urlencode for shell

urlencode.sh

function urlencode() {
    local data
    if [[ $# != 1 ]]; then
        echo "Usage: $0 string-to-urlencode"
        return 1
    fi
    data="$(curl -s -o /dev/null -w %{url_effective} --get --data-urlencode "$1" "")"
    if [[ $? == 0 ]]; then
        echo "${data##/?}"
    fi
    return 0
}

do NOT use the above snippet, it's not reliable.

echo $1 | perl -MURI::Escape -lne 'print uri_escape($_)'

just use
curl --data-urlencode 'key=val' URL
is OK. do not use other useless scripts.

A bash script that works based on the one in this gist:

#!/bin/sh

set -eu

# SAVE THIS FILE AND GIVE IT EXECUTABLE PERMISSIONS
# Then execute it like this: ./urlencode.sh https://apibaas.io
# Output: https%3A%2F%2Fapibaas.io

Main() {

  local input=${1? Missing the data to URL encode...}

  local data="$(curl -s -o /dev/null -w %{url_effective} --get --data-urlencode "${input}" "")"

  echo "${data##/?}"
}


Main "${@}"
