Montador de imágenes ISO
Nombre: mntiso
Autor: Luis Moreno Rodriguez
Lenguaje: Bash
Licencia: GPL
Monta de forma automática imágenes ISO usando los dispositivos /dev/loop. Es capaz de montar varias imágenes a la vez ya que busca cuales son los dispositivos loop que no están siendo usados. También puede montar una misma imagen varias veces usando automáticamente distintas carpetas de montaje.
El script siempre mostrará donde se monta cada imagen; por defecto las imágenes son montadas de forma independiente en la carpeta "mounted_ISO" en el directorio home del usuario. Este aspecto se puede configurar fácilmente editando una variable en el script.
Soporta paths relativos y absolutos.
