排序需要使用到 sort
sort
-r, --reverse: 降序，不指定默认是升序
-h, ---human-numeric-sort: 以人类可读方式展示 (如: 2K 1G)
-M, --month-sort: 可比较月份，(如 'JAN' < ... < 'DEC')
-k, --key=开始列号[,结束列号]: 指定按第几个字段排序，不指定默认是按整行排序，默认分隔符是空格
若要指定分隔符如 ";", 则需要使用 -t
-t, --field-separator=分隔符: 配合 -k 使用，指定分隔符, 不指定默认是空格
将 ps -ef 内容进行排序输出
ps -ef | sort -k3,3 -hr 默认分隔符为空格，按第3个字段降序排序
