Linux Process memory usage sorting command

The linux Process memory usage sorting command checks the linux server today. To view the usage of each process, use [qhkf @ 116 share ~]. $ Top pid user pr ni virt res shr s % CPU % mem time + COMMAND29613 build 15 0 158 m 7136 3720 S 2.0 0.1 0: 00. 27 svn29609 build 15 0 158 m 7132 3720 S 2.3 0: 00. 70 svn29601 qhkf 15 0 12868 1260 820 R 0.3 0.0 0: 00. 09 top29598 oracle 15 0 1935 m 15 m 13 m S 0.0 0: 00. 00 oracle29596 oracle 15 0 1936 m 27 m 24 m S 0.0 0: 00. 03 oracle29582 qhkf 15 0 102 m 3420 2252 S 0.0 0: 00. 04 vim29506 build 15 0 158 m 7252 3724 S 2.3 0: 03. 76 svn, but it is not sorted by memory. After checking, shift + f will show the sorted column Current Sort Field: N for window 1: DefSelect sort field via field letter, type any other key to return a: PID = Process Id shown due to screen width or your B: PPID = Parent Process Pid field order, the '<' and '> 'keys c: RUSER = Real user name will be unavailable until a field d: UID = User Id within viewable range is chosen. e: USER = User Name f: GROUP = Group Name Note2: g: TTY = Controlling Tty Field sorting uses internal values, h: PR = Priority not those in column display. thus, I: NI = Nice value the TTY & WCHAN fields will violate j: P = Last used cpu (SMP) strict ASCII collating sequence. k: % CPU = CPU usage (shame on you if WCHAN is chosen) l: TIME = CPU Time m: TIME + = CPU Time, hundredths * N: % MEM = Memory usage (RES) o: VIRT = Virtual Image (kb) p: SWAP = Swapped size (kb) q: RES = Resident size (kb) r: CODE = Code size (kb) s: DATA = Data + Stack size (kb) t: SHR = Shared Mem size (kb) u: nFLT = Page Fault count v: ndrc t = Dirty Pages count w: S = Process Status x: COMMAND = Command name/line y: WCHAN = Sleeping in Function z: Flags = Task Flags <sched. h> then you can select the sorting method you like. For example, select N to check whether the memory occupied by the processes is large, next we can analyze the pid user pr ni virt res shr s % CPU % mem time + COMMAND14101 oracle 15 0 1941 m 613 m 608 m S 0.0 7.7. 78 oracle14095 oracle 15 0 1987 m 521 m 477 m S 0.0. 58 oracle20477 oracle 15 0 1945 m 483 m 478 m S 0.0 0: 24. 79 oracle14522 oracle 15 0 1941 m 427 m 420 m S 0.0. 59 oracle14105 oracle 15 0 1941 m 268 m 262 m S 0.0 3.4. 04 oracle
