From within a terminal, try

    sudo update-alternatives --config x-terminal-emulator

Select the desired terminal from the list of alternatives.

change Settings Manager &gt;&gt; Preferred Applications &gt;&gt; Utilities

Copy-paste the following into your current terminal:

    gsettings set org.gnome.desktop.default-applications.terminal exec /usr/bin/terminator
    gsettings set org.gnome.desktop.default-applications.terminal exec-arg &quot;-x&quot;

This modifies the [dconf][1] to make terminator the default program. You could also use dconf-editor (a GUI-based tool) to make changes to the dconf, as another answer has suggested. If you would like to learn and understand more about this topic, [this][2] may help you.

[devnull][1] is right; 

    sudo update-alternatives --config x-terminal-emulator

works. See [here][2] and [here][3], and some comments in [here][4].

In xfce (e.g. on Arch Linux) you can change the parameter `TerminalEmulator`:

     TerminalEmulator=xfce4-terminal

to 

    TerminalEmulator=custom-TerminalEmulator


The next time you want to open a terminal window, xfce will ask you to choose an emulator. You can just pick `/usr/bin/terminator`.

# System Defaults

    /etc/xdg/xfce4/helpers.rc

# User Defaults

    /home/USER/.config/xfce4

The only way that worked for me was

1. Open nautilus or nemo as root user `gksudo nautilus`
2. Go to /usr/bin
3. Change name of your default terminal to any other name for exemple &quot;orig_gnome-terminal&quot;
4. rename your favorite terminal as &quot;gnome-terminal&quot;

Everyone is aware of `this` in javascript, but there are also instances of `self` encountered in the wild, such as [here](https://github.com/LeaVerou/conic-gradient/blob/11f946cae718e50a8321c168dc9336da97bd1622/conic-gradient.js#L17)

So, what is the difference between `this` and `self` in JavaScript?

I&#39;d like to have [Terminator](https://gnome-terminator.org/) replace the default terminal. For instance, when right-clicking inside a folder then selecting &quot;open terminal&quot;, I&#39;d like Terminator to open instead of the default.

How can I achieve this using Xubuntu?

I would like to install NodeJS version 0.8.18 on Ubuntu 12.04. I tried to install the newest version and then reverting to 0.8.18 by using `nvm`, but when I run my code apparently there is some problem with the packages installed and the two versions (latest and 0.8.18). Since I don&#39;t know how to solve that problem, I cleaned the machine from the Node installation and thought about installing directly the version I&#39;m interested in (v0.8.18).

How can I setup `JAVA_HOME` path without having to set it each time I restart my machine?

I&#39;ve used the following ways when trying to set JAVA_HOME on my Ubuntu machine:

1) From terminal I&#39;ve executed the following command:

    export JAVA_HOME=/usr/lib/jvm/jdk1.7.0

2) I&#39;ve edited the `/etc/enviroment` file directly to add `JAVA_HOME` path in it

What&#39;s really strange is that if I test `JAVA_HOME` using the `echo` command after an of the above two ways, I can see it is set correctly, but if I restart, logout/ login again or even after working on the machine for a while the `JAVA_HOME` is no more set and I have to set it again using any of the above two ways.

So can someone please tell me what I am doing wrong here?

I am trying to install NVM as per these [instructions][1] 

I typed in this command in terminal:

    $ curl https://raw.github.com/creationix/nvm/master/install.sh | sh

After running the install, I restart the terminal and attempt to install Node.js with this command:

    $ nvm install 0.8

but I get the response:

    -bash: nvm: command not found

I&#39;m not sure what I am doing wrong here.

Additional Info--

I&#39;ve been looking around for solutions from other posts and forums. I found another solution using

    $ git clone git://github.com/creationix/nvm.git ~/.nvm

but this times out every time I attempt that. Any help would be appreciated. Thanks.

Node Version Manager install - nvm command not found

By default `git diff` prints all `+-` lines to the stdout however I have a (devian) machine (which I connect through ssh) where `git diff` leads me to an editor (which I don&#39;t know which is) and I need to press &lt;kbd&gt;q&lt;/kbd&gt; to continue.

I&#39;ve checker git config and it looks like :

    $ git config --list
    user.name=XXX
    user.email=XXX@XXX
    color.ui=false
    difftool.prompt=false
    mergetool.prompt=false
    core.repositoryformatversion=0
    core.filemode=true
    core.bare=false
    core.logallrefupdates=true
    remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
    remote.origin.url=XXX
    branch.master.remote=origin
    branch.master.merge=refs/heads/master
    $ git config --global --list
    user.name=XXX
    user.email=XXX@XXX
    color.ui=false
    difftool.prompt=false
    mergetool.prompt=false
    $ git config --system --list
    &#39;/etc/gitconfig&#39;: No such file or directory

Is there a place I am missing? Maybe the unknown tool is a fallback or something because I my machine is missing something? Any help is appreciated. Thanks.



How to make git diff write to stdout?

I&#39;ve been watching some of the Team Treehouse videos and they have a very nice looking terminal when working with Git.

For example they have (something similar):

    mike@treehouseMac: [/Work/test - feature-branch-name] $ git add .
    mike@treehouseMac: [/Work/test - feature-branch-name] $ git commit -m &quot;Some feature.&quot;
    mike@treehouseMac: [/Work/test - feature-branch-name] $ git checkout master
    mike@treehouseMac: [/Work/test - master] $ git status

How can my terminal show me some useful information of what branch I&#39;m on, with colors to distinguish bits of the data I want? Is there some sort of de-facto plugin I haven&#39;t found yet?

I&#39;m using Mac OSX 10.8

How can I display the current branch and folder path in terminal?

I don&#39;t like CMD.EXE, the built-in Windows terminal. Among its problems:

1. Hard to copy and paste.

2. Hard to resize the window.

3. Hard to open another window (no menu options do this).

4. Seems to always start in C:\Windows\System32, which is super useless.

5. Weird scrolling. Sometimes it scrolls down really far into blank space, and you have to scroll up to where the window is actually populated.

I love Cygwin, but the problem with Cygwin is that it runs different executables. The Cygwin Python is different than the Windows Python, they are linked against different libraries and stuff.

Thanks.

Alternative Windows shells, besides CMD.EXE?

This is what I used to do in tmux to copy-paste (using the mouse, the keyboard works differently and it is not what I am interested about):

 1. Select text with mouse, left-button pressed
 2. Paste text with middle-button

I have upgraded my OS, and this has gotten a new tmux version. I have not changed my `.tmux.conf` config file.

This is what I have to do with the current version of `tmux`, `1.6` (which comes pre-packaged in the latest crunchbang linux):

 1. Select text with mouse, left-button pressed **and** &lt;kbd&gt;shift&lt;/kbd&gt; key
 2. Paste text with middle-button
 3. Terminal gets blocked, a litte information area shows some numbers on the top right of the current pane (i.e. `[0/24]`, probably something related to how many characters have been pasted), which mean little to me and I do not need / want (edit: it seems `copy-mode` is entered automatically here)
 4. I have to press the &lt;kbd&gt;q&lt;/kbd&gt; key to get a functional terminal again.

This is too much hassle for something I do dozens of times a day. How to get the old mechanism working again?
