problem when trying to make another file manager default

[Guest nocando]

Hi,

created a problem when tying to get the pcmanfm file manager set as default.

using ubuntu 14.04 and added gnome fashback, was logged in using the gnome flashback (compiz) desktop.

set the desktop up to be similar to windows.

wasnt happy with the file manager and installed various file managers to test which would be preffered.

decided that pcmanfm was the best option to use as the default file manager.

now needed to make it the default file manager.

came across this code to make another file manager defaiult

 

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

sudo ln -s /usr/bin/pcmanfm /usr/bin/nautilus

 

ran the code in the terminal window and had an OOps! moment

now the problem occured because i remembered that nemo ended up becoming the default when installing it, while all the others needed to be run to use them but not automatically becoming the default.

 

so tried another variation of the script even though i dont have a clue to what it actually does.

 

sudo mv /usr/bin/nemo /usr/bin/nemo.bak

sudo ln -s /usr/bin/pcmanfm /usr/bin/nemo

 

rebooted and the gnome flashback compiz desktop was black, no icons but the task bar remained.

 

ended up unistalling all the installed file managers except for nautilus, as it stated that there were critical files need for ubuntu to run.

 

rebooted, the desktop was still the same.

now when clicking on documents in the "places" menu, audacious came up as the default file manager, which was most likely due to there being no default file manger in the stystem.

(seemed to be an ok file manager though a little complicated trying to listen to the files and verbally navigate to the correct files- prefered it over nautilus ! )

 

luckily i had another file manager (commader) which allowed me to open the saved text file containing the script above.

again tried a few variations to get nautilus back as the default without any luck

decided to uninstall nemo-rebooted and still the same problem.

reinstalled nemo - rebooted and the desktop came back to normal, icons and all.

 

unfortunately now when using nemo, the title bar ( file edit veiw etc) are on the bottom taskbar- (not on the actual bottom of the file manager window, on the actual taskbar and the text was repeated twice on the lower taskbar.)

so something was corrupted.

 

is there any way to safely get nautilus back as the default file manager

and then install and make pcmanfm the default.
