Sending Commands to a Remote Computer

You must connect to a remote computer before you can execute commands on it. You can send commands to a remote computer using:

ÂSecure Shell (SSH), a tool for logging in to a remote computer and for executing commands on a remote computer.

ÂTelnet, a tool for communicating with another computer using the TELNET protocol.

See Chapter 2, “Connecting to Remote Computers,” on page 31 for information about sending commands to remote computers.

Viewing Command Information

Most command-line documentation comes in the form of man pages. These are formatted pages that provide reference information for shell commands, tools, and high-level concepts. You can also access command information using the help command, and sometimes information is displayed if you enter the command without any parameters or options.

To access a man page:

$ man command

where command is the topic you want to find information about. The man page contains detailed information about the command, its options, parameters, and proper use. For help using the man command, enter:

$ man man

If the man pages are so long that they do not fit on your screen, you can use the more or less command to automatically paginate the file. This allows you to view the file faster by loading full screens of the man page at a time, rather than the entire file.

$ man serveradmin less
