Simple script loop question

Hey all. Thanks in advance for any help you can give, hopefully this is an easy one. I want to create a loop to run a simple performance monitor like vmstat and record it to a file, but have very limited scripting skills (obviously).

Starting with this...

date >> /var/log/perfmon.log
vmstat 3 10 >> /var/log/perfmon.log

I basically want it to sleep for 5 minutes using sleep 300, but how do I start the process again (restart the loop)?

Thanks

SA1(8)								Linux User's Manual							    SA1(8)

NAME
sa1 - Collect and store binary data in the system activity daily data file. SYNOPSIS
/usr/lib/sa/sa1 [ interval count ] DESCRIPTION
The sa1 command is a shell procedure variant of the sadc command and handles all of the flags and parameters of that command. The sa1 com- mand collects and store binary data in the /var/log/sa/sadd file, where the dd parameter indicates the current day. The interval and count parameters specify that the record should be written count times at interval seconds. If you do not specify these parameters, a single record is written. The sa1 command is designed to be started automatically by the cron command. EXAMPLES
To create a daily record of sar activities, place the following entry in your root or adm crontab file: 0 8-18 * * 1-5 /usr/lib/sa/sa1 1200 3 & FILES
/var/log/sa/sadd Indicate the daily data file, where the dd parameter is a number representing the day of the month. AUTHOR
