Using vi-mode in your shell

In the large ecosystem of computing and operating systems, there are many shells. However, in the Linux world, the de facto standard has become bash and it is the default shell installed on all major Linux distributions at of the time of this writing. As such, that is the shell I’ll be talking about today. Something to note, though, is that bash is also a reasonably popular option on other UNIX-style operating systems, so it’s likely not far from your reach (and for you Windows users out there, there’s always cygwin).
