尝试kill与Java相关的非常进程。有没有办法使用管道？我试过了

ps -e|grep "java"|kill

and

和

ps -e|grep "java"|xargs kill

Neither works.

两者都不起作用。

Answer 1

pgrepis the right tool for grepping processes:

pgrep是 grepping 进程的正确工具：

kill $(pgrep -f java)

the -fflag in pgrepis for matching against the full command line used to execute a process.

pgrep 中的-f标志用于匹配用于执行进程的完整命令行。

There is, but this is easier (presuming your system has killall):

有，但这更容易（假设您的系统有killall）：

killall java

Answer 3
