manページを見ると、ps実際に知りたかったすべての内容が出力に表示されることがわかります。VSZ virtual memory size of the process in KiB (1024-byte units). Device mappings are currently excluded; this is subject to change. (alias vsize). RSS resident set size, the non-swapped physical memory that a task has used (in kiloBytes). (alias rssize, rsz).コマンドと一緒に
--sortコマンドオプションをps使用して並べ替えることができます。たとえば、vszrssheadps aux --sort -rss | headまた
ps、表示する内容と方法を正確に指定してから、出力をawk人間が読みやすい形式にパイプすることもできます。ps -eo pid,vsz,rss,comm --sort -rss,-vsz | head \ | awk 'NR>1 {$2=int($2/1024)"M";$3=int($3/1024)"M"}{ print;}' \ | column -t
