Just add the escape sequences in iTerm settings as global shortcut keys.

Word backward (option-arrowleft):

![a iTerm settings](http://i.imgur.com/2akWjSO.png)

Same with word forward, just use `F`.


The easiest/quickest way I have found is under Profiles &gt; Keys &gt; &#39;Load Preset...&#39; &gt; &#39;Natural Text Editing&#39;.

Then use the `option` key rather than the `control` key.

(iterm2 version 3)

Killing a fly with a cannon:

 - Go to **Preferences...** &gt; **Profiles** &gt; **Keys**
 - Press **Load Preset...**
 - Select **Natural Text Editing**

Then, you can move a word backwards using &lt;kbd&gt;Option ⌥&lt;/kbd&gt; + &lt;kbd&gt;←&lt;/kbd&gt; and a word forwards using &lt;kbd&gt;Option ⌥&lt;/kbd&gt; + &lt;kbd&gt;→&lt;/kbd&gt;, move to the start of the line using &lt;kbd&gt;fn&lt;/kbd&gt; + &lt;kbd&gt;←&lt;/kbd&gt; and to the end of the line with &lt;kbd&gt;fn&lt;/kbd&gt; + &lt;kbd&gt;→&lt;/kbd&gt;. Also you can delete a word backwards using &lt;kbd&gt;Option ⌥&lt;/kbd&gt; + &lt;kbd&gt;⌫&lt;/kbd&gt;, delete the whole line using &lt;kbd&gt;Command ⌘&lt;/kbd&gt; + &lt;kbd&gt;⌫&lt;/kbd&gt;.

If the preset doesn&#39;t appear, reinstall iTerm2. If you installed it using Homebrew+Cask:

    brew cask reinstall iterm2

mission control took over the same commands as word jumping. thanks to rob cowrie and nicholas riley for the heads-up on that.

I added the following in my /etc/inputrc

    # word jump on SHIFT left/right arrows
    &quot;\e[1;2D&quot;: backward-word
    &quot;\e[1;2C&quot;: forward-word

it works great

Following the steps listed in the above answers, I found that on my laptop the first bash (1.bash) will not be able to jump words by pressing option + arrow. Instead, it will simply type in &quot;[D&quot;,&quot;[C&quot;. However, if I create a new bash window (2. bash), the word jump works.

I&#39;m currently building a program which adds to the current user&#39;s shell depending on the project he&#39;s working on, by defining per-project aliases and functions. These aliases and functions may and will certainly have the same name like for instance `cdproj`, which would `cd` to the project&#39;s root.

I would like to remove previously defined aliases and functions when changing project (before (re)defining aliases and functions for the other project. I know I can remove an alias with `unalias` in both bash and zsh, but how would I do the same for a function?

Remove function definition (unalias equivalent)

The Task Parallel Library is great and I&#39;ve used it a lot in the past months. However, there&#39;s something really bothering me: the fact that [`TaskScheduler.Current`][1] is the default task scheduler, not [`TaskScheduler.Default`][2]. This is absolutely not obvious at first glance in the documentation nor samples.

`Current` can lead to subtle bugs since its behavior is changing depending on whether you&#39;re inside another task. Which can&#39;t be determined easily.

Suppose I am writting a library of asynchronous methods, using the standard async pattern based on events to signal completion on the original synchronisation context, in the exact same way XxxAsync methods do in the .NET Framework (eg `DownloadFileAsync`). I decide to use the Task Parallel Library for implementation because it&#39;s really easy to implement this behavior with the following code:

    public class MyLibrary
    {
        public event EventHandler SomeOperationCompleted;

        private void OnSomeOperationCompleted()
        {
            SomeOperationCompleted?.Invoke(this, EventArgs.Empty);
        }

        public void DoSomeOperationAsync()
        {
            Task.Factory.StartNew(() =&gt;
            {
                Thread.Sleep(1000); // simulate a long operation
            }, CancellationToken.None, TaskCreationOptions.None, TaskScheduler.Default)
            .ContinueWith(t =&gt;
            {
                OnSomeOperationCompleted(); // trigger the event
            }, TaskScheduler.FromCurrentSynchronizationContext());
        }
    }

So far, everything works well. Now, let&#39;s make a call to this library on a button click in a WPF or WinForms application:

    private void Button_OnClick(object sender, EventArgs args)
    {
    	var myLibrary = new MyLibrary();
    	myLibrary.SomeOperationCompleted += (s, e) =&gt; DoSomethingElse();
    	myLibrary.DoSomeOperationAsync(); // call that triggers the event asynchronously
    }

    private void DoSomethingElse() // the event handler
    {
        //...
    	Task.Factory.StartNew(() =&gt; Thread.Sleep(5000)); // simulate a long operation
        //...
    }

Here, the person writing the library call chose to start a new `Task` when the operation completes. Nothing unusual. He or she follows examples found everywhere on the web and simply use `Task.Factory.StartNew` without specifying the `TaskScheduler` (and there is no easy overload to specify it at the second parameter). The `DoSomethingElse` method works fine when called alone, but as soon at it&#39;s invoked by the event, the UI freezes since `TaskFactory.Current` will reuse the synchronization context task scheduler from my library continuation.

Finding out this could take some time, especially if the second task call is buried down in some complex call stack. Of course, the fix here is simple once you know how everything works: always specify `TaskScheduler.Default` for any operation you&#39;re expecting to be running on the thread pool. However, maybe the second task is started by another external library, not knowing about this behavior and naively using `StartNew` without a specific scheduler. I&#39;m expecting this case to be quite common.

After wrapping my head around it, I can&#39;t understand the choice of the team writing the TPL to use `TaskScheduler.Current` instead of `TaskScheduler.Default` as the default:

 - It&#39;s not obvious at all, `Default` is not the default! And the documentation is seriously lacking.
 - The real task scheduler used by `Current` depends of the call stack! It&#39;s hard to maintain invariants with this behavior.
 - It&#39;s cumbersome to specify the task scheduler with `StartNew` since you have to specify the task creation options and cancellation token first, leading to long, less readable lines. This can be alleviated by writing an extension method or creating a `TaskFactory` that uses `Default`.
 - Capturing the call stack has additional performance costs.
 - When I really want a task to be dependent on another parent running task, I prefer to specify it explicitly to ease code reading rather than rely on call stack magic.

I know this question may sound quite subjective, but I can&#39;t find a good objective argument as to why this behavior is as it. I&#39;m sure I&#39;m missing something here: that&#39;s why I&#39;m turning to you.

I recently upgraded from Snow Leopard to Lion and Xcode 4.1, and word jumping stopped working in both Terminal and iTerm2. Did the mappings change?

This is with *and* without a homebrew installation of `readline`.

My `.inputrc` looks like this:

    &quot;\e[1;5D&quot;: backward-word
    &quot;\e[1;5C&quot;: forward-word

Thanks!

Word jumping in iTerm2 or Terminal in OSX Lion

I recently upgraded from Snow Leopard to Lion and Xcode 4.1, and word jumping stopped working in both Terminal and iTerm2. Did the mappings change?
This is with and without a homebrew installation of <code>readline</code>.
My <code>.inputrc</code> looks like this:
<pre><code class="hljs language-arduino">"\e[1;5D": backward-word
"\e[1;5C": forward-word
</code></pre>
Thanks!

I have done all kinds of research and tried many different things. I know this question has been answered many times, but none of the suggested solutions are working for me.

After upgrading to Lion I am getting segmentation faults in Ruby. I&#39;m fairly confident it&#39;s Nokogiri. So I installed libxml2 via Homebrew. I ran `brew link libxml2`. Then I reinstalled Nokogiri using that version of the library.

For proof:

    $ nokogiri -v
    # Nokogiri (1.5.0)
    ---
    warnings: []
    nokogiri: 1.5.0

      engine: ruby
    libxml:
      binding: extension
      compiled: 2.7.8
      loaded: 2.7.8

I&#39;ve already included Nokogiri at the top of my gemfile and I&#39;ve also required it in my environment file. I have no idea why I am still getting that warning.

Any suggestions or ideas to make sure it&#39;s loading the right version libxml2?

I&#39;m a little confused with the python on osx. I do not know if the previous owner of the laptop has installed macpython using macport. And I remembered that osx has an builtin version of python. I tried using `type -a python` and the result returned 

    python is /usr/bin/python
    python is /usr/local/bin/python

However running both python at these locations give me `[GCC 4.2.1 (Apple Inc. build 5646)] on darwin`. Do they both refer to the same builtin python mac provided?

I also read that installing macpython one would 

         A MacPython 2.5 folder in your Applications folder. In here you
     find IDLE, the development environment that is a standard part of
     official Python distributions...

I looked at `Applications`, and theres a `MacPort` folder with `python2.6` and the mentioned stuff in it. But running IDLE, i find the same message as above.

Hmm I&#39;m a little confused. Which is which?

I&#39;ve searched a bit, but I can&#39;t find an existing tool for this.

I have a Node.js web server that is designed to run on your own computer that does some snazzy things for you.  It would be pretty awesome if I could double click `MySnazzyThing.app` instead of installing Node.js, and npm and running `node mysnazzyapp.js` on the command line.

The `.app` executable would spool up the Node.js server and open a simple native [WebKit][1] window which would show what would normally be on `localhost:3000` if I were running on the command line.

This native application could then, say, be distributed through the Mac [App&amp;nbsp;Store][2].  And bam, a Node.js desktop application.

Does any such tool exist? Or are there any technical reasons that this wouldn&#39;t work as I imagine it?

After upgrading to Mac OSX Lion I figured out that /etc/hosts is not looked up in first place for name resolution anymore. This leads to some side effects like:

 1. Entries in /etc/hosts are resolved painfully slow
 2. You can&#39;t not override existing domains, e.g. 127.0.0.1 www.google.com
 3. If you get search domain entries from DHCP, let say .lan, and some funny guy configured localhost.lan to something else then 127.0.0.1 in the local DNS you can not reach your localhost anymore.

Is this behavior intended? Does it make any sense? And most important, how can I come back to the old behavior.

After the installation of OSX Lion, I tried to:

    nano /etc/apt/sources.list

But I get this error:

    Error opening terminal: xterm-256color

If I try to switch terminal.app preferences to open terminal windows in &quot;xterm color&quot; instead of `xterm-256color` everything works fine.

What&#39;s happening?

I want to differentiate the STDOUT and STDERR messages in my terminal.
If a script or command is printing a message in terminal I want to differentiate by colors; is it possible?

(E.g. stderr font color is red, and stdout font color is blue.)

Example (using bold):

&gt; `$date`  
&gt; `Wed Jul 27 12:36:50 IST 2011`
&gt;
&gt; `$datee`  
&gt; **`bash: datee: command not found`**
&gt;
&gt; `$alias ls`  
&gt; `alias ls=&#39;ls --color=auto -F&#39;`
&gt;
&gt; `$aliass ls`  
&gt; **`bash: aliass: command not found`**

I want to mask my password while writing it with `*`.
I use Linux GCC for this code.
I know one solution is to use `getch()` function like this

    #include &lt;conio.h&gt;   
    int main()
    {
        char c,password[10];
        int i;
        while( (c=getch())!= &#39;\n&#39;);{
            password[i] = c;
            printf(&quot;*&quot;);
            i++;
        }
        return 1;
    }

but the problem is that `GCC` does not include `conio.h` file so, `getch()` is useless for me.
Does anyone have a solution?

I primarily use Visual Studio and ReSharper (R#) for development and have excellent working knowledge of R#. I want to leverage that knowledge in IntelliJ IDEA (with my personal Java adventures) without having to learn the IDEA keymap scheme. IDEA has a Visual Studio keymap but that mainly updates such key bindings as Find (Ctrl + F) and Replace (Ctrl + H) etc. Because Visual Studio doesn&#39;t have built-in capabilities like &quot;Inspect This...&quot; etc. (the kinda stuff provided by R#), those IntelliJ keybinding in Visual Studio keymap are merely a dump of IDEA&#39;s.

In VS.NET, ReSharper comes with two keymaps, IDEA and Visual Studio. I&#39;ve been using the Visual Studio keymap since R# 5 and really would like to have a keymap in IntelliJ idea that actually is a combination of the Visual Studio IDEA keymap and R# Visual Studio keymap. This combinational keymap is what I am calling Visual Studio ReSharper (R#) keymap for IntelliJ IDEA.

I&#39;d appreciate if someone can share thier keymap if they have created one that&#39;s close to the stated description. If JetBrains is hearing, how about bundling an additional keymap scheme with IntelliJ that&#39;s essentially a combination of Visual Studio scheme (in IntelliJ IDEA) and ReSharper Visual Studio scheme (in VS.NET)?

In Vim, when I hit the `backspace` key in the `insert` mode, it leaves `^?` character and does not delete the character it is suppose to delete. 

I have the following in my `.vimrc`

    syntax on
    set number
    set expandtab
    set incsearch
    set nocompatible
    set backspace=indent,eol,start
    fixdel

This happens in the command mode too. When I wrongly type `W` instead of `w` to save, I press `backspace` key and it gives me the following:

    :W^?

Any idea on whats wrong and how to fix it?!
