Tips & Tricks

History Search

Usually, pressing the <up> key will cause the last command to be shown, no matter what you typed so far. However, many users find it more practical to only past commands that begin with the current input.

Consider this list of commands:
ls /usr/src/linux-2.6.15-ARCH/kernel/power/Kconfig
who
mount
man mount

Usually, when typing 'ls' and pressing <up>, your current input will be replaced with man mount. If you are using history seach, only past commands beginning with 'ls' (the current input) will be shown, in this case 'ls /usr/src/linux-2.6.15-ARCH/kernel/power/Kconfig'.

You can enable this mode by adding to /etc/inputrc or your ~/.inputrc

"\e[A":history-search-backward
"\e[B":history-search-forward

Enabling Bash Completion

Enabling bash completion is quite simple. Here's how.

pacman -Sy bash-completion

Edit ~/.bashrc and add the following:

# enable bash completion in interactive shells
if [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
fi
