Installing Procps

Installation of Procps

Install Procps by running the following commands:



make &&
make XSCPT='' install &&
mv /usr/bin/kill /bin

Command explanations

make XSCPT='' install: This will set the Makefile variable XSCPT to an empty value so that the XConsole installation is disabled. Otherwise "Make install" tries to copy the file XConsole to /usr/X11R6/bin. And that directory does not exist, because X is not installed yet.
