TABLE OF CONTENTS UNIX for OpenVMS Users, Third Edition
Chapter 4: Introductory File Management
Overview
Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them.
George Orwell
UNIX possesses numerous commands and utilities for the creation, modification, and display of files and directories. Table 4.1, a summary of filemanagement commands, was created from the headers of the man page entries for all sections of the BSD documentation (see Section 3.6). Table 4.1 divides the commands into those that display files and those that manipulate them. Since display commands do not change the contents of files, the novice user may use them in complete safety. Manipulation commands do change the contents of files, and novice users should use them with care.
