Migrar .sh a otro lenguaje <- HELP

[culd]

Buenas, tengo un .sh de linux, y lo quisiera mirar a otro lenguaje para poder crear un .exe

La verdad que no intiendo un poco de secuencial shell en linux, lo que necesito es poder subir archivos a megaupload.

Código:

#!/bin/bash
#
# Upload a file to megaupload (anonymously or using a registered account).
# Output URL for the uploaded file.
#
# Dependencies: curl
#
# Web: http://code.google.com/p/megaupload-dl
# Contact: Arnau Sanchez <[email protected]>.

AGENT="Mozilla Firefox / 3.01"

# Echo text to standard error.
#
debug() { echo "$@" >&2; }

curl() {
  while true; do
      $(type -P curl) "$@" && DRETVAL=0 || DRETVAL=$?
      if [ $DRETVAL -eq 6 -o $DRETVAL -eq 7 ]; then
          debug "curl failed with retcode $DRETVAL, trying again"
          continue
      else
          return $DRETVAL
      fi
  done
}

# Get first line that matches a regular expression and extract string from it.
#
# $1: POSIX-regexp to filter (get only the first matching line).
# $2: POSIX-regexp to match (use parentheses) on the matched line.
#
parse() { sed -n "/$1/ s/^.*$2.*$/\1/p" | head -n1; }

# Login to megaupload and return cookies
#
# $1/$2: User/password
login() {
    USER=$1
