sh ∗cpl.shYou may need to close and re-open the Debian window before the newly installed commands become available at the command prompt. You can open as many Debian windows as you like; for instance, one to edit and one to execute your own CPL program.
You are all set!
Notice about graphics: Microsoft's Windows Subsystem for Linux provides a terminal-only experience of a Linux distribution, deprived of its graphical user interface. The CPL compiler, interpreter and editor are all built to run in a terminal and will fit in seamlessly, but if your CPL program draws graphics and needs the additional
gnuplot package, installing it via Debian (as
apt install gnuplot) will not do. Instead you may want to install the Windows version of gnuplot, available from the official gnuplot site, and then
ln -s '/mnt/c/Program Files/gnuplot/bin/gnuplot.exe' bin/gnuplot
in your Debian terminal, and CPL programs will automatically find it too.
