Process starting with their output redirected to /dev/null? I know
it is used a lot in batch files where you do want any of the version
or identification output of a program - just the return code and
whatever the program does. It is also sometimes used to send any
error output to the bit bucket.
Another common use is in cron jobs - you only want output if there
is an error, or any output to be output through syslog. Normal
program output would generate an unwanted e-mail message from the
cron job.
