Url_encode and Url_decode in Shell

Previously wrote a version of the shell decoding URL, the following gives another version

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}"        Elseprintf'%%%02x' "' ${1: $i: 1}"fi Done}urldecode () {# UrlDecode<string>Local url_encoded="${1//+/}"printf'%b' "${url_encoded//%/\\x}"}

It works.
