RE: help creating a makefile that shows my current ip address

[Brown, Michael]

Wild stab:
SERVERIP=$(shell getent hosts `hostname` | cut -f1)
all:
     @echo -n "set serverip "
     @echo $(SERVERIP)

Notice the lack of spaces surrounding the = sign.  Don't remember if it makes a 
difference with make, or not.
We use the shell command here at work, but don't pipe within the command, so I 
don't know is that is where it is breaking, or not.
