<0> You're ***umed to have at least SOME grasp of the basics before you ever come here.
<1> !learn FAQ The FAQ is not intended to be a tutorial, or to teach you the basic syntax of bash.
<2> OK, bronze
<1> !FAQ
<2> No matches found at http://wooledge.org/mywiki/BashFaq
<1> urk!
<3> you broke it now.
<1> !forget FAQ
<2> OK, bronze
<0> !faq 2
<2> http://wooledge.org/mywiki/BashFaq#faq2 -- How can I store the return value of a command in a variable?
<0> You can't make it forget an internal command.
<1> greycat: wast doing that.
<4> i wanna that while that runs one times withouth checking the condiition and then check that and exits if that true
<1> *wasn't
<4> but i don'T know that's name
<1> "until
<0> it's far easier just to set the variable so that it's always true the first time around.
<1> do { some actions } until <condition>
<4> aaah thx.
<0> bronze: wrong language.
<1> *Note : syntax not included
<0> bash's until is just "while !"
<4> yes i know
<1> greycat: That wasn't any language. :-)
<4> i'm in a howto but there is 80 loops
<0> bronze: it was very close to C.
<1> ja.
<0> MetaMorfoziS: are you trying to validate user input? Or what?
<1> but no semi colons and lots of psuedo english
<4> yes.
<5> I got proctools installed from sourceforge, added a little section to http://wooledge.org/mywiki/ProcessManagement. but I can't get the man pages to install. do man pages have to be generated separately?
<0> while true; do echo ....; read whatever; [[ $whatever = .... ]] && break; ....; done
<0> That's the simplest thing.
<3> it seems abstract terms don't make much sense to people anymore. They always need an example to understand.
<0> what the hell's proctools?
<5> ;)
<4> who asked for example?
<5> proctools is the sourceforge package to give us lowly mac os x users the pkill command
<1> heh.
<4> i was have working the code before you asked "[18:11:48] <0> MetaMorfoziS: are you trying to validate user input? Or what?"
<0> MetaMorfoziS: then why are you asking for help?
<4> i'm only asked the name of "until"
<0> bash does NOT HAVE an "until" command that works like C's.
<4> then you executed bronze about the syntax
<0> it has an "until" that works like "while !"
<0> lhunath: well, it's not very well written, but I doubt anyone's got the urge to redo it (or the Mac OS required to attempt a build...)
<6> Since when does C have until?
<0> doesn't it have a "do...while" or something?
<0> God, it's been WAY too long...
<6> You're thinking perl, perhaps
<5> lunath: it may be better to start with a poorly written man page than to have none at all :)
<0> I'm thinking of that atrocity that bronze posted which just HAPPENS to work like what meta* wanted, which is NOT possible in bash, but for which I already gave alternatives.
<7> c++ has a do-while loop
<1> greycat: it was a thought ballon only
<3> djwonk: I personally find the installation howto of proctools a tad beyond the scope of the process management page.
<0> Three of them, as I recall.
<5> lunath: should I create a separate page, then?
<5> lunath: and save space on the process management page?
<0> You shouldn't have to create ANYTHING. It should come with a README and/or an INSTALL file which tells you what to do.
<3> djwonk: not my place to tell. But I would have stuck to a link as reference.
<3> djwonk: and in case you were wondering why my name isn't autocompleting, it features an h, after the first l.
<8> what's the name of the utility that splits one pipe into two??
<9> tee?
<8> right, thx al ot
<4> i have three until's under each other
<4> and only the first runs down, then the script exists
<4> exits
<10> is there a way to enalbe the alt + . bash shortcut in mac os x?
<10> greycat, last comand argument
<0> you mean $_ ?
<10> greycat, $! I think
<10> greycat, anyhow, its a very useful shortcut, brother
<0> $! is the last background job's PID
<10> ah right
<0> $_ is the last argument of the previously entered command
<10> ok
<10> well alt . is the shortcut
<10> now bow before me
<0> sounds like you've got some customized stuff in your inputrc
<10> greycat, yes I am THAT Good
<10> its standard bash greycat
<10> on os x and debian
<0> So it's standard Debian and OS X.
<10> what do you use?
<0> Alt-. isn't even a BYTE, so you can't actually TYPE it on a terminal, which means it cannot be standard bash in any sensible meaning of that phrase.
<0> Sorry... care to guess again?
<0> So, OK, it's implemented in Debian IF you are in emacs mode.
<7> works in cygwin
<10> in your face cat
<0> Whatever.
<10> panda bear
<0> By the way, typing "set -o emacs" in a bash window (rxvt) on HP-UX 10.20 does NOT enable your Alt-. key binding.
<0> So, I suggest you examine that inputrc file as I mentioned earlier.
<10> ooooohhhhh
<10> who the hell uses hp ux?
<10> i mean what bash version is that?
<3> grin.
<0> 3.1.17(2)-release
<0> HP-UX imadev B.10.20 A 9000/785 2008897791 two-user license
<10> you just raised the steaks
<0> Obviously I compiled bash myself; it doesn't ship with HP-UX (and certainly wouldn't have been version 3.x back in 1995-ish when 10.20 was released.)
<0> Steaks? Is that what we're having for lunch?
<10> whatever you want honey
<3> betting over lunch meals.
<0> I'm still trying to figure out why he thinks I'm holding steaks up in the air.
<11> maybe he thought you were a farmer
<12> Quick newbie question here: how do I format output from multiple commands nicely? ie: echo "$filename"; cat $filename | wc -l" I'd like that output to all appear on one line
<0> echo -n "$filename: "
<0> better still: wc -l "$filename"
<3> or echo "$filename: $(wc -l "$filename")"
<3> !uuoc
<12> greycat: thanks, that does the trick. How would I do that with output from programs that *do* always use a newline?
<2> Useless Use of Cat (cat foo | grep bar). See <http://www.ruhr.de/home/smallo/award.html>;.
<10> watch the quotes
<0> if you're going to do that, use wc -l < "$filename" to suppress the filename at the end.
<0> krang: show me WHAT program you're talking about.
<0> and remember that $() chomps off all trailing newlines.
<10> show me the money
<12> greycat: Ah, perfect, thanks!
<10> cocaine is bad for you. You have to see the BASH I coded
<11> or the IRC TEXTS you typed
<10> panda bear!
<10> I missed you more than my bash shortcuts in Os X
<10> JACK BAUER IS BACK
<13> Not another 24 fan ;_;
<10> I hate these glossy screens on the macbooks, with a dark bg I get to see myself
<13> Not a pretty site.
<13> eh, sight.
<14> Kiefer has finally forgiven Julia for cheating with Jason!
<10> not at all
<14> (Sorry, had a little celebrity attack, there.)
<15> greets everyone
<15> I have a long file of user data, and I need to print out the column only with email addresses. The problem is that it's not always in the same column.. is there a way to get only the email addresses?
<4> how can i copy a link?
<0> you want the copy also to be a link?
<4> no.. moment i can't speak..
<0> if you want the copy to be a regular old file, just use cp
<4> so i ahve a path that is ends in alink if i just cp it, it cp-s the link
<4> not the folder
<0> oh, it's a symlink to a DIRECTORY?
<16> vaccine, just how 'long' is that file?
<13> vaccine: You could maybe use a *gasp* regular expression...
