As is one can tell from the dates on my posts, I spent a while tracking this one down. The original link is in a now inaccessible e-mail account so I went out and located it directly on the web. The date of the manual is in 2010 so it looks as though it is being kept relatively up to date.
For those interested in why I am posting this particular link, the reason is simple. BASH is the shell used by OS X and one of the shells used by Linux/BSD. It ties in with the shell programming articles I’ve written recently. This link is to the reference guide/manual for the shell. All those Apple// folks who ended up with Macs can now start programming again. 😉
Incidentally to view the manual on-line the second of the first group of links is the best place to start.
