-o format
              User-defined format.  format is a single argument in the form of a blank-separated or comma-separated list, which
              offers a way to specify individual output columns.  The recognized keywords are described in the STANDARD FORMAT
              SPECIFIERS section below.  Headers may be renamed (ps -o pid,ruser=RealUser -o comm=Command) as desired.  If all
              column headers are empty (ps -o pid= -o comm=) then the header line will not be output.  Column width will increase as
              needed for wide headers; this may be used to widen up columns such as WCHAN (ps -o pid,wchan=WIDE-WCHAN-COLUMN -o
              comm).  Explicit width control (ps opid,wchan:42,cmd) is offered too.  The behavior of ps -o pid=X,comm=Y varies with
              personality; output may be one column named "X,comm=Y" or two columns named "X" and "Y".  Use multiple -o options when
              in doubt.  Use the PS_FORMAT environment variable to specify a default as desired; DefSysV and DefBSD are macros that
              may be used to choose the default UNIX or BSD columns.
