SCID is a free, cross-platform chess database application. Can be used to edit PGN files and do loads of other stuff.
Unfortunately there is no PPA or deb files available to install the app in Ubuntu, so you have to get the tarball available at the site and install manually. If you try to configure the tarball you’ll get an error saying that it cannot find Tcl and Tk in the system, even though you have Tcl/Tk installed. The reason is you need to have the developer channels of Tcl/Tk installed for SCID.
Here’s how to install SCID in Ubuntu:
1. Install Tcl/Tk developer channels using the command:
sudo apt-get install tcl8.5-dev tk8.5-dev
(8.5 is the latest release)
2. Download the SCID tarball and extract in a temporary location
3. Go to the extracted location in a terminal and enter the following commands:
sudo make install
To run SCID, press Alt+F2, type scid and press enter.
