How to create a permanent launcher icon for Knime in Ubuntu Linux (22.04 in my case, but should work in most other recent versions too). Open a terminal window and enter:
pico ~/.local/share/applications/KNIME.desktop
and paste
[Desktop Entry]
Type=Application
Version=1.0
Name=KNIME
GenericName=KNIME Analytics Platform
Comment=KNIME Analytics Platform
Exec=/path/to/knime
Icon=/path/to/icon.xpm
Terminal=false
Categories=Development;IDE;
StartupNotify=true
into it. Change “/path/to” to wherever the downloaded Knime archive was unpacked. Save (ctrl-O) and exit (ctrl-X). Reboot and login again. Click on “Show applications” in the bottom left corner. It should show the Knime icon. Right-click the Knime icon and choose “Add to favorites”.
