Sometimes instead of running several sessions of SSH’s or putty’s, I run Emacs with multiple shells– this cuts down on the number of windows I have to deal with.
To run a shell in Emacs, you invoke the Lisp function “shell” via meta-x shell. This creates a buffer called *shell*. Running it the second time though doesn’t create a 2nd shell buffer as you might expect, instead it brings you back to the original shell buffer. The trick is to rename the original buffer to avoid name collision. The quickest way to do this is via “rename-uniquely" function via meta-x rename-uniquely. It renames the buffer to a similar but unique name like "*shell*<2>“. Now if you start another shell.
The better behavior is for Emacs to automatically create new buffer with unique name. Perhaps there’s a hook to configure this that somebody can point me to.
