[英]How can I kill all child processes when exiting from my shell script?
I've got a C shell script that runs a program. 我有一个运行程序的C shell脚本。 That program spawns off a child.
该程序产生了一个孩子。 When I send a SIGINT to my shell script via ctrl-C, the shell script exits as well as the process that it spawned I think.
当我通过ctrl-C将SIGINT发送到我的shell脚本时,该shell脚本以及它产生的进程都会退出。 However, the last process remains.
但是,最后一个过程仍然存在。 How can I instruct C shell to kill all child processes before it exits then?
我如何指示C Shell在退出子进程之前将其杀死?
How about creating a signal trap for SIGINT? 如何为SIGINT创建信号陷阱? See the Interrupt Handling section here :
请参见此处的“中断处理”部分 :
#!/bin/csh
# Setup sigint handler
onintr close
# start a background process
sleep 1000&
setenv pid $!
while (1 == 1)
echo Program is running
sleep 2
end
close:
echo End of program. Kill $pid
kill $pid
