【问题描述】:
所以,我正在 macOS 10.13 上通过启动代理启动 Python (2.7) 脚本。该脚本运行,并在执行期间触发计算机重新启动。当计算机重新打开并登录时,启动代理会再次运行该脚本。该脚本读取日志,并执行 switch:case 以从中断处继续。
问题是,重启后python脚本无法执行一些shell命令。 ls -l 工作正常。但是,当我尝试运行不在 /bin 中的东西时,它似乎只是......跳过它。没有错误,它根本不这样做。
这是相关代码。我已经删除了大部分细节以及开关控制,因为我已经验证它们可以独立工作。
#!/usr/bin/python
import logging
import os
import subprocess
import time
#globals
path_to_plist = 'User/Me/Library/Preferences/PathTo.plist'
def spot_check():
#determine where we are in the test, verified it works
return loop_number
def func_that_checks_stuff():
results = subprocess.check_output(['System/Library/Path/To/tool','-toolarg'])
###process results
logging.info(results)
def restarts(power_on, power off):
#sets plist key values for the restart app
subprocess.Popen('defaults write {} plist_key1 {}'.format(path_to_plist, power_on), shell=True
subprocess.Popen('defaults write {} plist_key2 {}'.format(path_to_plist, power_off), shell=True
#run the restart app, which is a GUI application in /Applications
logging.info('Starting restart app')
subprocess.Popen('open -a RestartApp.app', shell=True)
time.sleep(power_on + 5)
def main():
###setup and config stuff, verified its working
#switch control stuff, verified its working
loop = spot_check()
if loop == 0:
#tool that shows text on the screen
subprocess.Popen('User/Me/Library/Scripts/Path/To/Text/tool -a -args', shell=True)
logging.info('I just ran that tool')
subprocess.check_output('ls -l', shell=True)
restarts(10, 0)
if loop == 1:
func_that_checks_stuff()
subprocess.Popen('User/Me/Library/Scripts/Path/To/Text/tool -a args', shell=True)
logging.info('Hey I ran that tool again, see?')
restarts(10, 0)
else:
func_that_checks_stuff()
subprocess.Popen('User/Me/Library/Scripts/Path/To/Text/tool -a args', shell=True)
print 'You finished!'
if __name__ == '__main__':
main()
所以,如果我使用启动代理启动它,它将很好地运行每个序列。
- 在第一个循环中(重新启动之前),一切正常。所有日志记录,所有工具,一切。
- 重新启动后,所有的日志记录工作,所以我知道它遵循开关控制。
func_that_checks_stuff()工作,并正确记录它的输出。ls -l' call shows me exactly what I should see. But,Path/To/Text/tooldoesn't run, and when I callrestarts()`,它永远不会打开应用程序。 - 没有产生错误,至少我能找到
我做错了什么?它与工具路径有关吗?
