I would be inclined to say that "show system"
is more equivalent to "ps" than is monitor,
especially when you consider that many folks
who want to read the doc will telnet or ssh
into a VMS system using an xterm with marginal
SET TERMINAL settings hence lousy SMG$
and MONITOR support. On the other hand MONITOR
is useful to know hence this list could be
a one to many or many to many mapping.
Another problem with such lists is the
unknown customization that typically takes
place. I have yet to come across a VMS
shop where then was not some form of "cd :== @dir:cd.com"
symbol in use heavily by folks who cannot
stand to learn how to use SET DEFAULT.
There are a myriad number of cd.com cd
emulators some with better unix emulation than
others. You could wind up documenting the quirks
of whichever one you are familiar with rather than
the one in use by someone else.
However, I don't want to sound too discouraging.
The effort no matter hwo difficult or subtle is
probably well worth it.
In fact I'll add a few commands:
LINUX: VMS:
man help
grep pattern file search string filespec(s)
cd directory set default [.directory]
lsof show devices /file
cc -c -switch cc /qualifier
link
. (sh, bash) @
source (csh, tcsh) @
at submit/after=time
date show time
pwd show default
exit logout
Perhaps this list could be converted to pod or
html and posted at www.vmsperl.org?
Or perhaps we should just invert one of the
other Unix for VMS user html docs already
out on the net?
