{print $6,$7}`
if [ "$Spotfiledate" != "$RUNDATE" ]
then
echo "File's date is $Spotfiledate and today's date is $RUNDATE. They don't match"
echo "I will sleep 30 seconds and try again; 3 tries is my limit"
sleep 30
else echo "Today's file $Spotfiledate is now in."
echo "Sleeping 30 secs to allow it to process."
sleep 30
break
fi
done

snmpwalkoid
SNMPWALKOID(3) 1 SNMPWALKOID(3)
snmpwalkoid - Query for a tree of information about a network entity
SYNOPSIS
array snmpwalkoid (string $hostname, string $community, string $object_id, [int $timeout = 1000000], [int $retries = 5])
DESCRIPTION
snmpwalkoid(3) function is used to read all object ids and their respective values from an SNMP agent specified by $hostname.
The existence of snmpwalkoid(3) and snmpwalk(3) has historical reasons. Both functions are provided for backward compatibility. Use snm-
prealwalk(3) instead.
PARAMETERS
o $hostname
- The SNMP agent.
o $community
- The read community.
o $object_id
- If NULL, $object_id is taken as the root of the SNMP objects tree and all objects under that tree are returned as an array. If
$object_id is specified, all the SNMP objects below that $object_id are returned.
o $timeout
- The number of microseconds until the first timeout.
o $retries
- The number of times to retry if timeouts occur.
RETURN VALUES
Returns an associative array with object ids and their respective object value starting from the $object_id as root or FALSE on error.
EXAMPLES
Example #1
snmpwalkoid(3) Example
<?php
$a = snmpwalkoid("127.0.0.1", "public", "");
for (reset($a); $i = key($a); next($a)) {
echo "$i: $a[$i]<br />
";
}
?>
Above function call would return all the SNMP objects from the SNMP agent running on localhost. One can step through the values with a
loop
