[英]Bash script with kill command
If I try to kill a process in bash script it returns me the following error: : arguments must be process or job IDs如果我尝试终止 bash 脚本中的进程,它会返回以下错误::arguments must be process or job IDs
#!/bin/bash
PID=`cat /var/www/html/pid.txt`
kill -SIGKILL $PID
It acts like kill
is getting a non-numerical value.它的行为就像
kill
正在获得一个非数值。 If the process ID just doesn't exist, you get a different error (no such process).如果进程 ID 不存在,则会出现不同的错误(没有这样的进程)。
I would look at the text file itself.我会看一下文本文件本身。 Make sure there aren't any special characters and that the PID is purely numerical.
确保没有任何特殊字符并且 PID 是纯数字的。
Try something like this:尝试这样的事情:
kill -9 $(cat /var/www/html/pid.txt | sed -e 's/[^0-9]\+//g')
If the process just doesn't exist, I'd expect an error like this:如果该过程不存在,我预计会出现这样的错误:
bash: kill: (2100) - No such process
