Re: Piping and Redirection

["Dennis Lovelady" <dlovelady@xxxxxxxx>]

For the record, OVRDBF ... TOFILE(...) is precisely what redirection is
about.

But it stops there, unfortunately.

Piping is the ability to stream the output one process as the input of
another.  On the AS/400 (ignoring QSH if I may be so bold), this simple
example:
    sed 's/a/b/g' filename | grep 'any' | tee def | more

would be executed something like this (assuming that sed and grep and tee
actually exist)   :

ovrdbf input TOFILE(filename)
ovrdbf output TOFILE(qtemp/stream1)
call sed 's/a/b/g'
ovrdbf input TOFILE(qtemp/stream1)
ovrdbf output TOFILE(qtemp/stream2)
call grep 'any'
ovrdbf input TOFILE(qtemp/stream2)
ovrdbf output TOFILE(def)
call tee
/* (existing overrides will suffice here...) */
call more

Kinda loses the beauty and simplicity.

You mean like OVRDBF INPUT and OVRDBF OUTPUT on the FTP command?

You say that is if it didn't start in the in the land of opinion...

PS - For the record, I like the consistency of OS/400's command naming,
but I
also really like the ability to use piping and redirection.  Now if we
could
just have the best of both worlds...
