Step 1: Download Sublime: You can either download from their website or use the wget as I did:
$ cd ~/Downloads
## On 32bit
$ wget https://download.sublimetext.com/sublime_text_3_build_3126_x32.tar.bz2
## On 64bit
$ wget https://download.sublimetext.com/sublime_text_3_build_3126_x64.tar.bz2
Step 2. Extract Sublime package (example to /opt directory) You can store Sublime at any place you want. Here, I saved under /opt directory.
## On 32bit
$ sudo tar -vxjf sublime_text_3_build_3126_x32.tar.bz2 -C /opt
## On 64bit
$ sudo tar -vxjf sublime_text_3_build_3126_x64.tar.bz2 -C /opt
Step 3. Now, let’s make a symbolic link to the installed Sublime3 so that we can run the same from command line
# sudo ln -s /opt/sublime_text_3/sublime_text /usr/bin/sublime3
Step 4. Now, let’s test whether the Sublime3 is installed correctly or not. Type sublime3 in command line and it will open up the sublime window.
$ sublime3
Step 5. Create Gnome desktop launcher You can run Sublime3 on desktop by clicking a icon.
$ sudo sublime3 /usr/share/applications/sublime3.desktop
Step 6. Append this and close file.
[Desktop Entry]
Name=Sublime3
Exec=sublime3
Terminal=false
Icon=/opt/sublime_text_3/Icon/48x48/sublime-text.png
Type=Application
Categories=TextEditor;IDE;Development
X-Ayatana-Desktop-Shortcuts=NewWindow
[NewWindow Shortcut Group]
Name=New Window
Exec=sublime -n
TargetEnvironment=Unity
Now, you can see the Sublime3 icon on under Applications → Programming. You can run Sublime3 on desktop by clicking this icon. Enjoy!!
