Come formattare le date da visualizzare in una shell Linux

Posted by: (apr 19)

Nella shell si può specificare il formato della data nel seguente modo:
date +FORMAT

Ad esempio digitando:
$ date +"%m-%d-%y"

Si ottiene:
04-17-10

 

Se si vuole l'annoa 4 cifre:
$ date +"%m-%d-%y"

Si ottiene:
04-17-2010

 

Per ottenre l'ora corrente basta digitare:
$ date +"%T"

Si ottiene:
19:55:04

Per ottenre l'ora basata sulle 12 ore:
$ date +"%r"

Si ottiene:
07:56:05 PM

Per visualizzare l'ora nel formato HH:MM:
$ date +"%H-%M"

Si ottiene:
07:56

Come montare condivisione Windows in Linux

Posted by: (apr 19)

Per visualizzare le condivisione attive consiglio di fare prima questo comando:

smbclient -L <windows-box> -U <username>

 Dopo possiamo procedere a mappare la condivisionewindows nella nostra linux box nel segunete modo:

  1. Creare la directory per il mountpoint: mkdir /mnt/<name-of-mount-point>
  2. Montiamo il windows share share:
    mount -t cifs -o username=<username>,password=<password> //<win-box>/<share> /mnt/<name-of-mountpoint>
    Note: The syntax -username=<username>,password=<password> saves the password.
  3. Infine se volete potete creare il link simbolico al drive: ln -s /mnt/<name-of-mount-point> /<path-of-symlink>
