75 If directory names are given, as output by default,
76 then per file system information is displayed.
80 Request automounter to flush the internal caches.
84 By default the local host is used.
87 cluster, the root server is queried by default, since
88 that is the system on which the automounter is normally run.
93 For security reasons, this must be the same log file which
96 This option is therefore only useful to
99 open file handle on the log file, so that it can be rotated and compressed via
102 Request the automounter to provide a list of mounted file systems,
103 including the number of references to each file system and any error
104 which occurred while mounting.
106 Return the process ID of the remote or locally running
108 Useful when you need to send a signal to the local
110 process, and would rather not have to search through the process table.

116 Request the automounter to provide system-wide mount statistics.
118 Request the automounter to unmount the named file systems
119 instead of providing information about them.
120 Unmounts are requested,
122 They merely cause the mounted file system to timeout,
123 which will be picked up by
125 main scheduler thus causing the normal timeout action to be taken.
