Knowledge of UNIX commands provides a good foundation for understanding UNIX and is critical to success as a power user or system administrator.

Control characters such as Control-c, Control-d and Control-u are used in the UNIX environment to perform special functions such as interrupting command output, logging out and clearing screen entries.

There are a number of file information commands available. These include the file, strings, cat, more, head, tail, wc and diff commands. They can be used to find out information about the type and characteristics of a file as well as its contents.

When creating new files and directories, you should adhere to the naming conventions. These are the basic rules for naming files and directories which include length and recommended characters.

New directories are created using the mkdir command and new files are created using the touch command. Files and directories can be removed or deleted using the rm command

CDE File manager is a graphical utility you can use to perform many of the same functions as the file and directory management commands entered at the command line.
