Compiling packages from source on Ubuntu

A default Ubuntu install doesn't come with many compiling tools like GCC, G++, libc6-dev, and Make that you need to compile programs from source. To get all those packages, type in:

sudo apt-get install build-essential

You will need the Ubuntu CD for this.

Jump words with Control-Arrow in the Ubuntu terminal

On a fresh install of both Ubuntu 7.04 and 7.10, pressing Ctrl-[Arrow Key] does not jump words but instead writes a control code onto the screen such as ;5C or ;5D.

To fix this, add export INPUTRC=/etc/inputrc to /etc/bash.bashrc.

Make sure /etc/inputrc has these lines in it:

# mappings for Ctrl-left-arrow and Ctrl-right-arrow for word moving
"\e[1;5C": forward-word
"\e[1;5D": backward-word
"\e[5C": forward-word
"\e[5D": backward-word
"\e\e[C": forward-word
"\e\e[D": backward-word
