OSX bash "sleep"
提问by Chuck
I'm trying to suspend or "sleep" a specific line in a bash script running in OSX. The script runs at startup before login. I'm not seeing the results I'm expecting. In other words no matter what time I specify after "sleep" the script still moves right along with no delay what so ever. However when I run the script after login, the "sleep" command seems to work just fine.
我正在尝试暂停或“休眠”OSX 中运行的 bash 脚本中的特定行。该脚本在登录前启动时运行。我没有看到我期待的结果。换句话说，无论我在“睡眠”后指定什么时间，脚本仍然会立即移动，没有任何延迟。但是，当我在登录后运行脚本时，“sleep”命令似乎工作得很好。
Is it possible that the command file "sleep" isn't in the path before login or before my script runs? Would it help if I placed the path to sleep before the command? If so where does "sleep" live?
在登录之前或我的脚本运行之前，命令文件“sleep”是否可能不在路径中？如果我在命令之前放置睡眠路径会有帮助吗？如果是这样，“睡眠”住在哪里？
Is there another approach or alternative command I could try?
我可以尝试另一种方法或替代命令吗？
Thanks
谢谢
#!/bin/bash
#Create the bin directory
sudo mkdir /usr/local/bin
sleep 10
#Copy the files to the Hard Drive
sudo cp /Volumes/NO\ NAME/adbind.bash /usr/local/bin/adbind.bash
sudo cp /Volumes/NO\ NAME/com.sjusd.adbind.plist /Library/LaunchDaemons/com.sjusd.adbind.plist
#Fix permissions
sudo chown root:wheel /usr/local/bin
sudo chmod 755 /usr/local/bin
sudo chown root:wheel /Library/LaunchDaemons/com.sjusd.adbind.plist
sudo chmod 755 /Library/LaunchDaemons/com.sjusd.adbind.plist
exit 0

This might be a little late, but it seems that sleep on OS X doesn't work with quantifiers (m,h, ...). Official Apple documentation
这可能有点晚了，但似乎 OS X 上的 sleep 不适用于量词 (m,h, ...)。苹果官方文档
So "sleep 5m" is the same as "sleep 5". If you want 5 minutes, you have to use "sleep 300"
所以“sleep 5m”和“sleep 5”是一样的。如果你想要5分钟，你必须使用“sleep 300”

If you run which sleep, you can get the path to 'sleep' on your system. I get /bin/sleep.
如果您运行which sleep，您可以获得系统上“睡眠”的路径。我明白了/bin/sleep。
At this point, you have a couple of options:
此时，您有几个选择：
you can specify the path to sleepwhen you call it
您可以指定sleep调用它时的路径
#!/bin/bash
# script before sleep ...
/bin/sleep
# ... after sleep
or you can add the path to your $PATHvariable within your script before you call it.
或者您可以$PATH在调用之前在脚本中添加变量的路径。
#!/bin/bash
PATH="$PATH:/bin"
# script before sleep ...
sleep
# ... after sleep
