Re: iGlobal variable not updated in while loop when reading from pipe

[James Wiegand]

Sorry for the confusion, Paul.  I did not realize that the value of $$ did
not change in a sub-shell.  My first thought was that there was a subshell,
but when I tried to test that idea, I looked at the value of $$ which did
not change.

Thanks for the prompt reply!

See entry E4 in the bash FAQ.
