Subject: "make"ing MPE programmers Posix portable :-)

Charge:
 
After reading books on Posix programming - browsing Shell and Utilities
guides and make books - my head aches.
 
There is one overall lacking feature in all these books (that I learned in
marketing 101):
 
  "Customer will retain squat unless related to something familiar."
 
I would like to start a two column thread - MPE on one side - Posix on the
other.  The idea is to list a well known MPE command or function and map
that into the Posix equivalent.
 
OK, lets start simple - common everyday things.  This could get quite large
but it would be useful for first timers (probably need combinations of shell
commands to equivalent most MPE commands).
 
 MPE:                                SH.HPBIN.SYS -L (POSIX):
-----                                ------
CHGROUP pub                          cd ../PUB
SHOWME                               pwd, who, ???
COPY filea,fileb  (filea is FILEA)   cp FILEA FILEB  (filea _is_not_ FILEA)
EDIT                                 vi
SHOWJOB                              who
PRINT                                more
LISTF @                              ls -lsa
LISTF @.@                            ls -R
ECHO                                 print, echo
FILE                                 ???
BUILD                                ???
REDO                                 r
 
     SHOWME                             whoami or who am i
Ok, my watch says 5:00pm - anybody please feel free to add your favorites
(you're right - I'm starting a group effort here).  Lets not get into
subsystems like vi for now (chapters).
 
Any pointers to other sources along these lines very welcome!
