To get prompt, use this...


Code:
$ cat test.sh
echo "enter something"
read line
echo $line
 
$ sh test.sh
enter something
while read
while read

So is the purpose of the while loop to just keep reading each line within the while loop until something causes it to come out or stop e.g. an exit statement

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 AUTHORS
