Install the following programmes:

Linux Terminal $:

sudo apt-get install cuetools shntool flac

Split the audio file in the following manner, required commandline first followed by an example:

Linux Terminal $:

cuebreakpoints file.cue | shnsplit -o flac file.flac

cuebreakpoints Skyscraper.flac.cue | shnsplit -o flac Skyscraper.flac

Thanks go to Danilo Dellaquila for the above tutorial.
