Always remember that PEAR has a help command:
$ pear help .. list of commands follows ..
Command examples will have a dollar sign $ before each line that is typed. This helps to distinguish input from the output of the PEAR installer.
$ is just an example for a command prompt. Depending on your distribution or personal preferences, your shell might display a username, often combined with the current path: joe:~/some/path>
Help for a command is just as easy to get:
$ pear help <command> $ pear help install .. help for install follows ..
