machineenv 1 user commands nosh machineenv set the "machine" environment variables from the dynamic values machineenv next-prog machineenv is a chain-loading utility that sets environment variables and then chain loads to next-prog with the execvp3 function. next-prog may contain its own command line options, which machineenv will ignore. The following environment variables are set: MACHINEID Set to the human-readable hexadecimal non-punctuated form of the machine ID, for details on which (and some caveats as to mis-use) see machine-id7. HOSTNAME Set to the dynamic "host" name, as initialized by set-dynamic-hostname1 (for example) and obtained by the gethostname2 function. DOMAINNAME Set to the dynamic "NIS domain" name, as obtained by the getdomainname2 function. This is not the "DNS domain" name, conventionally found in a LOCALDOMAIN environment variable. As of version 1.34 this program no longer employs the GNU C library nor the BSD C library for environment variable handling. The previously documented workaround for those libraries' having memory leaks in their setenv3 and clearenv3 functions, is therefore no longer necessary. userenv-fromenv1 setenv1 envuidgid1 clearenv1 Jonathan de Boyne Pollard
