Synopsis
openvt
[-c vtnumber] [OPTIONS] [--] command
add an example, a script, a trick and tips
examples
openvt can be used to start a shell on the next free VT,
by using the command:
openvt bash
To start the shell as a login shell, use:
openvt -l bash
To get a long listing you must supply the -- separator:
openvt -- ls -l
description
openvt
will find the first available VT, and run on it the given
command with the given command options,
standard input, output and error are directed to that
terminal. The current search path ($PATH) is used to find
the requested command. If no command is specified then the
environment variable $SHELL is used.
OPTIONS
-c, --console=VTNUMBER
Use the given VT number and not
the first available. Note you must have write access to the
supplied VT for this to work;
-f,
--force
Force opening a VT without
checking whether it is already in use;
-e,
--exec
Directly execute the given
command, without forking. This option is meant for use in
/etc/inittab. If you want to use this feature in
another context, be aware that openvt has to be a
session leader in order for -e to work. See
setsid(2) or setsid(1) on how to achieve
this.
-s,
--switch
Switch to the new VT when
starting the command. The VT of the new command will be made
the new current VT;
-u,
--user
Figure out the owner of the
current VT, and run login as that user. Suitable to be
called by init. Shouldn’t be used with -c or
-l;
-l,
--login
Make the command a login shell.
A - is prepended to the name of the command to be
executed;
-v,
--verbose
Be a bit more verbose;
-w,
--wait
wait for command to complete.
If -w and -s are used together then
openvt will switch back to the controlling terminal
when the command completes;
-V,
--version
print program version and
exit;
-h,
--help
show this text and exit.
--
end of options to openvt.
note
If openvt is compiled with a getopt_long() and you wish to
set options to the command to be run, then you must supply the
end of options -- flag before the command.
history
Earlier,
openvt was called open. It was written by Jon
Tombs <jon[:at:]gtex02.us[:dot:]es or jon[:at:]robots.ox.ac[:dot:]uk>. The
-w idea is from "sam".
