Run notepad++.exe from terminal

If the file you are trying to create or edit does not require root privilege, run this:

wine /home/jon/.wine/drive_c/Program\ Files/Notepad++/notepad++.exe

If it does require root permission at all, install the notepad++ with your root account after having been logged in as root (e.g. by executing sudo -s -H), log out, and run:

sudo wine /home/root/.wine/drive_c/Program\ Files/Notepad++/notepad++.exe

But usually, as has been pointed out, running wine applications as root is not recommended since wine apps rely on wine and the source code of wine apps may or may not be reviewed, meaning there is an increased amount of risk involved in doing so.

Here are a generic ones:
(Just copy paste on Terminal, & press ENTER key)

For Ubuntu x64 OS:

wine /home/$USER/.wine/drive_c/Program\ Files\ \(x86\)/Notepad++/notepad++.exe

For Ubuntu x86 OS:

wine /home/$USER/.wine/drive_c/Program\ Files/Notepad++/notepad++.exe

If you dont know if your ubuntu is x86 or not, then type both above, one after the other, one will work.

Best of luck

The space in the filename/path may be the main issue.

sudo /home/jon/.wine/drive_c/Program Files/Notepad++/notepad++.exe

should be:

sudo wine "/home/jon/.wine/drive_c/Program Files/Notepad++/notepad++.exe"

and I do believe you must tell wine what exe to run.
