2 BSD options, which may be grouped and must not be used with a dash.
If you want a repetitive update of the selection and the displayed information, use top instead.
If the user named “x” does not exist, this ps may interpret the command as “ps aux” instead and print a warning.
BSD options may be grouped and must not be used with a dash.
BSD options, which may be grouped and must not be used with a dash.
The POSIX and UNIX standards require that “ps-aux” print all processes owned by a user named “x”, as well as printing all processes that would be selected by the-a option.
The use of BSD-style options will also change the process selection to include processes on other terminals that are owned by you; alternately, this may be described as setting the selection to be the set of all processes filtered to exclude processes owned by other users or not on a terminal.
Terminals can be specified in several forms: /dev/ttyS1, ttyS1, S1.
The “-g” option can select by session leader OR by group name.
-]key ] Choose a multi-letter key from the STANDARD FORMAT SPECIFIERS section.
Select all processes except session leaders.
Lift the BSD-style “only yourself” restriction, which is imposed upon the set of all processes when some BSD-style options are used or when the ps personality setting is BSD-like.
An alternate description is that this option causes ps to list all processes with a terminal , or to list all processes when used together with the x option.
Select all processes except session leaders and processes not associated with a terminal.
This selects the processes with a parent process ID in pidlist.
Select by effective user ID or name.
-]k2 ] Order the process listing according to the multilevel sort specified by the sequence of short keys from SORT KEYS, k1, k2,… The.+’ is quite optional, merely re-iterating the default direction on a key.
You can override this with the PS_FORMAT environment variable.
Add a column of security data.
Select by real group ID or name.
CPU usage is currently expressed as the percentage of time spent running during the entire lifetime of a process.
Sum up some information, such as CPU usage, from dead child processes into their parent.
An alternate description is that this option causes ps to list all processes owned by you , or to list all processes when used together with the a option.
There are some synonymous options, which are functionally identical, due to the many standards and ps implementations that this ps is compatible with.
The PS_PERSONALITY environment variable provides more detailed control of ps behavior.
It is normally implied by the a flag, and is only useful when operating in the sunos4 personality.
Processes marked are dead processes that remain because their parent has not destroyed them properly.
