More and more of what I'm doing is advanced manipulation of data, so I'm using awk/sed/grep/whatever to bend my data and do things with it, I just have this nagging feeling with bash that I'm reaching the end of it's capability (and what it was intended for) and I may need to go some direction. I learned C a little bit and also python, C seemed like you had to write a lot more code (definitely just my opinion, don't know whether it's based on anything) to get a given job done. Python was nice, but I have this nagging feeling it wasn't going to scale down to bash and also up to web apps, at least not yet, though I guess there's a pretty active community hacking it right now. I like Java, but I'm not sure it has the flexibility of perl (another opinion of mine, possibly based on nothing), so I thought I'd possibly learn and use perl for a couple years, get some things done with it, and then look at python/java/whatever again. My theory is that the perl code I'd build could be made to "interface" with whatever language I may choose then, so I wouldn't lose anything, as long as I comment whatever I'm doing in my perl scripts. Feel free to correct any of my assumptions, I don't want to waste a couple of years. The comments so far have been VERY helpful, I appreciate both sides very much, it helps me make a better choice.

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
