Now that we’ve covered some basic shell commands, let’s shift focus a little and talk about some of the features that bind those commands together into a useful working environment. In this guide, we’ll cover:
standard input and output
combining commands with pipes
redirecting output to and from files
standard error and exit codes
While these may sound like dry topics, it’s here that the command line begins to come into its own as a tool and environment for solving problems. Pull up a terminal and read on!
As ever, feedback on these would be much appreciated.
