| 00:16:29 | pmcpenguin | hello |
| 00:16:46 | Jayce^ | hey |
| 00:16:55 | pmcpenguin | is the uug meeting being broadcast? |
| 00:17:28 | Jayce^ | no idea... they usually do.. |
| 00:26:34 | Jayce^ | so uug today? |
| 00:26:50 | pmcpenguin | i guess so |
| 00:30:27 | Jayce^ | ok, what's the best way to change a uid/gid, and make sure that all affected files are changed? |
| 00:30:53 | pmcpenguin | why wouldn't they change? :) |
| 00:32:13 | Jayce^ | well, if you just edit the passwd file and their id, then they obviously won't change, they'll just display the old ID.. |
| 00:32:49 | pmcpenguin | oh, i thought you were talking about verbose output from a chown cmd.. :) |
| 00:33:28 | Jayce^ | no, I've got two boxes, which now need to both work on some data on an nfs mount, but the user/group they will do it as are different id's on the boxes.. |
| 00:33:39 | Jayce^ | so I want to move one so the id's are the same. |
| 00:35:03 | levi_ | Do a find on the old uid/gid and do a chown to the new uid/gid? |
| 00:35:34 | Jayce^ | didn't know if there was already a tool that did it. oh well. |
| 00:36:47 | sjansen_ | #uug is live, the meeting has started |
| 00:36:54 | sjansen_ | We're trying to stream. |
| 00:37:37 | sjansen_ | How do I get rid of the _. |
| 00:37:51 | levi | Do /nick sjansen |
| 00:48:25 | Jayce^ | anybody ever use -exec on a find? |
| 00:49:52 | levi | I don't think so. |
| 00:55:00 | sjansen | Of course. |
| 00:55:16 | sjansen | Brain dead commercial unix requires it to do a recursive grep. |
| 00:56:16 | sjansen | Jayce^: what do you want to know? |
| 01:00:12 | han_solo | anyone at the uug meeting here? |
| 01:02:19 | scott | han_solo, #uug |
| 01:03:57 | sjansen | sjansen, #uug |
| 01:08:18 | Jayce^ | crap.. keeps telling me I'm missing an argument.. but I can't figure it out |
| 01:08:28 | Jayce^ | trying to run an -exec on the results of a find (chown actually) |
| 01:09:47 | sjansen | so, say, find '*.sh' -exec chmod o=,g= {} \; |
| 01:14:04 | BZFlag | or find / -name bzflag -type f | xargs chown u+s ;-) |
| 01:14:31 | sjansen | Oops, forgot the / (.) |
| 01:14:55 | BZFlag | the -exec would be executed once per file found. the xargs version would glob it all onto one command line. ie: faster. |
| 01:16:34 | sjansen | Cool. That's one thing that's always bugged by about the -exec. Thanks for the tip. |
| 01:17:24 | BZFlag | problem with xargs is is does not work with progs that need trailing args. like: |
| 01:17:51 | BZFlag | find / -name \*foo\* | xargs scp ... joe@bigserver:/tmp |
| 01:18:05 | BZFlag | there is no way to get the files into the ... space. |
| 01:36:04 | Jayce^ | sorry guys.. connection crapped out there for a minute.. lost part of the discussion.. |
| 01:36:47 | Jayce^ | basically, I have to chown a bunch of files (all with a certain uid) and -exec chown newuser {} wont' work |
| 01:43:54 | sjansen | find / -name bzflag -type f | xargs chown u+s |
| 01:44:05 | sjansen | problem with xargs is is does not work with progs that need trailing args. like: |
| 01:44:10 | sjansen | find / -name \*foo\* | xargs scp ... joe@bigserver:/tmp |
| 01:44:16 | sjansen | (Quoting BZFlag) |
| 01:44:30 | Jayce^ | yeah, the xargs is working for me.. -exec wouldn't though |
| 01:52:25 | BZFlag | -exec should work... |
| 01:52:47 | BZFlag | it will handle filenames with control characters or spaces in the name where xargs might mess up. |
| 01:53:13 | Jayce^ | keeps telling me I'm missing an argument.. |
| 01:53:22 | BZFlag | find / -user foo -exec chown bar \{\} \; |
| 01:55:04 | Jayce^ | ahh, hadn't escaped the semicolon |
| 01:55:17 | Jayce^ | since the manpage didn't do it, I didn't.. |
| 01:55:23 | BZFlag | heh. |
| 02:44:41 | han_solo | anyone use apt-rpm? |
| 02:49:50 | BZFlag | no need on debian. ;-) |
| 02:55:13 | scott | han_solo, so you figure out that riddle? |
| 02:56:22 | han_solo | yeah. 1, 3, 9, 27 |
| 02:56:28 | han_solo | 4 weights |
| 02:56:47 | han_solo | BZFlag: exactly :) apt-rpm has not impressed me yet |
| 02:56:53 | scott | did you think of a way to figure those out? |
| 02:57:00 | scott | like an algorithm |
| 02:59:00 | han_solo | Got the numbers off a website with the solution but no explanation. But afterwards realized the connection |
| 02:59:24 | han_solo | 1 = 3^0, 3 = 3^1, 9 = 3^2, etc. |
| 02:59:49 | han_solo | It's a ternary breakdown -- three choices (left side of scale, right side of scale, excluded) for each weight |
| 03:00:44 | han_solo | for weight x, you just sum powers of three until you have something greter than or equal to x. |
| 03:01:26 | han_solo | unfortunately, once we noticed this, it wasn't worth coding up the backtracking algorithm |
| 03:08:15 | han_solo | wb brailsmt_ |
| 03:09:57 | brailsmt_ | thx... |
| 03:11:44 | scott | han_solo, so what's the deal with ruby, or, why do you like ruby? |
| 03:12:12 | brailsmt_ | ruby is awesome!!! |
| 03:12:32 | brailsmt_ | clean syntax, easy to learn and use |
| 03:12:44 | han_solo | scott: ruby is so extremely relaxing to code in. like zen or something |
| 03:13:02 | han_solo | everything just feels right. oo done right |
| 03:13:24 | han_solo | it's very pragmatic |
| 03:15:07 | brailsmt_ | it is pure OO |
| 03:15:33 | brailsmt_ | its creator organized perl into an OO heirarchy |
| 03:16:11 | brailsmt_ | you can do full blown OO development, or straight procedural, or a mix of the two |
| 03:16:13 | brailsmt_ | you decide... |
| 03:16:25 | brailsmt_ | I find that the language imposes very little on the developer |
| 03:16:29 | scott | is there a site with an index of ruby scripts? |
| 03:16:39 | brailsmt_ | www.ruby-lang.org/raa |
| 03:16:45 | brailsmt_ | i think is the url |
| 03:16:55 | scott | wrong :) |
| 03:17:20 | brailsmt_ | www.ruby-lang.org/en/raa.html |
| 03:27:29 | scott | awful lot of ruby apps |
| 03:30:15 | scott | so what have you guys written in it? |
| 03:30:53 | brailsmt | lots of shell scripts... |
| 03:31:00 | brailsmt | lots of one-liners |
| 03:31:16 | brailsmt | and I have started a gui app too |
| 03:31:29 | brailsmt | I have also written some ruby extensions in C |
| 03:31:30 | han_solo | i've started a gedcom module |
| 03:31:45 | brailsmt | mainly to glue together a C++ app to a ruby gui |
| 03:31:50 | han_solo | and written a script to keep symlinks up to date for my configuration files, which I keep in cvs |
| 03:32:27 | brailsmt | i also have written a script to color code "cvs status" output :) |
| 03:32:54 | scott | see I wish they had an index of one liners |
| 03:33:01 | scott | that's what's really useful |
| 03:33:16 | scott | their great for learning the language |
| 03:33:44 | scott | like checkout http://www.reboltech.com/library/library.html |
| 03:58:56 | han_solo | so, does anyone know how to go from maildir to mbox? |
| 03:59:28 | brailsmt | i went the other way... :) |
| 04:03:45 | scott | gnus can do it |
| 04:04:05 | scott | can't you just cat all the files in one big file? |
| 04:32:11 | han_solo | mutt could do it too, but I'd have to change a few settings. looking for a tool instead. I use maildir, but some things I want to run occasionally want mbox |
| 14:16:16 | CosmicPenguin | is away: Uh, oh.. the weasel got out again... |
| 14:16:19 | CosmicPenguin | is back (gone 00:00:03) |
| 15:00:41 | CosmicPenguin | Anyone here had any dealings with Fatpipe Networks in SLC? |
| 15:33:26 | scott | morning |
| 19:17:34 | Jayce^ | brailsmt: you going to the game tonight? |
| 19:17:58 | CosmicPenguin | Gonna be nice and chilly - just like a college football game should be |
| 19:18:11 | Jayce^ | yeah, hopefully muddy :D |
| 19:18:20 | Jayce^ | cold will help us against hawaii |
| 19:18:25 | Jayce^ | along with the altitude.. |
| 19:18:33 | brailsmt | you bet I am |
| 19:18:37 | Jayce^ | lucky.. |
| 19:19:00 | brailsmt | but I will miss the kickoff and probably the better part of the first half... :( |
| 19:19:06 | Jayce^ | ouch |
| 19:19:26 | brailsmt | but last game I missed the last half of the third quarter and the fourth quarter |
| 19:19:39 | brailsmt | this way I will get to watch the ending, not the begining |
| 20:35:49 | scott | so is ruby good for internet scripts? |
| 20:36:04 | scott | like say, how would you download a webpage with ruby? |
| 20:45:56 | brailsmt | scott: yes, you can use the http module |
| 20:46:18 | brailsmt | you can also write cgi scripts with ruby, as well as embed ruby in html docs ala php |
| 20:48:23 | levi | scott: If you ask brailsmt, ruby is good for EVERYTHING. :) |
| 20:52:13 | scott | looks for the http module docs |
| 20:52:58 | brailsmt | levi: well i wouldn't write a ruby OS |
| 20:53:39 | scott | http isn't even listed in the Library Reference |
| 20:53:40 | brailsmt | scott: you could also do "ruby -e "`wget ...`"" |
| 20:54:38 | scott | or I could just do wget.... :) |
| 20:54:46 | scott | the problem is that's not portable |
| 20:55:53 | scott | hmm, no http in Refrence Manual aeither |
| 20:56:59 | brailsmt | scott: do 'require net' i think it is part of the standard rubyu dist... |
| 20:57:49 | brailsmt | look in /usr/lib/ruby/1.6/net |
| 20:57:57 | brailsmt | you should see an http.rb |
| 20:58:26 | brailsmt | so a "require 'net/http'" should do it |
| 20:58:40 | brailsmt | i am no expert in the http module... |
| 21:23:57 | scott | quick han, how fast can you write a putty script to download a webpage? :) |
| 21:24:06 | han_solo | putty script? |
| 21:24:12 | scott | s/putty/ruby |
| 21:24:18 | scott | :) |
| 21:24:21 | han_solo | about as fast as I can type wget. :) |
| 21:24:35 | han_solo | `wget url` |
| 21:24:40 | scott | a portable ruby script |
| 21:25:12 | han_solo | what exactly does it need to do? |
| 21:25:24 | scott | download a webpage and save it to a file |
| 21:26:46 | han_solo | but needs to work in windows, eh? not cygwin either I suppose? |
| 21:27:42 | scott | well, just needs to be written in ruby not wget :) |
| 21:28:37 | han_solo | well, if I were going for speed I'd actually write it in perl with LWP because I've done that before... but if you want ruby I'm up to the challenge |
| 21:29:16 | scott | I'm just curious how easy something like that is in ruby |
| 21:29:48 | scott | brailsmt said ruby is good for stuff like this :) |
| 21:30:39 | scott | I'd be interested in what it looks like in perl also |
| 21:30:48 | han_solo | perl: |
| 21:31:42 | han_solo | use LWP::Simple; getstore("http://...","filename.html"); |
| 21:33:21 | han_solo | ruby'll take me a few seconds since I haven't done it in ruby yet and don't have a nice oreilly ruby book :) |
| 21:36:13 | brailsmt | scott: yes, ruby is good for something like this, I just don't know what the solution is, and I am working on my homework... you should ask on #ruby-lang |
| 21:36:54 | han_solo | stares in awe. Brailsmt's not at the game yet. |
| 21:37:17 | brailsmt | will be going late |
| 21:37:25 | brailsmt | lack of a babysitter until later... |
| 21:37:29 | brailsmt | :( |
| 21:37:54 | brailsmt | *is* listening to the ksl webcast :) |
| 21:42:11 | han_solo | this does almost what you want (from Net::HTTP docs): |
| 21:42:13 | han_solo | require 'net/http' |
| 21:42:13 | han_solo | Net::HTTP.version_1_1 # declear to use 1.1 features. |
| 21:42:14 | han_solo | Net::HTTP.start( 'some.www.server', 80 ) {|http| |
| 21:42:14 | han_solo | response, body = http.get('/index.html') |
| 21:42:14 | han_solo | print body |
| 21:42:14 | han_solo | } |
| 21:46:33 | scott | so instead of print body you just write it to file? |
| 21:46:53 | scott | looks like perl wins on that test :) |
| 21:47:26 | brailsmt | wrap the whole thin in "File.open("<fname>", "r+") {|f| ... f.print body .. } |
| 21:47:43 | brailsmt | scott: i doubt this is the best way to do it in ruby |
| 21:47:52 | han_solo | well, someone wrote a module to do it real simple in LWP. I could write one and put it on the web and then ruby would be just as good by that measuring stick |
| 21:48:52 | brailsmt | if you want a real nice concise short answer, you ought to ask in #ruby-lang |
| 21:52:36 | CosmicPenguin | or in #perl... :) |
| 21:52:44 | CosmicPenguin | Sorry - couldn't resist |
| 21:52:54 | CosmicPenguin | smacks himself across the head |
| 21:53:10 | brailsmt | joins in the forehead slapping fun |
| 21:53:12 | brailsmt | :) |
| 21:57:34 | Jayce^ | dangit, I missed the perl-ruby discussion again |
| 21:58:44 | scott | too slow joe |
| 22:08:08 | scott | feel free to come up with a more concise version :) |
| 22:23:31 | CosmicPenguin | is away: Uh, oh.. the weasel got out again... |
| 22:38:47 | Jayce^ | ouch, things are getting ugly in provo |
| 22:43:22 | scott | incase any of you care, you'd write the above scripts in rebol like this |
| 22:43:35 | scott | write %file.html read http://foo.com/file.html |
