MPE/iX Shell and Utilities Reference Manual, Vol 2

Invoking the MPE/iX Shell from the CI Prompt
MPE/iX does not currently implement MPE/iX Shell as a system login shell. As a result, you must specify
the –L option when invoking the
MPE/iX Shell from the system prompt. This ensures that the shell
reads and executes the required configuration information files.
At startup time, the MPE/iX Shell searches for a .profile file in the directory specified by the HOME
environment variable. When you invoke the
MPE/iX Shell with the –L option, the HOME variable is set
to your current working directory. If your current directory is not your home group, your current shell
session does not load your .profile file and may instead load somebody else’s .profile file.
In addition, when you invoke the
MPE/iX Shell, it tries to open the file .sh_history which contains
the command history. Any other shell executing from the same directory shares your history file.
For these reasons, it is important to make sure that you start the MPE/iX Shell from your home group so
that you do not interfere with other users.
Typically, your system administrator assigns you a home group when your user identity is first esta-
blished on the system. To determine your home group, enter the following at the MPE/iX CI prompt:
LISTUSER
Contact your system administrator if you do not already have a home group.
