>/dev/null

Maybe it's an stupid question but remeber... I'm Junior.. I use command line to run programs, and some of them gives a lot of information when, for example, you open a window or other actions. That's really bad because my terminal gets full of unwanted messages, so I use "bin file & >/dev/null"...

KUVERT_SUBMIT(1)						   User Commands						  KUVERT_SUBMIT(1)

NAME

       kuvert_submit - MTA wrapper for mail submission to kuvert(1)

SYNOPSIS

       kuvert_submit [sendmail-options] [recipients...]

DESCRIPTION

       Kuvert_submit submits an email either directly to sendmail(8) or enqueues it for kuvert(1) for further processing.  kuvert_submit should be
       called by your MUA instead of your usual MTA to enable kuvert to intercept and process the outgoing mails. Please see your MUA's
       documentation about how to override the MTA to be used.

       Kuvert_submit transparently invokes "/usr/sbin/sendmail" directly if it cannot find a ~/.kuvert configuration file, or if the -bv option is
       given. Otherwise, it enqueues the email in the queue directory specified in the configuration file.  If that fails or if the configuration
       file is invalid, kuvert_submit prints an error message to STDERR and terminates with exit code 1.  On successful submission, kuvert_submit
       terminates with exit code 0.

       Kuvert_submit also logs messages to syslog with the facility "mail".

OPTIONS

       If it runs the MTA directly then kuvert_submit passes all options through to /usr/sbin/sendmail. Otherwise, it ignores all options except
       -f and -t (and -bv which triggers a direct sendmail pass-through).

       -f <emailaddress>
	   Sets the envelope sender. Kuvert_submit passes this on to kuvert.

       -t  Tells an MTA to use the recipients in the mail instead of any commandline arguments. If -t is not given then kuvert_submit passes the
	   recipients from the commandline on to kuvert.

FILES

       ~/.kuvert
	   The configuration file read by kuvert and kuvert_submit. If not present, kuvert_submit calls /usr/sbin/sendmail directly.

       ~/.kuvert_queue
	   The default queue directory.
