Philip,
Sweet! I just got a chance to try it out. In reading the AIX docs, I think
I understand what is going on here, but I am a little uncertain about the
double-dash. Is the following correct?
!& creates the co-process or piped background process.
cat <&p & creates the background job that redirects all the co-process ouput
to the 'cat' command, which gets output to my display.
print -p -- writes the argument enclosed in quotes to the co-process.
The part I'm not completely sure about is the double-dash (--). The AIX man
page for ksh is very sparse. I went to
publib.boulder.ibm.com/.../korn_shell_enhanced.htm under "Coproces
facility", but didn't find any help there. I did find some info under the
getopts command that makes me think the double-dash is just a kind of
terminator that says "don't check for any more options after -p. Is that
correct?
Thanks,
David
