37 .Nd display system data structures
50 displays open file entry, swap space utilization,
51 terminal state, and vnode data structures.
57 option is implied, and only the
58 .Fl h , k , m , g , h , M
63 The following options are available:
64 .Bl -tag -width indent
66 Print devices out by major/minor instead of name.
68 Print sizes with human-readable scaling. BLOCKSIZE is ignored.
70 Print sizes in kilobytes, regardless of the setting of the
74 Print sizes in megabytes, regardless of the setting of the
78 Print sizes in gigabytes, regardless of the setting of the
82 Print the number of used and free slots in several system tables.
83 This is useful for checking to see how large system tables have become
84 if the system is under heavy load.
86 Print the open file table with these headings:
87 .Bl -tag -width indent
89 The core location of this table entry.
91 The type of object the file table entry points to.
93 Miscellaneous state variables encoded thus:
95 .Bl -tag -width indent -compact
105 exclusive lock present
107 signal pgrp when data ready
110 Number of processes that know this open file.
112 Number of messages outstanding for this file.
114 The location of the vnode table entry or socket structure for this file.
120 Print information about swap space usage on all the
121 swap areas compiled into the kernel.
122 The first column is the device name of the partition. The next column is
123 the total space available in the partition. The
125 column indicates the total blocks used so far; the
127 column indicates how much space is remaining on each partition.
130 reports the percentage of space used.
132 If more than one partition is configured into the system, totals for all
133 of the statistics will be reported in the final line of the report.
135 If you supply the option again, as in
137 the system will display a breakdown of the swap bitmap/radix-tree.
139 Print table for terminals
141 .Bl -tag -width indent
143 Number of characters in raw input queue.
145 Number of characters in canonicalized input queue.
147 Number of characters in output queue.
152 Physical device address.
154 Number of delimiters (newlines) in canonicalized input queue.
156 Calculated column position of terminal.
158 Miscellaneous state variables encoded thus:
160 .Bl -tag -width indent -compact
162 delay timeout in progress
164 waiting for open to complete
168 outq has been flushed during DMA
176 process is waiting for space in output queue
178 process is waiting for output to complete
180 open for exclusive use
182 output stopped (ixon flow control)
184 output stopped (carrier flow control)
186 output stopped (CTS flow control)
188 output stopped (DSR flow control)
204 next character is literal
206 retyping suspended input (PENDIN)
208 counting tab width, ignore FLUSHO
210 block mode input routine in use
217 Kernel address of the session structure.
219 Process group for which this is controlling terminal.
243 Extract values associated with the name list from the specified core
244 instead of the default
247 Extract the name list from the specified system instead of the default
251 .Bl -tag -width /dev/memxxx -compact
255 default source of tables
266 .%T UNIX Implementation
