create 4 scripts. The first script call congelar.sh and write this: #!/bin/sh cd / cd /home/administrador/Escritorio sudo -S cp -rfp congela /etc/init.d sudo -S cp -rfp num-up /etc/init.d cd / cd /etc/init.d sudo -S chown root:root congela sudo -S chmod 755 congela sudo -S chown root:root num-up sudo -S chmod 755 num-up cd / cd /etc/rc2.d sudo -S ln -s /etc/init.d/congela ./S20congela sudo -S ln -s /etc/init.d/num-up ./S20num-up cd / cd tmp mkdir congelado cd / cd /home/administrador sudo -S tar -cpPf /home/administrador/backup-congelado.tar /home/congelado Then congela.sh: rm -rf /tmp/congelado mkdir /tmp/congelado mv /home/congelado /tmp/congelado tar -xpPf /home/administrador/backup-congelado.tar /home/congelado echo "Modulo de resguardo cargado..." then recongelado.sh #!/bin/sh cd / cd /home/laboratorio sudo -S umount Documentos cd / cd /home/administrador sudo -S rm -rf backup-laboratorio.tar sudo -S tar -cpPf /home/administrador/backup-laboratorio.tar /home/laboratorio and then num-up.sh #!/bin/sh for tty in /dev/tty[1-9]*; do setleds -D +num < $tty done echo "Modulo numlock cargado..." Analize this if you don't understand just ask.
