HOWTO: replace Nautilus by Rox filer in Gnome

[Laurent Cazalet]

I like Gnome, but I'm always annoyed by Nautilus. And when you use Gnome, Nautilus gets in your way all the time, while I prefer a lot the agile Rox filer.

Here's a way to combine the best of both.

This script aims to transparently use Rox filer instead of Nautilus.
This HOWTO also gives a method to mount Gnome-VFS drives onto the system so that they are available to non-Gnome programs (like Rox filer).

Objective:

Rox filer (or another file manager) runs as a transparent replacement of Nautilus everytime the system calls /usr/bin/nautilus. This is a user-specific hack. It doens't affect other users of the system.

In particular in the following cases
- open folder from Places menu and panels
- open automatically mounted media (CDROM, usb drive etc...)
- open trashcan clicking from Gnome panel (if TRASHDIR is set)
- "open folder" when called from Search dialog box
- open network drives (if Fuse and another tools are installed, see advanced topic below)

Opens normally Nautilus if:
- the environment variable NAUTILUS_REPLACEMENT is not set
- Nautilus browser mode is requested (--browse flag) (independant from settings)
- click on computer, network servers entries in Places menu
- open network drives from Places menu (if fuse not configured)
- click on trash applet and env. var. TRASHDIR is not set
- Nautilus is configured to draw the desktop and you click on desktop icons (not a feature of the script, though

As a side note,
- You can still have Nautilus draw the desktop
- drag-and-drop to trash applet works okay from Rox.


But...
- under Metacity (standard Gnome window manager), Rox filer often opens new windows beneath the active window. workarounds if it's to annoying: use xfwm4 or openbox window manager.
- (minor) Opening Home Folder from the Places menu works fine but gives visual notification timeout
- if Nautilus gets updated, the script will have to be reinstalled.

Installation
Five easy steps

1: install rox filer

sudo apt-get install rox-filer

2: Set nautilus aside

sudo mv /usr/bin/nautilus /usr/bin/nautilus.bin

3: Save this script as /usr/bin/nautilus (you must be root)

#!/bin/bash
#replacement/wrapper for nautilus
# also mounts network drives using gnomevfs-mount (using fuse)
# doesn't check if already mounted

NAUTILUS=/usr/bin/nautilus.bin
DEBUG=0
# backup our args list
ARGS=$@
ARGSCOUNT=$#

# call nautilus, with all args received in input
function run_nautilus() {
    [ $DEBUG != 0 ] && echo "OUT: Running Nautilus" >> $HOME/nautilus_wrapper.log
    exec $NAUTILUS $ARGS
}

# calls the replacement, only arg must be an existing dir
function run_replacement() {
    [ $DEBUG != 0 ] && echo "OUT: Running $NAUTILUS_REPLACEMENT. Args: '$@'" >> $HOME/nautilus_wrapper.log
    exec $NAUTILUS_REPLACEMENT $@
}

# make a directory where to mount our network drive
function makemountdir() {
    # get the server part of the URI
    SERVER="`echo \"$1\" | sed -e 's/^(https\|http\|sftp\|ftp\|ssh)//' -e 's/:\/\///' -e 's/.*@//' -e 's/\/.*//'`"
    MOUNTDIR=$MOUNTROOT/$SERVER
    [ $DEBUG != 0 ] && echo "...: Mounting $1 on $MOUNTDIR" >> $HOME/nautilus_wrapper.log
    mkdir -p $MOUNTDIR
}

[ $DEBUG != 0 ] && echo "IN: $0 invoked with '$@'" >> $HOME/nautilus_wrapper.log

# if this user didn't configure a replacement, just give way to nautilus
if [ -z "$NAUTILUS_REPLACEMENT" ]; then
    run_nautilus
fi


# loop through all args to see if one of them requires
# that we run nautilus
while [ -n "$1" ]; do
    case "$1" in
        -c|--check) ;;  #ignore
        -g) shift ;;  #ignore, and ignore next one
        --geometry) ;;  #ignore
        --no-desktop) ;; #ignore
        --sm-disable) ;; #ignore
        -n|--no-default-window)
            # run nautilus if not asked for anything else
            #if this is the only argument, start nautilus
            # this happens when nautilus is asked to draw the desktop
            if [ $ARGSCOUNT == 1 ]; then
                run_nautilus
            fi;;
        --sm-client-id) run_nautilus;;
        -? | --help) run_nautilus;;
        --usage) run_nautilus;;
        --browser) run_nautilus;;
        -q|--quit) run_nautilus;;
        computer*) run_nautilus;;
        network*)  run_nautilus;;
        trash*)
            if [ -z "$TRASHDIR" ]; then
                run_nautilus
            else
                run_replacement "$TRASHDIR"
            fi;;
        file*)
            # turn the file:/// URI into a filesystem path,
            FILE="`echo \"$1\" | sed -e 's/^file:\/\///' -e 's/%20/\ /g'`"
            run_replacement "$FILE";;

        ftp* | sftp* | http* | smb* | ssh* )
            #if we can mount this network dir through
            # Fuse and gnomevfs-mount, do it
            if [ -e /usr/bin/gnomevfs-mount ] && [ -n "$MOUNTROOT" ]; then
                makemountdir "$1"
                /usr/bin/gnomevfs-mount "$1" "$MOUNTDIR"
                run_replacement "$MOUNTDIR"
            else
                run_nautilus
            fi;;
        *)
            # unknown arg. if it's a filesystem object, use replacement
            # otherwise give up and start nautilus
            if [ -e "$1" ]; then
                run_replacement "$1"
            else
                [ $DEBUG != 0 ] && gmessage "$0 $ARGS" &
                run_nautilus
            fi;;
        esac
        shift
done

#default: open home dir
run_replacement $HOME
exit 0

4: change ownership and make this script executable

sudo chown root.root /usr/bin/nautilus
sudo chmod a+x /usr/bin/nautilus

5: Add this to ~/.gnomerc
So that changes affect only users that want it.

NAUTILUS_REPLACEMENT=/usr/bin/rox
TRASHDIR=$HOME/.Trash
export TRASHDIR NAUTILUS_REPLACEMENT

Advanced topic
Icing on the cake: Fully take advantage of Nautilus network drives (using gnome-vfs) with any non-Gnome programs like Rox filer.

Not a full how-to, but it should be straightforward.

- compile and install fuse kernel module and library (http://fuse.sourceforge.net/)
(haven't tested the ubuntu package)
- compile and install gnomevfs-mount from http://gnomedesktop.org/node/1981/31756
be sure to --enable-keyring when running ./configure
(ask me for a deb package if you need to)
- add this to your ~/.gnomerc (create it if it doesn't exist)

MOUNTROOT=$HOME/mnt
export MOUNTROOT

Configure your network drives from the Gnome interface, as you would normally do.

Enjoy automounting of those drives to $HOME/mnt/<server>
Clicking on the net drive from the Places menu mounts the drive and opens
rox-filer at the correct location.

To unmount those drives, call

gnomevfs-umount $HOME/mnt/<server>

(I added a link to this command to the mountpoint send-to of Rox filer)

Usual disclaimer: I'm not responsible if you **** your system up.

whats the difference between rox and nautilus? where can i read more about it? i really dont know this app...

I know rox is faster than the speed of light, but, I'm also curious (i never used rox.. just a bit).

Why should I use it instead of the beloved nautilus ? Why is it so much better ?

Not a flame but I wonder the same thing.

[Mr. Electric Wizard]

The only thing I don't like about Nautilus is the fact that it opens a new "window" when you drill down through a directory.
It would be nice if you could keep this from happening and have only the "active" window open.
I hate when I drill down, the child directory is always really tiny, and I have to resize it...

Open nautilus -> Edit -> Preferences -> Behaviour -> Select 'Always open in browser'
et voila!

I might have some of the names wrong (since I run Ubuntu in Dutch) but you should be able to figure it out. Also, when you have that, you can set the left panel to 'tree' so you get something that looks like Explorer on Windows.

Exactly. That's the "fix" for Spatial nautilus introduced in Gnome 2.6.

Any other reason why I should use rox ?

[tread]

Also, are file extensions registered as well as in nautilus?

Well, I'm not considering the move, but ROX is fast as lightning. It's not the prettiest thing, but it's fast as lightning.

I don't see the point of using ROX unless you want to commit to the full-meal deal: ROX-Desktop, the Pinboard, App dirs, etc. Otherwise it's just a second-rate Finder-ish filemanager, IMHO.

This might be a nice thing to do with xfce on a low-resources machine, maybe. *shrug*

[Laurent Cazalet]

Well...
This howto is not meant to be a Rox filer advocacy. Look at http://rox.sourceforge.net/phpwiki/index.php/ROX-Filer for features.
It's meant to help people who like the fast, handy, flexible Rox filer to have the choice to use it instead of Nautilus. I just wanted to publish my script and give them the choice.

For the rest, it's all a matter of personal taste and perception.
My subjective perception is: not only Rox filer is fast as hell and uses drag and drop extensively, but it also comes with a lot of handy features and is a full gtk2 application (integrating pretty nicely with gnome desktop), which make you forget the command line for ever. And Nautilus is awkard and takes way too long to open and work with, for an application that should be unobstrusive.
On slow machines, you really feel the difference, and if Gnome in itself is usable and a slick integrated environment, Nautilus is a real hassle to work with.

The pros I find in Rox filer may be cons to you. It's just like if you asked "why should I use xfce instead of gnome?". Just try it, this is the freedom of choice.
