请问ps命令查出来的rss/vsz/size分别是何含义呢？

rss        RSS      resident set size, the non-swapped physical memory that a task has used (in kiloBytes). (alias rssize, rsz).


vsz        VSZ      virtual memory size of the process in KiB (1024-byte units). Device mappings are currently excluded; this is subject
                    to change. (alias vsize).


size       SZ       approximate amount of swap space that would be required if the process were to dirty all writable pages and then be
                    swapped out. This number is very rough!


sz         SZ       size in physical pages of the core image of the process. This includes text, data, and stack space. Device mappings
                    are currently excluded; this is subject to change. See vsz and rss.
