Otherwise, perphup looks for a value in the environmental vari- able PERP_BASE. If neither of these are defined or are empty, perphup uses a compiled-in default, normally /etc/perp. When perphup finds the perpd(8) process, it sends it a SIGHUP signal. OPTIONS -h Help. Print a brief usage message to stderr and exit. -q Quiet.
