vmstathas default output which is similar in nature and takes many options that give extremely detailed information, egvmstat -mswapinfowould cover the swap parttop -d1causes top to print one screen and exit, and the banner is very similar tofree. Usetop -d1 | head -n 7to see only the banner
vmstat具有本质上相似的默认输出，并采用许多提供极其详细信息的选项，例如vmstat -mswapinfo将涵盖交换部分top -d1导致 top 打印一屏退出，banner 与free. 用于top -d1 | head -n 7仅查看横幅

vmstat -sgives some more human-readable or script-parseable information, including listing the page size. Otherwise, it gives output in numbef of pages. With no options, vmstatgives a brief summary.
vmstat -s提供了一些更易读或脚本可解析的信息，包括列出页面大小。否则，它会以 numbef 的页数给出输出。没有选项，vmstat给出一个简短的总结。
The vmstatcommand also exists on NetBSD.
该vmstat命令也存在于 NetBSD 上。
