之前寫過一版 shell下解碼url，下面給出另外一個版本

from https://gist.github.com/cdown/1163649

function urlencode() {    local LANG=C    for ((i=0;i<${#1};i++)); do        if [[ ${1:$i:1} =~ ^[a-zA-Z0-9\.\~\_\-]$ ]]; then            printf "${1:$i:1}"        else            printf ‘%%%02X‘ "‘${1:$i:1}"        fi    done}urldecode() {    # urldecode <string>    local url_encoded="${1//+/ }"    printf ‘%b‘ "${url_encoded//%/\\x}"}

好用就行
