Top Forums UNIX for Dummies Questions & Answers Running set options from the command line and bash command Post 302542420 by Straitsfan on Wednesday 27th of July 2011 02:06:45 PM

Corona --

What I meant was on the command line you can use set [option as a word] to turn it on or off, and then run a script to see the results. But what I was wondering is how to use the other option on the command line. I tried

set -v testscript

and nothing happened (it works fine if I type set -o verbose testscript, for example.] If I tried the scriptname first and then the one letter option, I get an error message. So I was confused as to how to use just the one letter option on the command line -- or is that how it's done when you use the command bash?

I hope that's clearer.

And what exactly does the command 'bash' do?

OPENVT(1)							     Linux 1.x								 OPENVT(1)

NAME
openvt - start a program on a new virtual terminal (VT). SYNOPSIS
openvt [-c vtnumber] [OPTIONS] [--] command 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; -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 com- mand 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. 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 HISTORY
Earlier, openvt was called open. It was written by Jon Tombs <jon@gtex02.us.es or jon@robots.ox.ac.uk>. The -w idea is from "sam". SEE ALSO
