If you are using Linux, you can check out the 'colour-ls' text in HOWTO/mini -
while specifically written for ls, it contains a BASH script and a table that
shows how to display ANSI colour sequences.
If you are on another system, the info should still be relevant; you can find
the HOWTO:s in html format through the Linux Documentation Project on
sunsite.unc.edu. Hope this helps (and please mail me with your

This question assumes that all the languages (!) can be assembled
into one long ordered list. But I don't think that models the
real world accurately. Really, you want a tree.
Perl is at the root node.

When you get to the level of "worst" there are hundreds of
languages, none of which I would prefer to another.

Hmmm. Since I mentioned 'my VC++ or VB compilers...', perhaps you think
I didn't know what VB is? ;-) Actually VB is a GUI development system
which supports a dialect of BASIC for writing what amount to macros,
and which supports some OO concepts. BASIC is a free-standing, purely
procedural language, not embodying any OO concepts. C and C++ are
different languages, after all, are they not? In other words, VB
*includes* a *highly modified subset* of BASIC. VB is *not* BASIC. And
if you think VB is 'very similar to QuickBasic', you couldn't possibly
have used both. It is true that some of the syntax is virtually identical,
but QuickBasic and VB are far more different as a whole than say, Pascal
and ALGOL. The user interfaces are *totally* different, and way programs
are structured is *totally* different. If you are still unconvinced, just
write a minimal 'Hello World!' program in both, print the entire source of
each, and examine them. Very little similarity, eh? The text "Hello
World!" itself is the only part which is even remotely the same. 8-)

I did follow the old thread with your question but I hope someone
recommended the "Art of Programming" by Donald E. Knuth.
Unfortunately it is quite expensive here, so I read it only in public
libraries. It has a lot of beautiful ideas and views in it.

I think you overestimate the value of schools and universities.
Force yourself through the Pascal book. Esspecially if it is one by
N. Wirth. After something like that (Modula-2 in my case) for me the
only way was doing "it" on my own. I cannot read computer books
without doing programming in parralel(If I try I fall asleep).
Try to get a Pascal compiler (old Turbo Pascal for Dos) if Pascal is
your language of choice. I think there are now public domain clones
for Dos/Unix availiable.) Try to develop some basic stuff on your own
(like sorting an array). Read how others do sorting. Try to understand
it. Program the basic exercises with linked lists and trees. Avoid
like plague at this stage of learning all grafical userinterface
stuff.

Hi,
I'm finding the way to hide the source code of my
perl scripts. I have downloaded some software and
tested them on my machine. Could anybody share with
me your experience on this issue.
Here is what I have tested:
- ShroudIt! (evaluation version from www.lnk.com).
The program indeed shrows the perl code, but it also
it makes the program unable to run.
- perl2exe (evaluation version from
www.demobuilder.com). This program convert my perl
script to .exe file. But then the file size become
too big. A 11 KB perl code could grow to 0.5 MB .exe
- perl compiler version alpha 3 from www.perl.com
which convert perl to C. I have not yet finished with
this test.
I wonder if there are other software which I can try.
Thanks,

-- It sounds like you've done some research. But, after
much fear the customers would run off with our source
and develop it themselves, and many conversations and
attempts to turn Perl into C and compile it, our conclusion
was the same as the FAQ:
"If you're concerned about people profiting from your code, then
the bottom line is that nothing but a restrictive license will give
you legal security. License your software and pepper it with
threatening statements like "This is unpublished proprietary
software of XYZ corp. Your access to it does not give you
permission to use it blah blah blah." We are not lawyers, of
course, so you should see a lawyer if you want to be sure your
license's wording will stand up in court."
- "How can I hide the source for my Perl Program?"
- From PerFAQ(3)
Now all you need to do is convince your manager, and you're

Some people code in Perl for work. And it is sometimes necessary to
distribute these sniplets of perl code - not so many companies are
willing to share their code for free.
I'm all for GPL and free (as *free*, not just without cost) software,
but sometimes it is just necessary to distribute code without
revealing it.
Not that it makes any difference, but IMHO so called 'core stuff'
should be always distributed under GPL. With 'core stuff' I mean all
the software needed for developing specialized software, like in Unix,
the kernel itself and basic utilities (cat, ls, command interpreter
and so on).

You can use read to read records from a file and unpack to unpack the
records into perl variables - as long as you know the layout of the
structures (including any packing) The perfunc man page describes both
read and unpack (but the templates used for unpack are described under
pack)
Hope this helps,

A simple trick to find out which version of a module you have
installed is to run something like:
$ perl -MLWP\ 999
LWP version 999 required--this is only version 5.32.
BEGIN failed--compilation aborted.

MSIE 4.01; Windows 95)" while the Win311 comes up as "Mozilla/4.0

Message-Id: <19sk1.1$HS4.30@eagle>
Problem: I need to redirect browsers based on their OS - to one place if it
is a 16 bit win system to another if it is a 32 bit system. The enviro
variables I have found for Win32 Perl only pull the servers variables and
not the clients. The problem is that we are using IE4 univesally in our
company but some are on win311 and some on win95/NT.
I noticed that if i use a browser redirection with the
$ENV{'HTTP_USER_AGENT'} one browser comes up as "Mozilla/4.0 (compatible;
MSIE 4.01; Windows 95)" while the Win311 comes up as "Mozilla/4.0
(compatible; MSIE 4.01; Windows 3.1; CRHC Intranet)" but I am not sure how
to write the syntax for a browser redirection based on this.
ANy help will be greatly appreciated and I may be able to recipricate as
well! Thanks in advance.
I am using the latest build of Active State's win32 Perl (isapi) on IIS4 -
(works pretty good so far).

Message-Id: <kl6af71lkdo.fsf@sgca02.cern.ch>
Hi
Is there a way to make query the system resources, and by
that I mean the actual hardware resources such as #cpu's,
memory, swapspace and stacksize ?
I need to do this on AIX, Digital UNIX and Windows NT,
so either I need some standard way to do this, or a specific
way for each platform.
Can anybody help me with this, or maybe just point in some
direction ??
Thanks in advance

Subject: Reference parameters and scripts
Message-Id: <6mt6vt$6t4$8@nz12.rz.uni-karlsruhe.de>
Hi!
I am still busy trying to pass an already opened file handle (such as
STDIN) as a parameter to a function. This is how my test code advanced
so far:
mh@palandt:/home/mh/wd2 > cat test.pl
#!/usr/bin/perl -w
use strict;
sub mytest
{
my ($FH, $Array) = @_;
@$Array = <$FH>;
<do something with @$array>
}
my @ThisArray;
mytest(STDIN,\@ThisArray);
<do something else with @$array filled by mytest()>
This works fine as long as I don't "use strict;" in my code. When I
use strict, perl complains about the bareword STDIN that is illegal
with strict subs enabled. I probably need some syntactical sugar to
get that to work. What am I doing wrong?
Any hints will be appreciated.
Greetings
Marc

Exactly. You need to pass a reference to a typeglob:
mytest(\*STDIN, \@ThisArray);
should work fine and pass 'use strict;'.

Can we see some samples of your input data? From looking at your regex, it
must be in the form:
*C** a.......b....... x y
or
*C** a.......b....... xy
or
*C** a.......b....... x
or
*C** a.......b....... y
If you ever only have a line with module_mode but no module_type, which,
based on your regex, is possible, it will get thrown into the wrong variable
($module_type). Again, this would be much easier if we could see samples of
your input data.

perlre is your friend in this case, available as standard perl documentation:
s/1/2/g
Replaces 1 with 2. Funny enough, the perlre page doesn't seem to explicitly
state what g does, but I think I read between the lines that it is the global
match operator.
If you are interested in regular expressions: They are based on work done by
Henry Spencer's regexp routines. And for a broader overview you could go to
http://www.exoterica.com/white/cma/ on content model algebra.

I had the same problem, this comes from the Microsoft site and it works:
To configure PERL script mapping
WARNING: Using Registry Editor incorrectly can cause serious,
system-wide problems that may require you to reinstall Windows NT to
correct them. Microsoft cannot guarantee that any problems
resulting
from the use of Registry Editor can be solved. Use this tool at your own
risk.
1.Start Regedt32.exe and open
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\W3SVC\Parameters\ScriptMap
2.Click Add Value from the Edit menu.
3.The Value Name is .pl
4.The Data type is REG_SZ.
5.The String value is <the full path to perl.exe>\perl.exe %s %s
6.Restart the WWW service.
Hope this helps,
Cheers,
Guillaume.

I usually work from a printed 5.002 copy of the documentation (I have
later ones online) and this includes the use of system BLOCK LIST. All
that seems to have been added is an example - the old documentation
still mentioned that the use of this syntax forced LIST to be treated as
multi-valued (and hence no shell-escapes).

I guess that at heart of your program there is some regular expression. If this
is true, then you will find the perlre page most useful. In there you will also
find an option for the regular expression to look case insensitively (ouch,
freestyle English again!).
/SoMeThInG/i will also match sOmEtHiNg.

I am not saying that referring a new user to the FAQ is insulting. I am
referring to other comments made by people on this group, either in
private or as a public post, such as, "That question is so stupid I can't
even begin clarifying it for you, so i am not going to".
That type of a response helps no one, and really just wastes the time the
person given and recieving the help.
