Question

我正在制作一个简单的bash编码我不知道如何实现这一点，这对你们来说可能很容易请帮忙。

我在file.sh上有一个简单的程序

#!/bin/bash

./program

这个./program是C程序的编译版本，我使用GCC我试图在bash脚本中使用它来执行这个程序几秒钟然后在x间隔时间之后终止并再次重启。

我希望你明白我的观点？

示例：运行file.sh 10秒钟，我将显示./program C程序的结果，然后在10秒后重新启动。

Answer 1

如果我理解正确，答案是sleep和timout的组合：

while :; do
    timout 10s ./program
    # display some results
    sleep 10
done

Answer 2

您可以使用$ pip install --verbose ./foo Processing ./foo Running setup.py (path:/private/var/folders/4d/bt0_xfx56bjfmmt2bv3r5_qh0000gn/T/pip-ti0o0gtu-build/setup.py) egg_info for package from file:///Users/pradyunsg/.venvwrap/venvs/t mp-c0ebb35987c76ad/foo Running command python setup.py egg_info running egg_info creating pip-egg-info/foo.egg-info writing pip-egg-info/foo.egg-info/PKG-INFO writing dependency_links to pip-egg-info/foo.egg-info/dependency_links.txt writing top-level names to pip-egg-info/foo.egg-info/top_level.txt writing manifest file 'pip-egg-info/foo.egg-info/SOURCES.txt' reading manifest file 'pip-egg-info/foo.egg-info/SOURCES.txt' writing manifest file 'pip-egg-info/foo.egg-info/SOURCES.txt' Source in /private/var/folders/4d/bt0_xfx56bjfmmt2bv3r5_qh0000gn/T/pip-ti0o0gtu-build has version 0.0.0, which satisfies requirement foo==0.0.0 from file:///Users/pradyunsg/.ve nvwrap/venvs/tmp-c0ebb35987c76ad/foo Could not parse version from link: file:///Users/pradyunsg/.venvwrap/venvs/tmp-c0ebb35987c76ad/foo Installing collected packages: foo Running setup.py install for foo ...

要连续运行，直到您关闭终端：

sh

在X时运行Bash命令并在X时间终止
