Control-R, my favorite Unix shell command

Control-R will work with anything that uses readline and keeps history. In addition to working in the Unix shell, it also works in psql (the PostgreSQL tool) and the Python REPL.

It's a very useful trick to keep up your sleeve!

Tip for rbenv users on OSX... install readline with homebrew and install your ruby versions with:

    SKIP_PRECOMPILED_RUBIES=1 CONFIGURE_OPTS="--with-readline-dir=$(brew --prefix readline)" rbenv install (version)

to get readline working for irb/pry (for ctrl+r search, etc.)

You can also use "rlwrap" with any program to enable readline features.

Python REPL?

Is there something I need to do to enable that?

The Python REPL that I'm using has readline enabled. If you don't have it you may need to rebulid it and enable readline when you run configure.

Note that a given python may be compiled without readline or with a readline replacement.

Yeah, the one on OSX isn't compiled w/ readline. But I tried it on a ubuntu host and it works.
