Are there VMS commands which are equivalent to the following UNIX commands? These are command lines for sh. $ do something; do something else; ..... $ do this & $ something > somewhere $ all >& somewhere Thanks, Tad -- Tad Marko ..!ihnp4!killer!tad || ..!ihnp4!alamo!infoswx!ntvax!tad UNIX Connection BBS AT&T 3B2 North Texas State U.

Are there VMS commands which are equivalent to the following UNIX
commands? These are command lines for sh.
Well, if you get the DEC Shell layered product, which contains the Bourne
shell, you can type EXACTLY what you have below. Failing that...
$ do something; do something else; .....
No direct analogue - DCL is one command per line. (You could define a command
procedure, say DO, which took a bunch of commands and executed them, using
some format like DO command \ command \ command.)
$ do this &
SPAWN/NOWAIT this. (If "this" tries to interact with the terminal, strange
things will happen - there's nothing like job control. Output is not a big
deal - acts just like Unix, actually; input will go to one or another of the
active processes pretty much unpredictably if you do this.)
$ something > somewhere
No direct analogue. Many commands have a /OUTPUT:somewhere qualifier which
does pretty much the same thing. The general idiom takes two lines:
$ assign/user somewhere SYS$OUTPUT
$ something
$ all >& somewhere
This re-directs error output, as I recall. Same as for the above, with
SYS$ERROR in place of SYS$OUTPUT.
