##  PCP ENVIRONMENT  top

    
    
           Environment variables with the prefix **PCP_** are used to
           parameterize the file and directory names used by PCP.  On each
           installation, the file _/etc/pcp.conf_ contains the local values
           for these variables.  The **$PCP_CONF** variable may be used to
           specify an alternative configuration file, as described in
           [pcp.conf(5)](../man5/pcp.conf.5.html).
