I agree. I once wrote a whole set of functions to run sql and sqlplus scripts
directly from the command line. I didn't find it useful enough to continue.
And it's rather tricky to program.

Subject: RE: PERL? |
I've written one shell script using the coprocess. I don't like using it.
But that's just me.
I think one way of describing ksh (for the male readers out there, anyway)
is that ksh is like the "legally blonde" girlfriend: There are times when
you wish there was more intelligence there. But she has enough features to
satisfy; and she's so easy, you just going back to her.
