I installed Cygwin (including its perl distro) but Cygwin's bash shell is unable to find perl (bash: perl: command not found) - and I can't find it either. Having nominated E:/cygwin as the "root" directory, I expected to find perl somewhere under E:/cygwin/usr, but it's not there. If I rerun setup and select to install Perl, I get the message that there is nothing to install (which I take to mean that as far as setup is concerned, Perl is already installed.)
How do I get rid of my current Cygwin installation so that I can install again from scratch ? (Is simply deleting the E:/cygwin directory sufficient ? I've tried that but it hasn't helped.)
