You can combine MACHINE and LOGNAME entries into a single entry when the common options are the same. For example, the two sets of entries that follow share the same –REQUEST, –READ, and –WRITE options:
MACHINE=eagle:owl:hawk REQUEST=yes \ READ=/ WRITE=/
LOGNAME=uupz REQUEST=yes SENDFILES=yes \ READ=/ WRITE=/
You can merge these entries, as shown:
MACHINE=eagle:owl:hawk REQUEST=yes \ logname=uucpz SENDFILES-yes \ READ=/ WRITE=/
Combining MACHINE and LOGNAME entries makes the Permissions file more manageable and efficient.
