I have Mac Lion, I was trying to install Emacs 23.3 using these instructions and others.
Emacs 23 didn't work, and I lost the one that was already there (emacs 2. something). Now, when I type: emacs in the terminal, I get: -bash: Emacs: command not found.
Can anyone instruct me how to get it back?
Emacs: command not found? Tryemacsin lower-case; commands in the terminal are case-sensitive. – Lindydancer Nov 24 '11 at 11:03
