LKP System Management

Commands

When you are operating in Linux mode you can execute the Linux version of most standard commands. Command options and output are sometimes different, but most commands are functionally similar to UNIX. You can use most user commands (ls, cat, etc.) freely, but you should not use commands typically reserved for administrators (shutdown, mount, fsck, and so on) in Linux mode.

The RedHat Package Manager (RPM) is used to manage software packages in the LKP environment. See ``RPM commands''.

The Linux command

The linux command switches from UNIX mode to Linux mode by executing a Linux shell for the user executing the command. This is the recommended method of changing mode because it sets up the user's Linux PATH and other environment variables properly. To exit Linux mode and return to UNIX mode, type <Ctrl>-D.

NOTE: If you are the root user, the linux command switches you into Linux mode, but it does not change directory. You must cd to the directory you want to be in.

The linux command is a wrapper, located in the /unixware/usr/bin directory.

If the LKP is disabled because of auditing, the linux command fails with the following message:

   The system administrator has disabled Linux Kernel Personality support
   for the purpose of auditing system activity.
