搞来个的解压缩函数，哈哈，够懒的

dotfiles.org 搞来的解压缩，哈哈

###   Handy Extract Program

extract () {
    if [ -f $1 ] ; then
        case $1 in
            *.tar.bz2)   tar xvjf $1   ;;
            *.tar.gz)    tar xvzf $1   ;;
            *.bz2)       bunzip2 $1    ;;
            *.rar)       unrar x $1    ;;
            *.gz)        gunzip $1     ;;
            *.tar)       tar xvf $1    ;;
            *.tbz2)      tar xvjf $1   ;;
            *.tgz)       tar xvzf $1   ;;
            *.zip)       unzip $1      ;;
            *.Z)         uncompress $1 ;;
            *.7z)        7z x $1       ;;
            *)           echo "'$1' cannot be extracted via >extract<" ;;
        esac
    else
        echo "'$1' is not a valid file"
    fi
}

BBC 的天气预报，似乎不太准哦

此为上海三天内的天气Feed

wget -q -O - http://newsrss.bbc.co.uk/weather/forecast/1713/Next3DaysRSS.xml | grep title | sed -e "s/<[^>]*>//g" -e "s/°//g" | egrep "^[A-Z]"

此外，BBC Weather也有提供iFrame嵌入：

List dir tree in bash

This is a simple "tree" command:

find . -type d | sed -e "s/[^-][^\/]*\//  |/g" -e "s/|\([^ ]\)/|-\1/"

Alias it and have fun!!
