I like writing small scripts in perl as well, but perl really is a write-only language - they keep adding syntax and operators to provide 1,647 different ways to do the same thing so whatever perl code you are trying to read was almost certainly written by someone who knows and loves a completely different subset of the language :-). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I am not even good at Bash. :-) perl comes with an extensive amount of documentation. Try 'man perl' for an overview. And it is a language that is easy to get started with. I tried it and I just can't get the hang of it. 'man perl' confuses me more then that it helps me. It is me that can not do it. Some people are good at perl, I am good at thinking up solutions for people who know even less about SUSE or Linux then I do. I am also a person who just has to type in and see what happens, instead of reading and realy learning it. I never could learn from a book and I doubt that will change. So what I mostly do is social engineer my code together. :-) e.g. you see a HOWTO like http://en.opensuse.org/Making_a_DVD_from_CDs#Manually_build_a_DVD_from_the_CD-Set and that you put in a bash script. Then I started to put in a for for the booting and copying and started to make it more generic. A bit later added some features. And all this thanks to the many people contributing and sending me correcting code. Thanks. houghi -- Nutze die Zeit. Sie ist das Kostbarste, was wir haben, denn es ist unwiederbringliche Lebenszeit.

Say just rewrite a C program 1:1 in perl, upto C's for and while statements, and your convention for translation a case cascade. I don't rewrite C, becaue I can't do C. Say just rewrite a shell script using awk. I can't do awk either. In both cases, perl's syntax allows you to retain most of the syntactic and semantic structure of say C or AWK. Perl even supports awk's BEGIN blocks, so you've to peek that the #! line on top to be sure you're reading perl... That is nice. Well, if you know what people are talking about. I don't know what a BEGIN block is. Or lisp. Perl has lists, and map (plus shortcuts like pop,unshift, grep, ...). cdr is missing, but you just use shift. Chnese to me. I don't do Lisp. Lambda objects are function refs, etc. Everything's there, except the visual appeal of being able to have a syntactically necessary lines finishing with a block of 20+ closing parantheses. Sounds interesting. Although I have no idea what it means. Saner persons than RMS however cite this as the sole reason to avoid lisp :). I heard him speak unfortunatly at FOSDEM. Everybody is saner then RMS. After listening to him I had an urge to walk into a store, buy XP Pro and install it. perl baby talk's fine. Or a decide later an idiomatic open or die stanza followed by a schwartzian transform-resort of file data. What on the commandline would be something like map|sort|map. Functional programming and lisp also comes to mind. Uhm. OK. (Or as they say in Germany Ich verstehe nur Bahnhof. - obfuscation is easy. also unintentional obfuscation. So self-discipline is a bit more important than in more restrictive - or crippled - environments elsewhere. For me reading somebody elses bash code looks already as if it was obfuscationized code. - perl5 has support to create your own OO-Language on top of it. However it is decidedly no object-oriented language. [ok, this is opionated, but unless one has a SINGLE RIGHT one way to use e.g. inheritance and overload my parent's functions within a well-defined oo interface, the language just isn't oo. Just like C. Not if every one develops his/her own OO inheritance conventions. Heck, you can never be sure of object itself: does the modul I'd like to reuse use a scalar or a blessed hash as base for his objects?? Saying1 vs. Perl5 = 1 : 0, Perl5 standing, but with hole shot in foot.] Python wins here, as well as that rumoured new language to be called perl 6. being able to _BREAK_ any perl5 syntactic rules. Well, I don't do Python either. Then I started to put in a for for the booting and copying and started to make it more generic. A bit later added some features. Which is just fine when using perl for small, single-authored scripts... Sure it is, if you know what you are doing and know perl. I am sure my code would be better written in perl. If I would understand perl, I would have just taken create_package_descr and edited it. It would have been a lot easier, because makeSUSEdvd is nothing more then a wrap around it. It would be also a lot easier to include tagmedia in it, instead of leaving it as a seerate program. However, I am not a programmer, nor will I ever be one. If at most I am a mediocre scriptwriter. Again, perl will be a great langage, it is just not for me. houghi -- Nutze die Zeit. Sie ist das Kostbarste, was wir haben, denn es ist unwiederbringliche Lebenszeit.
