I'm using cygwin bash 2.05b-8 (it's actually gnu).
I thought that $HOSTNAME was an environment
variable. When I run gnu make (I'm pretty
sure this is not a make problem), $(HOSTNAME)
is empty. It gets fixed if I do "export HOSTNAME"
before running make.
Is there a way to check if the export command
has been applied to $HOSTNAME? Does the
actual transcription of $HOSTNAME's value to
the environment happen only once, when
"export" is applied, or is there a continual
monitoring an mirroring of changes to $HOSTNAME
forever after applying "export"?
