The sh shell (Bourne-like shell, actually a derivate of ash) does not have this functionality.

Hey, didn't know I had a rare '78 first ed; ANSI not even in the index.
I confess to buying it secondhand in '94 from a likely sorry bloke, and
wonder if anyone's published a diff (ono) to the 2nd ed?
But my most dog-eared, tabbed and note-stuffed reference is Kernighan &
Plauger's Software Tools in Pascal ('81) - lovely if only for quality of
the writing and typesetting. Appropriate thread for a little heresy? :)

Hardly new. It hasn't been the Next Big Thing since the '80s. Java was
the Next Big Thing in the '90s. We don't exactly have a new Next Big
Thing for the '00s, from what I can see -- and maybe that's a good thing.
Agile development is the Next Big Thing for development methodologies,
but that's a somewhat separate issue.

That's correct -- 2nd Ed is the ANSI C version of basically the same

I won't argue the point! but how about "IEEE"? I subscribed
to that for years and some people noted that spoken as a word,
"Ieee" was like the primal scream! Hm maybe the EEE

About 2000, 2001 was when I shucked my "muuz" game/mind-machine
effort. It was over 10K line of C-ish code that I rehacked into

Yeah, it's on amazon.com, but "my bible" {seriously!} is good
enough. Dog-earned and coffee-stained; but it's the same as the

Trivia: BCPL was the _first_ programming language to use 'curly braces' to group statements. It also used '//' to indroduce a 'single-line comment'. >Someone > (at Bell Labs?)

I have done some projects using BCPL... in a mainframe (S370) running MVS in the 70's... it was lightning fast. we had made a kind of TSO (time sharing option) that runs on top of VTAM, to bring "online compile and run" cobol programs to the desktop... while a batch work responds in 3 hours, a TSO (written in bcpl) responds in seconds... Thanks for remember the "good old days" ... it is still active!!! => http://www.cl.cam.ac.uk/~mr10/BCPL.html Sergio ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
