Or what I keep handy in the top of my cron script #################################################################### # syntax example # #minute (0-59), # #| hour (0-23), # #| | day of the month (1-31), # #| | | month of the year (1-12), # #| | | | day of the week (0-6 with 0=Sunday)# #| | | | | commands # #30 01 * * * /home/jim/bin/cleartmp # #################################################################### So I would guess it would be * 8 * * 0 /your/script_fn_here
