Timo - Consider me puzzled. There is something missing in the spec for this project - what is the developer trying to do, simply get the log files? If so then rsync, wget, or scp from the commandline, or a gui-based scp tool seem much more useful than any sort of programming solution. Ok, so barring that, I think this seems a perfect use of a scripting language - either perl or any of the various *sh variants. Perl will give you handy, high-level file processing features that will allow the script to zip through a file (even in a .tgz) with very little coding. *sh variants will have similar chunky, high-level features (between tar, find, grep and ls and a few pipes I think there is a simple solution). Either can be readily incorporated into Apache, and with a slight bit more trouble, into your favorite servlet container or (god forbid) IIS. So really the question becomes, what is the developer comfortable with? In terms of professional development I'd say everyone should have some scripting language under their belt. If the fellow has to depend on Java to do the task I'd hazzard to guess he'll spend 3-4 times longer on the solution. If that is the soultion he has to fall back on, send him home with a copy of the Larry Wall Perl book (O'Reilly Press - wtf's the name? Perl in a Nutshell?), or a printout of 'man bash' (though this assumes he has some facility with the cadre of shell commands he'll need - cat, grep, find, tar, ls, ...) and tell him to grind on the solution a bit longer than he would have in order to get the script going in scripting language.

Re: [jug-discussion] Why Jython, or Jelly, or Groovy, or Beanshell or ... instead of perl, or sh script?
I think the issue is that the developer doesn't have remote access to the box; he can only get at the logs through the web. So, scp and rsync are out. wget isn't, of course. :) If it were me... I'd do it in bash using wget. Seems like it would be a one-liner, since you can do it in one line w/ wget, but I'd still throw it in a bash script just so I didn't have to go re-read the man pages on wget every time, and so I didn't have to remember the url, etc. Of course, as pointed out, it all depends on what you're comfortable with. I spend a lot of time in the shell, and have done a fair amount of shell scripting (more than perl scripting, in any event), so... :) Robert Duffy Gillman wrote: Timo - Consider me puzzled.

Groovy would be a decent solution I suspect, but wouldn't you need to layer in HttpClient or something like that to get decent HTTP facilities? Yeah, but in fairness - both ruby and perl need HTTP libraries too. And Commons HTTP Client has a nicely documented API. Oddly, 5 seconds ago on the urbancode anthill list, somebody just sent a link to the beanshell manual (I believe they integrated bsh into Anthill) http://www.beanshell.org/manual/bshmanual.html For somebody with primarily a Java background...it might be an interesting option. Ant could do it, but you'd have to have Java, Ant, and to get looping you'd want ant-contrib as well :) I wondered about the looping...and I certainly don't want to start debating the readability of the build.xml files...

snip Well, shame on you for hiding requirements details (Win32, no CygWin), but wget is available on windoze and using it is simple enough that it can be run from a windoze (excuse the usage) shell - the venerable batch file. If your developer friend lives/works on windoze and can't lash together a one-line batch file he shouldn't be allowed near a computer other than to play games. Also, why on earth would anyone want to handle something as simple as this via something potentially as complicated as Java or Groovy? This is why a real developer has a wide range of tools in his/her kit. And if you find that your available tools don't fit, find and learn one that does. I needed a tool to make flow chart diagrams MY way, and got so frustrated with then-available tools that I learned Postscript and wrote my own tool - a Fortran program that built Poscript output. I've lost count of how useful it has been to have learned Poscript. (Hey, maybe he could write a Postscript program to download and PRINT the logs??!?!)

RE: [jug-discussion] Why Jython, or Jelly, or Groovy, or Beanshell or ... instead of perl, or sh script?
Wow, see... in my defense I did start my post with a complaint that the spec was vague and continued from there. I'd assumed you were talking about allowing the developer some place to drop a server side script (which made the whole thing seemingly pointless because if you can do that, you can probably just access the files via scp, etc.) So let me revise - I'd use bash with the addition of wget. It doesn't matter that you don't have directory index ability on the windoze box - you can munge the URLs based on the file naming pattern. But then there was the new M$ thing someone mentioned... what did you say they're calling it... gonad? -D - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I suspect a subject line with the P-word in it will at least hook folks into reading this... ;-) Problem: developer has access to a website with tar/gzipped log files...archived into folders by year 2005/ and month 01/ 02/ and then the filename has a date in it too - daily. He complains, Wh! I need more than one file, so without SCP access, I have to click click click... Whaaa! I say, Shut up and write a 3 line script to automate the HTTP call... and leave me alone. (I can only imagine what he's thinking about my parentage after that IM. ;-) But this begs a question for the group here... if he asks, What are the three lines? and I decide to do all his freakin' work for him... then, I'd write a little perl script because I've done this in Perl at least a dozen times in my life so it's familiar. I wouldn't grab java because although commons has an http client that's slick, I'd also have to write files and I suck at that in java. But if I make the developer learn how to fish... well, perl might not be apropos given his skillset (i.e. no perl), so I don't know what would be best to suggest to him. So if you were doing this task, how would you approach it? What tool would you use? And more importantly, why? -Timo P.S. there are no bonus points for out of the box approaches like, change the server logging setup or attach a drive share, etc. The point is to focus on the HTTP task and how to do that. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

[Eric would] use Ruby, personally. It'd be much more readable than
the
equivalent Perl variant, almost for sure. The readability factors
into the maintainability too.
Let me break that down a bit...
Can we assume you, Eric, have the experience to write either a perl or
ruby script?
So the choice of Ruby was because you believe that would be more
readable than a perl equivalent, not due... maybe because of more
familiarity with Ruby and less with Perl?
I'm trying to put that gingerly...because, well, my equivelant of your
script looks readable to me, because I know more Perl than Ruby. :-)

You go to scripting with the language you know not the language you wish you had. For me I often write the pseudo code in my head. I often find it looking like one of the scripting languages I know/use and that drives my choice. I may also choose one because it is something that I feel a need to learn. Ruby fits that description right now. I like to term these little languages, some I've used DOS Batch files, rexx sed/awk, perl, ksh, bash, and ruby. Then there is the question of which to suggest to someone of limited scripting use. They may be very computer savoy but have not the experience, or realization, of little languages. For me any would do, but I'd pick the one I knew I would be willing to teach. TR
