hi

what does it mean

>/dev/null 2>&1

on the end of the cron job ?

greetings

it sends both the stderr and stdout steams to a black hole rather than the normal console output. cron will tend to email you any output it gets, which is annoying, so this prevents there being any output at all.

thx , but howto prevent to send an email ?

by appending ">/dev/null 2>&1" to the end of the command.
