HELP(1)                 System General Commands Manual                 HELP(1)

NAME
     help - help for new users and administrators

DESCRIPTION
     This document is meant to familiarize new users and system administrators
     with Interix and, if necessary, UNIX in general.

     Firstly, a wealth of information is contained within the system manual
     pages.  In UNIX, the man(1) command is used to view them.  Type man man
     for instructions on how to use it properly.  Pay especially close atten-
     tion to the -k option. You may also be interested in the apropos(1) com-
     mand.

     Other Interix references include the FAQ (Frequently Asked Questions)
     located at http://www.interix.com/tools. There are also Forums and news
     groups where questions are fielded by Interix developers and other users;
     see http://www.interix.com/tools.

   The Unix shell
     After logging in, some system messages are typically displayed, and then
     the user is able to enter commands to be processed by the shell program.
     The shell is a command-line interpreter that reads user input (normally
     from a terminal) and executes commands.  There are many different shells
     available; Interix ships with csh(1), ksh(1), and sh(1).  Additional
     shells can optionally be installed such as bash(1), zsh(1) and scsh(1).
     Each user's shell is indicated by the last field of their corresponding
     entry in the system user database. You can view this setting with the
     finger(1) command and change your default shell with the chsh(1) command.

   Basic Unix commands

     man     Interface to the system manual pages.  For any of the commands
             listed below, type man  for detailed information on what
             it does and how to use it.

     pwd     Print working directory.  Files are organized in a hierarchy (see
             hier(7)) called a tree.  This command will indicate in which
             directory you are currently located.

     cd      Change working directory.  Use this command to navigate through-
             out the file hierarchy.  For example, type cd / to change the
             working directory to the root.

     ls      List directory contents.  Type ls -l for a detailed listing.

     cat     Although it has many more uses, cat filename will print the con-
             tents of a plain-text file to the screen.

     mkdir   Make a directory.  For example, mkdir foobar.

     rmdir   Remove a directory.

     rm      Remove files.  Files are generally only removable by their own-
             ers.  See the chmod(1) command for information on file permis-
             sions.

     chmod   Change file modes, including permissions.  It is not immediately
             obvious how to use this command; please read its manual page
             carefully, as proper file permissions, especially on system
             files, are vital in maintaining security and integrity.

     cp      Copy files.

     mv      Move and rename files.

     ps      List active processes.  Most UNIX-based operating systems,
             including Interix, are multitasking, meaning many programs share
             system resources at the same time.  A common usage is ps -Al
             -Xunix, which will display information about all active Interix
             processes.

     kill    Kill processes.  Used mostly for terminating run-away/unrespon-
             sive programs, but also used to signal programs for requesting
             certain operations (i.e., re-read their configuration).

     date    Print the current system date and time.

     mail    Access mailbox.

     logout  Log out of the system.

     When a command is entered, it is first checked to see if it is built-in
     to the shell.  If not, the shell looks for the command in any directories
     contained within the PATH environment variable (see environ(7)).  If the
     command is not found, an error message is printed.  Otherwise, the shell
     runs the command, passing it any arguments specified on the command line.
