Crontab syntax looks like this:
30 5 * * * /usr/you/home/runme.pl
The first number is the minute of the hour that the command will be executed.
The second number is the hour of the day that the command will be executed.
The third number is the day of the month that the command will be executed.
The fourth number is the month of the year that the command will be executed.
The fifth number is the day of the week that the command will be executed.
The last part is the server path where the script to be run is located on the server.
The syntax above would execute runme.pl every day at 5:30AM.
For example, * * * * * would mean every min
and 0 0 * * * would mean at midnight.

This will take you to the directory where you uploaded the crontab file.
4. To execute your crontab file use the telnet program and type this:
