.Nd "introduction to system maintenance and operation commands"
|
|
.Sh DESCRIPTION
|
|
This section contains information related to system operation
|
|
and maintenance.
|
|
It describes commands used to create new file systems,
|
|
.Xr newfs 8 ,
|
|
verify the integrity of the file systems,
|
|
.Xr fsck 8 ,
|
|
control disk usage,
|
|
.Xr edquota 8 ,
|
|
maintain system backups,
|
|
.Xr dump 8 ,
|
|
and recover files when disks die an untimely death,
|
|
.Xr restore 8 .
|
|
The
|
|
.Xr format 8
|
|
manual
|
|
for the specific architecture the system is running on should be
|
|
consulted when formatting disks and tapes.
|
|
Network related services like
|
|
.Xr inetd 8
|
|
and
|
|
.Xr ftpd 8
|
|
are also described.
|
|
The
|
|
.Xr crash 8
|
|
manual page
|
|
should be consulted to understand how to interpret system
|
|
crash dumps.
|
|
.Pp
|
|
All commands set an exit status.
|
|
Its value may be tested
|
|
to see if the command completed normally.
|
|
Unless otherwise noted (rare), the value 0 signifies successful
|
|
completion of the command, while a value >0 indicates an error.
|
|
Some commands attempt to describe the nature of the failure by using
|
|
error codes defined in
|
|
.Xr sysexits 3 ,
|
|
or set the status to arbitrary values >0 (typically 1), but many
|
|
such values are not described in the manual.
