Running set options from the command line and bash command
I'm reading about debugging aids in bash and have come across the set command. It says in my little book that an addition to typing

set [option]

you can also use them "on the command line when running a script..." and it lists this in a small table:


set -o option Command Line option
noexec -n
verbose -v
xtrace -x

I know how to set the options in the first column, but how are the options in the second column used? I've tried typing the name of the script followed by the option and vice versa, but only the results of the script are displayed on the screen. Can someone tell me what I'm doing wrong, or am I misunderstanding something?

The book I'm using is "Learning the bash shell" if that helps, 3rd edition, page 222 halfway down under "set options"

Also, on the following page, when illustrating how to find a bug in program, it lists the command

bash -v scriptname

when looking for the bug.

what does the command bash do exactly? I haven't encountered this command before in this context and am not sure what's going on.

xsil2graphics

XSIL2GRAPHICS(1)					User Contributed Perl Documentation					  XSIL2GRAPHICS(1)

NAME

       xsil2graphics - generate scripts to load xsil output data files

SYNOPSIS

       xsil2graphics [options] <xsil_file>

DESCRIPTION

       Utility program bundled with xmds, used to generate scripts that load simulation output data into either matlab (http://www.mathworks.com)
       or scilab (http://www.scilab.org), which are then used to manipulate the results further if necessary and then to present the results
       graphically.

       Matlab

       To generate a matlab m-file, from the xsil file data_file.xsil use the command:

       bash$ xsil2graphics data_file.xsil

       or

       bash$ xsil2graphics --matlab data_file.xsil

       Then at the matlab command prompt:

       >> data_file

       Scilab

       To generate a scilab script file, from the xsil file data_file.xsil use the command:

       bash$ xsil2graphics --scilab data_file.xsil

       Then at the scilab command prompt:

       --> exec('data_file.sci')

OPTIONS

       -m, --matlab generate matlab m-file script to load data from the xsil data file (the default option)

       -s, -scilab generate scilab script file to load data from the xsil data file

       -o, --outfile <out_file> specify an alternative output script filename to the default which is the input xsil filename with the .xsil
       extension changed to either .m for the matlab m-file or .sci for the scilab script file

EXAMPLES

       bash$ xsil2graphics nlse.xsil

       Generates the output nlse.m to load the data into matlab

       bash$ xsil2graphics -m nlse.xsil

       Also generates the output nlse.m but explicitly sets matlab to be the output format

       bash$ xsil2graphics --scilab nlse.xsil

       Generates the output nlse.sci to load the data into scilab

       bash$ xsil2graphics --outfile nlse_new.m nlse.xsil

       Generates the output nlse_new.m to load the data into matlab
