Variables anidadas: El contenido del contenido de una variable en bash

Casi me vuelvo loco, pero en fin, este script nos podrá indicar como conseguir tal cosa (sobran unas cuantas lineas, que he estado utilizando hasta que he dado con la solución):

sl01="/var/www";
var=$sl01;
echo $var;
servidor="sl01";
echo servidor = $servidor;
echo $`echo $servidor`;
dato=$`echo $servidor`;
echo dato = $dato;
comando='echo '`echo $dato`;
echo "comando= $comando";
echo `test dato`;
$comando;

valor=`eval echo '$'${servidor}`;
echo el contenido de la variable $servidor es $valor;

montar un ftp dentro de tu sistema de archivos

Lo transcribo tal cual lo encontré en la web “http://blog.mypapit.net/2007/05/how-to-use-ftp-filesystem-on-ubuntu-using-curlftpfs.html”. Cuando tenga tiempo ya lo traduciré.

Some web hosting company do not offer shell access (SSH or Telnet) to your shared hosting account for security reasons, making it a bit harder for you to do regular file maintenance for your web account. Although the use of regular FTP client is adequate for most cases, some people still prefer to manipulate files directly using standard Unix tools (probably because of old habits).

Fortunately, there’s CurlFtpFS which allow you to mount remote ftp account as a standard filesystem on your Linux operating system.

Using CurlFtpFS
First of all you need to install CurlFtpFS, which in case of Ubuntu or Debian based operating system is to run ’sudo apt-get install curlftpfs’.

Alternatively, you can use Synaptic to install CurlFtpFS.

Assuming you’ve successfully installed curlftpfs, all you need to do in order to mount ftp locally is to to run these commands.

mkdir hostr

sudo curlftpfs -o allow_other ftp://user:pass@ftp.example.com hostr

user:pass is the username and password to log into ftp account.

After that, you can change your working directory to the mount-point and use the regular unix utilities to work on the files that normally accessible on the FTP protocol. After you’re done, you can unmount it by running the usual “sudo umount [mountpoint]” command

Using CurlFtpFS in fstab
You can add curlftpfs to fstab for automatic mounting by using this line :

curlftpfs#user:pass@ftp.example.com /mnt/host fuse rw,uid=500,user,noauto 0 0

Note: Please refer to CurlFtpFS website for further reference.

Thanks for reading this post, hopefully this will get you started to use curlftpfs FTP based filesystem in your Linux operating system.

Instalar programas de windows en GNU-Linux / instalar programas de GNU-Linux en windows

Para instalar programas de windows en tu GNU/Linux tienes estas opciones (libres):

- instalar wine (desde apt-get) y luego ejecutar winecfg (para configurar wine). Esto te generará las librerías necesarias para poder instalar y ejecutar programas para windows.

- Usar wine-doors (Que es un sistema que permite instalar ciertos programas de windows de una forma parecida a Synaptic) http://wddb.wine-doors.org/

- PlayOnLinux (Otro sistema parecido) http://www.playonlinux.com/es/

Para instalar programas de GNU/Linux en tu windows:

Te recomiendo que entonces formatees tu windows y te instales una distribución de GNU/Linux, pero si no quieres hacer esto, puedes navegar a http://portableubuntu.demonccc.cloudius.com.ar/ y descargarte portable ubuntu.

Esto te generará una instalación de un sistema linux básico con gnome integrado en tu escritorio de windows.

Off topic: Hotels&Blogs

Andreu Llabrés ha tenido una idea fantástica.

Se le ha ocurrido la idea de ofrecer una noche gratis de hotel a todo blogger que esté dispuesto a publicar luego acerca de su experiencia en el hotel.

Creo que es un estupéndo mecanismo publicitario para los hoteles.

Requisitos:

• Disponer de un blog
• Escribir un comentario sobre Hotels&Blogs en tu blog
• Dejarle un comentario con las ciudades donde le gustaría pasar la noche de hotel gratis.

Lo vais a intentar? yo por supueto SI (solo espero que en mi noche de hotel, haya wifi disponible)
