Problem description

There are several functional differences between the Bourne shell (sh) on Tru64 UNIX and the POSIX shell (sh) on HP-UX.

Examples of differences include support for varying environment variables, including USER; initialization procedures for some environment variables; variable name limits; default export behavior for variables in the initial environment; and reserved file descriptors.
