使用linux命令获取特定进程

Question

我有这个命令：

ps -C java -o pid=,%mem=,vsz=,%cpu=,command=

产生以下输出：

我正在尝试获取特定的 Java 进程，但我获取了所有 Java 进程，而我正在尝试仅获取特定的进程。我怎样才能改变命令来做到这一点？

Answer 1

一旦你有了 pid (9067)

ps -p 9067 -o pid=,%mem=,vsz=,%cpu=,command=

编辑因为我只是从问题中复制命令我没有注意到有很多=，最后只能有一个=，它是删除标题

ps -p 9067 -o pid,%mem,vsz,%cpu,command
ps -p 9067 -o pid,%mem,vsz,%cpu,command=

man ps了解更多信息

Answer 2

快速方法 - 使用 grep：

ps -C java -o pid=,%mem=,vsz=,%cpu=,command= |grep S‌​NAPSHOT/conf/engine_‌​logback.xml
