AMIN(1)                                                       General Commands Manual                                                      AMIN(1)

NAME
       amin - notify writers that you are busy

SYNOPSIS
       amin [-ynesp] command [args...]

DESCRIPTION
       Amin  is  used when you don't want to be written while running a command.  It runs the command given normally.  If your message permissions
       (see mesg(1)) are off, it does nothing much else.  If your messages are on, people writing you with write(1) will be warned  that  you  are
       running that command and will be given the opportunity to change their minds about writing you.

       The  -n  option  may  be used to turn your messages entirely off for the duration of the execution of command.  People writing you will get
       "Permission denied".  The -y option turns your message permissions on for the duration of the execution of the command.  The -e may be used
       after  either -n or -y to indicate that the logins listed in the .yeswrite or the .nowrite files respectively are exceptions to the message
       permissions set.  The default is -s which leaves your message permissions in their original state.  In any case, after the command is  com-
       plete, your permissions will be restored to the original state.

       The  -p  flag causes all telegrams sent to you while the command is running to be saved.  They are displayed as soon as the command is com-
       plete.  If used with the -n flag, writes are refused, but telegrams are still saved.

       If you have designated yourself as a helper, you will still be marked on the finger(1) output as a helper while you are  running  amin  but
       people doing ``write help'' will not be connected to you, even if you have the helper flag set to ``Y''.
