Nautilus scripting
attachment:Icone/Piccole/nautilus.png
Il file-manager di nautilus supporta lo scripting anche se in modo limitato. I seguenti file possono essere copiati nella cartella nautilus-scripts. Molti di questi scripts coinvolgono i privilegi di root, che possono danneggiare seriamente il sistema in uso.
Directory nautilus-scripts: ~/.gnome2/nautilus-scripts o /home/<utente>/.gnome2/nautilus-scripts dove <utente> è l'utente desiderato.
Disporre i propri scripts nella directory e renderli eseguibili digitando in un terminale il seguente comando:
chmod +x <nome-dello-script>
Una volta fatto questo , gli scripts saranno disponibili in tutte le finestre di Nautilus sotto la voce File -> Script, e saranno richiamabili attraverso il clic con il tasto destro.
Manda via mail il file selezionato
Questo è veramente utile per cercare un file e inviarlo per email dalla posizione in cui ci si trova:
#!/usr/bin/perl -w
# By John Russell
# This script sends the selected file(s) with your email client.
use strict;
my $MAILTO_URL="mailto:?";
my @files = split("\n", $ENV{NAUTILUS_SCRIPT_SELECTED_FILE_PATHS});
my $count = 0;
foreach my $file (@files)
{
if ( ! -f $file && ! -l $file )
{
my @dialog = ("gdialog","--title","Error","--msgbox", "\nError: Can not send $file. \n\n Only regular files can be mailed. ","200", "300");
system (@dialog);
}
else
{
$MAILTO_URL = $MAILTO_URL . "attach=" . $file . "&";
shift;
$count += 1;
}
}
if ($count > 0)
{
my @command = ("gnome-open", $MAILTO_URL);
system(@command);
}La sintassi mailto: non funziona con mozilla-thunderbird. La seguente versione sembra invece funzionare con Thunderbird:
#!/usr/bin/perl -w
# By John Russell
# and hacked to work with thunderbird by Darrell
# This script sends the selected file(s) with mozilla-thunderbird.
use strict;
my $attach_string="\"attachment='";
my @files = split("\n", $ENV{NAUTILUS_SCRIPT_SELECTED_FILE_PATHS});
my $count = 0;
foreach my $file (@files)
{
if ( ! -f $file && ! -l $file )
{
my @dialog = ("gdialog","--title","Error","--msgbox", "\nError: Can not send $file. \n\n Only regular files can be mailed. ","200", "300");
system (@dialog);
}
else
{
$attach_string = $attach_string . "file://" . $file . ",";
shift;
$count += 1;
}
}
if ($count > 0)
{
$attach_string = $attach_string . "'\"";
# replace spaces with '%20' as demanded by mozilla/thunderbird
$attach_string =~ s/\s/%20/g;
# invoke shell script to call thunderbird differently depending on whether it's running already or not
my $command = ("~/scripts/thunderbird-email-attachments " . $attach_string);
system($command);
}Nell'ultime righe dello script precedente viene richiesto il seguente script di shell, (indicato con ~/scripts/thunderbird-email-attachments. Attenzione a non posizionarlo nella directory nautilus-scripts, altrimenti sarebbe visibile nel menù contestuale):
#!/bin/sh
# if thunderbird is already running open a compose window in the running instance
if `ps xc | grep -q mozilla-thunder`; then
exec mozilla-thunderbird -a Mozilla-Thunderbird -remote "xfeDoCommand(ComposeMessage,$1)"
# else start a new instance with the compose window only
else
exec mozilla-thunderbird -compose $1

#By modprobing loop it makes sure that the module is loaded and ready for

Impostare la sola lettura sui file

Aprire Nautilus con i privilegi di root
#!/bin/bash
# root-nautilus-here
# opens a root-enabled instance of a nautilus window in selected location
# requires sudo privileges and gksudo, which may involve security risks.
#Install in your ~/Nautilus/scripts directory.
#
# Placed in the public domain by Shane T. Mueller 2001
# Fixes provided by Doug Nordwall
#
# 2004.04.18 -- keith@penguingurus.com - Added gksudo usage to provide popup
# password window if sudo has expired. Line only echos got
# root to std output. But gksudo updates your sudo access
# privs, so running nautilus with sudo will succeed
# without asking for a password.
foo=`gksudo -u root -k -m "enter your password for nautilus root access" /bin/echo "got r00t?"`
