vim settings / tricks i use

Here are some settings i personally use.
I will extend this post as soon as discover more.

/etc/vimrc

syntax on (syntax highlighting)
set number (line numbers)
set keywordprg=perldoc\ -f (shift-k opens perldoc for item under cursor )

Extended bash tab completion

Just install the package "bash-completion" in archlinux und you will get extended tab completion for the following programs: http://wklej.org/id/808581

*edit: Make sure  "/etc/bash.bashrc" is up-to-date otherwise it may not work.

Even tab completion for rsync and scp remote files structures works now.

Bash prompt shortener

Add this to your ~/.bashrc

# Bash shortener
_PS1 ()
{
    local PRE= NAME="$1" LENGTH="$2";
    [[ "$NAME" != "${NAME#$HOME/}" || -z "${NAME#$HOME}" ]] &&
        PRE+='~' NAME="${NAME#$HOME}" LENGTH=$[LENGTH-1];
    ((${#NAME}>$LENGTH)) && NAME="/...${NAME:$[${#NAME}-LENGTH+4]}";
    echo "$PRE$NAME"
}

PS1=' \[\e[0m\]\u\[\e[0;32m\]@\[\e[0m\]\h \[\e[0;32m\]$(_PS1 "$PWD" 30) \[\e[0m\]$ '

It will shorten the path in your bash prompt to 30 chars.

Start applications with the default app from console

Its as simple as. Add this to your ~/.bashrc

alias open='nohup xdg-open >/dev/null 2>&1'

 Now you can start, for example a textfile, like this "open textfile.txt". Because of nohop in the alias you can even close the console session and the text editor stays open.
