timeout命令默认运行在单独的进程组中,而终端的ctrl+c的SIGINT信号只发送给脚本,timeout命令接收不到。而脚本被timeout进程给阻塞了,要在timeout命令结束之后才会接收SIGINT信号。 想让timeout命令接收到终端的ctrl+c发送的SIGINT的信号,需要加上参数--foreground,这样timeout命令就会继承父进程的进程组。例子: timeout...

This Bash shell script executes a command with a time-out. Upon time-out expiration SIGTERM (15) is sent to the process. If the signal is blocked, then the subsequent SIGKILL (9) terminates it. This should work on any Linux distribution with Bash. Popular Posts: None Found Tuesday Februar...

Scripts(脚本语言)、Shell、Sh、Bash之间的关系Scripts脚本(Script),是一种特定的描述性语言,依据一定的格式编写的可执行文件。脚本语言与编译语言不同,用脚本语言写出的脚本文件可以直接作为可执行文件运行,无需像C或C++语言那样先编译再运行。脚本执行时,计算机会执行一连串的操作,脚本文件将不同的命令组合起来,并按照...
