ps、grep、awk、xargs、kill
Linux ps英文全拼process status命令用于显示当前进程的状态类似于 windows 的任务管理器。Linux grep 命令用于查找文件里符合条件的字符串。awk 是一种处理文本文件的语言是一个强大的文本分析工具。xargs英文全拼extended arguments是给命令传递参数的一个过滤器也是组合多个命令的一个工具。Linux kill 命令用于删除执行中的程序或工作。 -v, --invert-match select non-matching lines用例列出所有进程的详细信息查找名称带有指定字符串的进程过滤掉grep进程提取出pid传递给kill从而批量杀死进程。# 查找名称带有python的进程
$ ps -ef | grep python | grep -v grep

......# 查找名称带有python的进程过滤掉grep进程提取出pid传递给kill
# 请视自己的情况来执行
$ ps -ef | grep python | grep -v grep | awk {print $2} | xargs kill
# 批量杀死进程后再执行一遍会显示kill的帮助信息因为没有参数传递给kill
$ ps -ef | grep python | grep -v grep | awk {print $2} | xargs kill
Usage:kill [options] pid [...]Options:pid [...] send signal to every pid listed-signal, -s, --signal signalspecify the signal to be sent-l, --list[signal] list all signal names, or convert one to a name-L, --table list all signal names in a nice table-h, --help display this help and exit-V, --version output version information and exitFor more details see kill(1).lsblk
Linux中的lsblk命令用于列出所有可用块设备的信息而且还能显示他们之间的依赖关系但是它不会列出RAM盘的信息。块设备有硬盘闪存盘CD-ROM等等。用例查看哪些硬盘是固态硬盘。$ lsblk -o NAME,MOUNTPOINT,SIZE,ROTA
