>/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"...

sendmailconfig

SENDMAILCONFIG(8)					      System Manager's Manual						 SENDMAILCONFIG(8)

NAME

       sendmailconfig - configure sendmail for Debian systems

SYNOPSIS

       sendmailconfig [--no-reload]

DESCRIPTION

       sendmailconfig is used to simplify the configuration of sendmail(8) for use on Debian systems.

       In  the	simplest  case,  you  may  run	this program to (re)configure sendmail for your Debian system at any time. It will modify the file
       /etc/mail/sendmail.mc in order to create a working sendmail configuration which will be written to the file /etc/mail/sendmail.cf.

       For advanced configurations, you can modify the sendmail.mc file before generating sendmail.cf. Future invokations of  sendmailconfig  will
       preserve these changes provided they are made at the end of the file.

       Normally  sendmailconfig  will  ask  if	you want to reload sendmail after making changes to its configuration. The --no-reload option will
       avoid this question.

FILES

       /etc/mail/sendmail.mc
	      sendmail m4 input to generate sendmail.cf

       /etc/mail/sendmail.cf
	      actual sendmail configuration file

       /etc/mail/sendmail.cw
	      names for which we will accept mail in the standard configuration

       /etc/mail/sendmail.ct
	      names of trusted users in the standard configuration
