Programming for the Command Line
Chris F. A. Johnson · Apress eBooks · 2009
This book is about programming with the shell, not about using it at the command line. You will not find information about editing the command line, creating a command prompt (the PS1 variable), or retrieving commands from your interactive history. This chapter is about scripts that will mostly be useful at the command line rather than in other scripts. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
