I've just installed Ubuntu so that I can install the Starlink astronomical data analysis tools, and I'm stuck on one of the installation steps:
"7.If not yet available, install the following packages (which are required by some of the Starlink software): 1. csh "
How do I check is "csh" is 'available'? If it isn't, where do I get the package "csh"? And when I have downloaded it, where should I put it? In /star-namaka/lib/ or somewhere else?
