DESCRIPTION +.Nm +displays statistics about the amount of free disk space on the specified +.Ar file_system +or on the file system of which +.Ar file +is a part. +By default, all sizes are reported in 512-byte block counts. +If neither a file or a +.Ar file_system +operand is specified, +statistics for all mounted file systems are displayed +(subject to the +.Fl l +and +.Fl t +options below). +.Pp +Note that the printed count of available blocks takes +.Va minfree +into account, and thus will be negative when the number of free blocks +on the filesystem is less than +.Va minfree . +.Pp +The following options are available: +.Bl -tag -width Ds +.It Fl a +Show all mount points, +including those that were mounted with the +.Dv MNT_IGNORE +flag. +.It Fl G +Display all the fields of the structure(s) returned by +.Xr statvfs 2 . +This option cannot be used with the +.Fl i +or +.Fl P +options, and it is modelled after the Solaris +.Fl g +option. +This option will override the +.Fl g , +.Fl h , +.Fl k , +and +.Fl m +options, as well as any setting of +.Ev BLOCKSIZE . +.It Fl g +The +.Fl g +option causes the numbers to be reported in gigabytes (1024*1024*1024 +bytes). +.It Fl h +"Human-readable" output. +Use unit suffixes: Byte, Kilobyte, Megabyte, +Gigabyte, Terabyte, Petabyte, Exabyte in order to reduce the number of +digits to four or less. +.It Fl i +Include statistics on the number of free inodes. +.It Fl k +By default, all sizes are reported in 512-byte block counts. +The +.Fl k +option causes the numbers to be reported in kilobytes (1024 bytes). +.It Fl l +Display statistics only about mounted file systems with the +.Dv MNT_LOCAL +flag set. +If a non-local file system is given as an argument, a +warning is issued and no information is given on that file system. +.It Fl m +The +.Fl m +option causes the numbers to be reported in megabytes (1024*1024 bytes). +.It Fl n +Print out the previously obtained statistics from the file systems. +This option should be used if it is possible that one or more +file systems are in a state such that they will not be able to provide +statistics without a long delay. +When this option is specified, +.Nm +will not request new statistics from the file systems, but will respond +with the possibly stale statistics that were previously obtained. +.It Fl P +Produce output in the following portable format: +.Pp +If both the +.Fl P +and +.Fl k +option are specified, the output will be preceded by the following header +line, formatted to match the data following it: +.Bd -literal +"Filesystem 1024-blocks Used Available Capacity Mounted on\en" +.Ed +.Pp +If the +.Fl P +option is specified without the +.Fl k +options, the output will be preceded by the following header line, +formatted to match the data following it: +.Bd -literal +"Filesystem \*[Lt]blksize\*[Gt]-blocks Used Available Capacity Mounted on\en" +.Ed +.Pp +The header line is followed by data formatted as follows: +.Bd -literal +"%s %d %d %d %d%% %s\en", \*[Lt]file system name\*[Gt], \*[Lt]total space\*[Gt], + \*[Lt]space used\*[Gt], \*[Lt]space free\*[Gt], \*[Lt]percentage used\*[Gt], + \*[Lt]file system root\*[Gt] +.Ed +.Pp +Note that the +.Fl i +option may not be specified with +.Fl P . +.It Fl t Ar type +Is used to indicate the actions should only be taken on +filesystems of the specified type. +More than one type may be specified in a comma-separated list. +The list of filesystem types can be prefixed with +.Dq no +to specify the filesystem types for which action should +.Em not +be taken. +If a file system is given on the command line that is not of +the specified type, a warning is issued and no information is given on +that file system. +.El +.Sh ENVIRONMENT +.Bl -tag -width BLOCKSIZE +.It Ev BLOCKSIZE +If the
