UNIX(R) System V Release 4: An Introduction

One of the most valuable features of the UNIX(R) system is the rich set of commands it gives you. This chapter surveys a particularly useful set of commands that are often referred to as the UNIX tools. These are a collection of small, modular commands each of which performs a specific function, such as sorting a list into order, searching for a word file, or joining two files together on a common field. You can use them singly and in combination to carry out many common office tasks.
