| usage: ps [-AadefLlnwZ] [-gG GROUP,] [-k FIELD,] [-o FIELD,] [-p PID,] [-t TTY,] [-uU USER,]
List processes.
Which processes to show (selections may be comma separated lists):
-A All processes
-a Processes with terminals that aren't session leaders
-d All processes that aren't session leaders
-e Same as -A
-g Belonging to GROUPs
-G Belonging to real GROUPs (before sgid)
-p PIDs (--pid)
-P Parent PIDs (--ppid)
-s In session IDs
-t Attached to selected TTYs
-T Show threads
-u Owned by USERs
-U Owned by real USERs (before suid)
Output modifiers:
-k Sort FIELDs in +increasing or -decreasting order (--sort)
-M Measure field widths (expanding as necessary)
-n Show numeric USER and GROUP
-w Wide output (don't truncate fields)
Which FIELDs to show. (Default = -o PID,TTY,TIME,CMD)
-f Full listing (-o USER:12=UID,PID,PPID,C,STIME,TTY,TIME,ARGS=CMD)
-l Long listing (-o F,S,UID,PID,PPID,C,PRI,NI,ADDR,SZ,WCHAN,TTY,TIME,CMD)
-o Output FIELDs instead of defaults, each with optional :size and =title
-O Add FIELDS to defaults
-Z Include LABEL
Command line -o fields:
ARGS CMDLINE minus initial path CMD Command (thread) name (stat[2])
CMDLINE Command line (argv[]) COMM Command filename (/proc/$PID/exe)
COMMAND Command file (/proc/$PID/exe) NAME Process name (argv[0] of $PID)
Process attribute -o FIELDs:
ADDR Instruction pointer BIT Is this process 32 or 64 bits
CPU Which processor running on ETIME Elapsed time since PID start
F Flags (1=FORKNOEXEC 4=SUPERPRIV) GID Group id
GROUP Group name LABEL Security label
MAJFL Major page faults MINFL Minor page faults
NI Niceness (lower is faster)
PCPU Percentage of CPU time used PCY Android scheduling policy
PGID Process Group ID
PID Process ID PPID Parent Process ID
PRI Priority (higher is faster) PSR Processor last executed on
RGID Real (before sgid) group ID RGROUP Real (before sgid) group name
RSS Resident Set Size (pages in use) RTPRIO Realtime priority
RUID Real (before suid) user ID RUSER Real (before suid) user name
S Process state:
R (running) S (sleeping) D (device I/O) T (stopped) t (traced)
Z (zombie) X (deader) x (dead) K (wakekill) W (waking)
SCHED Scheduling policy (0=other, 1=fifo, 2=rr, 3=batch, 4=iso, 5=idle)
STAT Process state (S) plus:
< high priority N low priority L locked memory
s session leader + foreground l multithreaded
STIME Start time of process in hh:mm (size :19 shows yyyy-mm-dd hh:mm:ss)
SZ Memory Size (4k pages needed to completely swap out process)
TCNT Thread count TID Thread ID
TIME CPU time consumed TTY Controlling terminal
UID User id USER User name
VSZ Virtual memory size (1k units) %VSZ VSZ as % of physical memory
WCHAN What are we waiting in kernel for
