  • zsh: command not found: ls

    - by ABach
    I'm having a rather strange problem with zsh. When I start up my shell, everything - functions, environment vars, aliases, etc. - all work fine. I've created the following function and sourced it in zsh: clean() { for i in /tmp/* do echo $i done } Running clean in the terminal works as expected, in that it prints out all the files in /tmp/. Afterward, however, trying any command - for example, ls - produces this: zsh: command not found: ls I have several other functions that work just fine, which leads me to believe that somehow, that loop is causing the problem. At any rate, this is very frustrating and I would sincerely appreciate the community's eyes. Thanks!

  • Interacting with RESTful API's via Javascript?

    - by Alex
    Hi there, to start off, I know C++, C#, Python, some Ruby, and basic Javascript. Anyway, my question revolves around how to interact with RESTful API's via Javascript. I haven't been able to find any good examples on various websites, and so I've come here. So my basic question is: How do I interact with RESTful API's via JS? And where can I find out how to implement OAuth in JS? I know how to get my keys and such, just not how to actually code them in. Below is an example of a twitter API status update run from my MAC terminal with curl: curl -u username:password -d "my tweet" http://api.twitter.com/1/statuses/update.json How can I implement this in Javascript (preferably with OAuth authentication)? This would at least start me going in the right direction. Thanks so much!!

  • Context free grammer

    - by Evil
    Hello. I have this problem where i need to convert the following CFG to CFG in CNF. S- ABa A- aab B- Ac I know the steps are as follows. 1) Remove epsilon transitions - Done 2) remove unit productions 3) convert to CNF by: 3.1] introduce a new non terminal for each term 3.2] replace terminals in the productions rules with the new nonterminal 3.3] introduce new nonterminals to reduce the length of the right side of each production i'm a bit confused on how i would do that with the problem above. Mostly i am confused on step 2 and unit productions. If i could get some help or perhaps a link to a good tutorial that would be most helpful.

  • Xcode & passing command line arguments

    - by Brisco
    I just started working with C & Xcode and I've run into a little difficulty. All I want to do is read a file from the command line and see the output in the terminal. I think my problem lies with the path to the file that I want to read in. I'm using a Mac and the file is on my desktop, so the path should be Users/myName/Desktop/words.txt. Is this correct? This is my code: #import <Foundation/Foundation.h> int main (int argc, const char* argv[]){ if(argc == 1){ NSLog(@" you must pass at least one arguement"); return 1; } NSLog(@"russ"); FILE* wordFile = fopen(argv[1] , "r"); char word[100]; while (fgets(word,100,wordFile)) { NSLog(@" %s is %d chars long", word,strlen(word)); } fclose(wordFile); return 0; }//main

  • Why is ContextConfiguration location different in idea and eclipse

    - by jakob
    Hello experts. In my team we work both in Eclipse and Idea. That works pretty good, except for one minor issue that I can't figure out how to solve. When setting the ContextConfiguration location in our tests and running them inside Eclipse everything works like a charm: @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:src/main/webapp/WEB-INF/applicationContext.xml" }) But in my Idea env I get "could not find applicationContext" error. I need to set the location like this(project name is services): @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:services/src/main/webapp/WEB-INF/applicationContext.xml" }) The project structure is like this: parent.pom with two child poms: services.pom and other.pom. When running the test in the terminal from the service project like this: mvn -Dtest=com.mytest.service.somepackage.TheTest test there are no issues. I guess that since my project structure is parent-with-two-children the need of /service is necessary(The project is created by pointing out the parent pom). Is there a way to fix this? Could you please help me with a solution. thx

  • Create Custom Builds of an Xcode Project

    - by macinjosh
    I am going to build a Mac application written in Obj-C with Xcode. For argument's sake let's say it will have 10 optional features. I need a way to enable or disable those features to create custom builds of the application. These builds would be automated (most likely through the Mac OS X Terminal) so I would need a way to state which of these features are enabled/disabled at build time (a configuration file or CLI arguments would be ideal.) So what is the best way to accomplish this? I'm trying to plan this out before I start coding so that there is proper separation in my code base to allow for these features to come and go. Ideally the custom build would only contain compiled code for the features it should have. In other words I don't want to always compile all the features and condition them out at runtime.

    - by gbacon
    I've been using PuTTYcyg as a Cygwin terminal, but it doesn't render dashes in manual pages correctly.

  • How to send a signal SIGINT from script to script ? BASH

    - by debugger
    I want to trap a signal send from Script-A.sh to Script-B.sh so in Script-A.sh i use the command (Send SIGINT to Script-B.sh) kill -2 $PID_Script-B.sh And in Script-B.sh i catch the signal and call function Clean trap 'Clean' 2 It does not work, instead the Script-B.sh is killed right away without performing the Clean !! What i notice also is that if i want to send SIGINT from terminal to any script that traps it, a ctrl-c will be catched correctly, but not if i specify the signal via the command kill -2 $pid_of_script Any idea about the difference between the two method to send the SIGINT (ctrl-c VS kill -2 $pid_of_script), and how i can send a SIGINT from a script to another ? Regards, Debugger

  • How to run infinitely script in background on Linux?

    - by Andrew Bashtannik
    I have a PHP script with infinite loop. I need this script running forever. So, I run php /path/to/script.php > /dev/null & And it works in background in my current user's security context. But when I close terminal window (log off), of course, CentOS Linux kills my program. I see two guesses: run from a different user in background or make a daemon. I need help in each situation. Thanks a lot!

  • Can I install WhizzyTeX for Emacs on a Mac (is Mac OS X a unix environment)?

    - by Vivi
    I think my question is pretty stupid, but here it goes: I am using Aquamacs, and I want to install the WhizzyTeX mode. The website for WhizzyTeX says that "it is designed for Unix platforms". I read that Mac OS X is unix certified, but does that mean I can install WhizzyTeX on my mac? If yes, can I install and use it with Aquamacs or do I have to use the Emacs running from the terminal? PS: I don't know whether this question should be posted here or on SuperUser, but as Emacs users seem to hang out here more often, this is the place I chose. EDIT: There are some websites saying I can use WhizzyTeX with Carbon Emacs on mac os x, but some places say I cannot (see for example this pdf document, page 27, which says that "* whizzytex: http://cristal.inria.fr/whizzytex/ mode in latex with ocaml good fo linux, should also work in cygwin, doe not work on osx"). So I am really confused...

  • Step-by-step execution for Intel AT&T assembler?

    - by Søren Haagerup
    Hello everyone, I'm writing a compiler that converts source code (written in a small imperative programming language) to Intel AT&T 32-bit assembler. I tend to spend a lot of time debugging, because of nasty offset-mistakes etc. in the generated code, and I would like to know if anyone knows of a tool to "walk through" the generated assembler code step-by-step, visualizing what's on the stack etc. I use Ubuntu Linux as my development platform, and I'm comfortable with the terminal -- a GUI-program would be nice though. Does it exist? Or is there a good reason it doesn't (maybe the problem isn't so straightforward..?) If you have good ideas for approaching debugging tasks in assembly code, I'll be glad to hear from you!

  • Compiling zip component for PHP 5.2.11 in MAMP PRO

    - by Zlatoroh
    Helo I installed MAMP PRO on my Macbook Pro (10.6) some time ago. Now I would like to use zip functions in php. I found that I must add zip.so to my extension folder and edited php.ini. On my computer I have two different versions of PHP one in MAMP folder and other in user/lib which was pre-installed on my system. Now I wish to compile my zip library for MAMP version. I got zip sources for my version of PHP then in terminal called function /Applications/MAMP/bin/php5/bin/phpize so it uses mamp php version ./configure make then I moved compile zip.so to extensions/no-debug-non-zts-20060613. When MAMP is launched it returns this error: [11-Apr-2010 16:33:27] PHP Warning: PHP Startup: zip: Unable to initialize module Module compiled with module API=20090626, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=0 These options need to match in Unknown on line 0 Can some body explain to me how to do this the right way.

  • How to define GPS module in Android?

    - by Osama Gamal
    I'm porting android to Devkit8000 which is a BeagleBoard clone. I have a GPS module connected on /dev/ttyS0. I could successfully get NMEA output when writing "cat /dev/ttyS0" in the terminal emulator. I want to know how to let android know that there is a GPS module on /dev/ttyS0 and it is outputting NMEA standard? To be able to use the android.location class with it! Is there something to edit in the android's source? adding driver for example, writing a code with android-ndk or what?

  • How can I install ruby on rails with rvm?

    - by yeahthatguyrightthere
    I've been searching around on how to install it through the terminal on my mac. I'm using snow leopard. When I use the command: rvm install 1.9.3 I've also followed the other procedures that led me up to this to install, right now the current version is 1.8.3 Error running './configure --prefix="/Users/jose/.rvm/usr" ', please read /Users/jose/.rvm/log/ruby-1.9.3-p125/yaml/configure.log Then it mentions something about xcode and autoreconf was not found in the PATH. Error running 'patch -F 25 -p1 -N -f <"/Users/jose/.rvm/patches/ruby/1.9.3/p125/xcode-debugopt-fix-e34840.diff"',please read /Users/jose/.rvm/log/ruby-1.9.3-p125/patch.apply.xcode-debugopt-fix-r34840.log rvm requires autoreconf to install the selected ruby interpreter however autoreconf was not found in the PATH I been trying for awhile now, and found out i need to have Xcode for snow leopard which I cannot find. So my last option will be to upgrade to lion but I don't know about upgrading. Kind of scared to upgrade and everything becomes buggy.

    hello all, i am using "use Win32::Process" for my application run as below, it runs fine but i did not get any way to get the output to a .txt file. i used NORMAL_PRIORITY_CLASS rather than CREATE_NEW_CONSOLE to get the output on the same terminal itself but i don't know how to redirect it to a txt file. /rocky !/usr/bin/perl use strict; use warnings; use Win32::Process; Win32::Process::Create(my $ProcessObj, "iperf.exe", "iperf.exe -u -s -p 5001", 0, NORMAL_PRIORITY_CLASS, ".") || die ErrorReport(); my @command_output; push @command_output,$ProcessObj; open FILE, "zz.txt" or die $!; print FILE @command_output; close FILE; sleep 10; $ProcessObj-Kill(0); sub ErrorReport{ print Win32::FormatMessage( Win32::GetLastError() ); }

  • Negative execution time

    - by FinalArt2005
    Hello, I wrote a little program that solves 49151 sudoku's within an hour for an assignment, but we had to time it. I thought I'd just let it run and then check the execution time, but it says -1536.087 s. I'm guessing it has to do with the timer being some signed dataype or something, but I have no idea what datatype is used for the timer in the console (code::blocks console, I'm not sure if this is actually a separate console, or just a runner that runs the terminal from the local operating system), so I can't check what the real time was. I'd rather not run this again with some coded timer within my program, since I'd like to be able to use my pc again now. Anybody have any idea what this time could be? It should be somewhere between 40 and 50 minutes, so between 2400 and 3000 seconds. Regards, Erik

  • Installing ant; clearly misunderstanding JAVA_HOME

    - by StormShadow
    Hey all, I am installing ant on a Windows XP machine, and am following the instructions at Apache's manual site. It said to set JAVA_HOME, so I checked, saw there was no environment variable named JAVA_HOME, made one, and set it to "C:\Program Files\Java\jdk1.6.0_19" When I try to run ant debug, however, it tells me that JAVA_HOME is currently set to "C:\Program Files\Java\jre6" I'm guessing JAVA_HOME isn't an environment variable. But if it isn't one, I'm at a loss as to where to start looking for it. Anybody know? Edit: Oh yeah - it's bugging me for tools.jar as well, but I'm guessing that when I fix the JAVA_HOME issue, that will help the terminal find tools.jar as well. Or maybe I'm wrong. Thanks

  • Gigantic Tabs in Eclipse on Ubuntu

    - by Zack
    Short version: How do I make a short version of Eclipse's tabs & toolbars in Ubuntu? I've been looking around for a fix to this on Google, but to no avail. With any GTK theme, I still have this same issue and it's very, very annoying--to the point where I've stopped using Eclipse in favor of gEdit. However, after running pylint from a terminal too. many. times. I've decided I need to find a solution to this issues with Eclipse so I can have PyDev back. Here's what the tabs look like: As you can see, not only are the tabs exaggerated, but the toolbar is, too: so is the toolbar on the bottom; so are the tabs in the bottom pane. Overall, it's eating up a lot of screen space, which is a hard item to come by on a 17" screen. Any suggestions/fixes?
