44 utility displays detailed information about the processes identified by the
48 flag is used, all processes.
49 It can also display information extracted from a process core file, if
50 the core file is specified as the argument.
52 By default, basic process statistics are printed; one of the following
53 options may be specified in order to select more detailed process information
55 .Bl -tag -width indent
59 in a selection of different human and machine readable formats.
62 for details on command line arguments.
64 Display binary information for the process.
66 Display command line arguments for the process.
68 Display environment variables for the process.
70 Display file descriptor information for the process.
72 Display signal pending and disposition information for the process.
74 Display signal pending and blocked information for the process's threads.
76 Display the stacks of kernel threads in the process, excluding stacks of
77 threads currently running on a CPU and threads with stacks swapped to disk.
78 If the flag is repeated, function offsets as well as function names are
81 Display resource limits for the process.

89 Display the cpuset information for the thread.
91 Display thread information for the process.
93 Display virtual memory mappings for the process.
95 Display ELF auxiliary vector for the process.
98 All options generate output in the format of a table, the first field of
99 which is the process ID to which the row of information corresponds.
102 flag may be used to suppress table headers.
106 flag may be used to specify a wait interval at which to repeat the printing
107 of the requested process information.
110 flag is not specified, the output will not repeat.
114 flag requests the printing of additional capability information in the file
119 flag may be used to request per-thread statistics rather than per-process
120 statistics for some options.
121 For those options, the second field in the table will list the thread ID
122 to which the row of information corresponds.
125 flag is implied for the
129 Information for VM, file descriptor, and cpuset options is available
130 only to the owner of a process or the superuser.
131 A cpuset value displayed as -1 means that the information is either invalid
