By "run it from the start" I guess you mean the Unity launcher, the dash
.
The best way is to create a .desktop
launcher, first open a text editor, for example
gedit
Now copy this in to the file
[Desktop Entry]
Name=slic3r.desktop
Exec=./slic3r.pl
Icon=/path/to/your/icon
Type=Application
Terminal=false
Now save this as slic3r.desktop
in your home directory and open a terminal and make it executable with
chmod +x ~/slic3r.desktop
Now double clicking this icon will run your program, to get it to appear in the dash
like a normal application, move it to .local/share/applications
mv ~/slic3r.desktop ~/.local/share/applications
You can now search for slic3r
in the dash, to add an icon change /path/to/your/icon
for the path of the icon you would like.
Applications you build your self (or script programs) don't get an entry of there own in the dash
, you can apply this to any program to create a launcher for it.
