PATH

This variable is set to a default value when you start the MPE/iX Shell. Normally, it is

also set in your proﬁle ﬁle. It lists the directories that are to be searched to ﬁnd com-

mands, as described in sh(1).

SHELL

This variable contains the full path name of the shell being used.

TERM

This variable contains the terminal type.

TMPDIR

By default, MPE/iX Shell and Utilities commands store temporary ﬁles under /tmp.

To use a different directory for temporary ﬁles, set

TMPDIR

to the name of the direc-

tory you want to use.

Commands that print times (and dates) use this variable to determine the time zone.

The

variable is normally set in the /etc/profile ﬁle for system-wide use.

See timezone(3) for details.
