Update bash on OS X using homebrew

Default bash on MAC OS X sucks, that's why we have to get a better one. The easiest way is using homebrew.

First step is to install homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

then install bash

brew install bash

after that, you can go to see if new bash is install correctly

ls -al /usr/local/bin | grep bash

The result should show the symlink (->) like this

lrwxr-xr-x   (some useless info here)  bash -> ../Cellar/bash/4.3.18/bin/bash

The version might not be exactly 4.3.18, but everything above that is okay.


Now it's time to update your bash by create symlink to /usr/bin/bash.
But, before we can create symlink, just in case something go wrong, we have to backup the existing bash first.

sudo mv -r /usr/bin/bash /usr/bin/bash_old

then crete symlink from /usr/local/bin/bash to /usr/bin/bash

sudo ln -s /usr/local/bin/bash /usr/bin/bash 

After you restart terminal, everything should be ready

If you're still not convince, you can try

bash --version 

how to set different wallpaper for each monitor in Ubuntu

Update: Nitrogen doesn't work well on Ubuntu 13.04

Setting different wallpaper for each screen is really more difficult than on Windows or OS X but isn't that difficult

There are just 2 steps.

First install GNOME Tweak Tool using command line.

sudo apt-get install gnome-tweak-tool

Now we have to stop file manager from handle the desktop background.

The desktop is now gone black, so we can use another application to handle it



Second, install nitrogen.

sudo apt-get install nitrogen

But nitrogen doesn't have icon so we have to launch it from a command line by typing

nitrogen

Now we can set different wallpaper for each screen.
