perl limitations vs. bash?

Perl's Wonderful Versatility
Quote:
That versatility is perhaps Perl's greatest strength. I can write any awk one-liner just as quickly and efficiently with perl. I can write a cronjob or the like just quickly and effciently as Shell. I can write a web app just as quickly and efficiently as PHP or Ruby. And I can even write very large scale systems stuff that will run with Java any day.
What other tool has such flexibilty? None. Detractors of Perl will say it tries to be everything and fails at each of it. They never seem to back it up. Perl One-Liners are ofter *better* than awk; perl scripts are almost always better than their BASH equivalent. Perl Web App are often better than their PHP or Python equivalents. etc. And there is massive proof for this.
Moreover. Perl has the most *dedicated and caring community* of all programming languages. As I mentioned before, no language has had as many smart and talented people give so much of their time willingly.
Perl 6 has struggled to say the least and went off track. Perl6 really *did* bite off a bit too much and has lacked a direction. We should all be running it now, in a perfect world. As a result Perl fell off in some important new areas of practical computing like MVC. Too many people care passionately about Perl to let this go on, and are working everyday to fix it.
Frankly, I am extremely disappointed with the moderator's post, in which he engaged in straight up "Linux vs. BSD vs. WIndows" type discussion with no substance and plenty of misplaced condescension. I hope his colleagues will give him a warning for a clear violation his own forum's rules
( I'm just sick to death of hearing Perl sucks and is useless; when it is runs a significant percent of the entire world's financial transactions. ) Barclays, BofA, Credit Suisse, and others all Use Perl; )

I am trying to use the csplit file on a file that contains records that have more than 2048 characters on a line. The resultant split file seems to ignore the rest of the line and I lose the data.

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 AUTHORS
