       cls         CLS       scheduling   class   of   the   process.    (alias
                             policy, cls).  Field’s possible values are:

       cmd         CMD       see args.  (alias args, command).

       comm        COMMAND   command  name  (only  the  executable  name).  The
                             output in this column may contain spaces.   (alias
                             ucmd, ucomm).   See  also the args format keyword,
                             the -f option, and the c option.
                             When specified last, this column  will  extend  to
                             the  edge of the display.  If ps can not determine
                             display  width,  as  when  output  is   redirected
                             (piped) into a file or another command, the output
                             width  is  undefined  (it  may  be  80, unlimited,
                             determined by the TERM variable, and so on).   The
                             COLUMNS  environment variable or --cols option may
                             be used to exactly determine  the  width  in  this
                             case.   The  w or -w option may be also be used to
                             adjust width.

       command     COMMAND   See args.  (alias args, command).

       cp          CP        per-mill (tenths of a percent)  CPU  usage.   (see
                             %cpu).

                             (alias time).

       cputimes    TIME      cumulative CPU time in seconds (alias times).

       cuc         %CUC      The CPU utilization of a process,  including  dead
                             children,  in  an  extended "##.###" format.  (see
                             also %cpu, c, cp, cuu, pcpu).

       cuu         %CUU      The CPU utilization of a process  in  an  extended
                             "##.###"  format.   (see  also  %cpu,  c, cp, cuc,
                             pcpu).

       drs         DRS       data resident set  size,  the  amount  of  private
                             memory reserved by a process.  It is also known as
                             DATA. Such memory may not yet be mapped to rss but
                             will  always  be  included  included  in  the  vsz
                             amount.

       egid        EGID      effective group ID number  of  the  process  as  a
                             decimal integer.  (alias gid).

       egroup      EGROUP    effective  group  ID of the process.  This will be
                             the textual group ID, if it can  be  obtained  and
                             the    field   width   permits,   or   a   decimal
                             representation otherwise.  (alias group).

       eip         EIP       instruction pointer. As of kernel 4.9.xx  will  be
                             zeroed  out  unless  task is exiting or being core
                             dumped.

       esp         ESP       stack pointer. As of kernel 4.9.xx will be  zeroed
                             out unless task is exiting or being core dumped.

       etime       ELAPSED   elapsed time since the process was started, in the

Title: ps - Standard Format Specifiers (Continued)

Summary

This section describes further standard format specifiers for the ps command, explaining how various keywords control output format and sorting. Keywords described include command, cp, cputime/cputimes, cuc/cuu, drs, egid/egroup, eip/esp, etime/etimes, with explanations of the information they display, their formatting, and aliases where applicable. It covers CPU usage in various forms, memory size, user and group IDs, instruction and stack pointers, and elapsed time since process start.
