NAME

mingetty – minimal getty for consoles
 

SYNOPSIS

mingetty

[––noclear] [––nonewline] [––noissue] [––nohangup] [––nohostname]
[––long–hostname] [––loginprog=/bin/login] [––nice=10] [––delay=5]
[––chdir=/home] [––chroot=/chroot] [––autologin username]
tty

 

DESCRIPTION

mingetty

is a minimal getty for use on virtual consoles.
Unlike
agetty(8),

mingetty

is not suitable for serial lines.
I recommend using
mgetty(8)

for this purpose.

 

OPTIONS

––noclear

Do not clear the screen before prompting for the login name (the screen
is normally cleared).

––nonewline

Do not print a newline before writing out /etc/issue.

––noissue

Do not output /etc/issue.

––nohangup

Do not call vhangup() to disable writing to this tty by
other applications.

––nohostname

Do not print the hostname before the login prompt.

––long–hostname

By default the hostname is only printed until the first dot.
With this option enabled, the full text from gethostname() is shown.

––loginprog /bin/login

Change the login app.

––nice 10

Change the priority by calling nice().

––delay 5

Sleep this many seconds after startup of mingetty.

––chdir /home

Change into this directory before calling the login prog.

––chroot /chroot

Call chroot() with this directory name.

––autologin username

Log the specified user automatically in without asking for
a login name and password. Check the –f option from
/bin/login

for this.

 

ISSUE ESCAPES

mingetty

recognizes the following escapes sequences which might be embedded in the
/etc/issue

file:

\d

insert current day (localtime),

\l

insert line on which
mingetty

is running,

\m

inserts machine architecture (uname –m),

\n

inserts machine’s network node hostname (uname –n),

\o

inserts domain name,

\r

inserts operating system release (uname –r),

\t

insert current time (localtime),

\s

inserts operating system name,

\u

resp. \U
the current number of users which are currently logged in.
\U inserts "n users", where as \u only inserts "n".

\v

inserts operating system version (uname –v).

 

EXAMPLE

"Linux eos i386 #1 Tue Mar 19 21:54:09 MET 1996" was produced
by putting "\s \n \m \v" into
/etc/issue.

 

FILES

/etc/issue,

/var/run/utmp.
