用WatchPaths键启动Launchd.plist:如何设置最小间隔? [英] Launchd.plist with WatchPaths key: How to set a minimum interval?

问题描述

如何使用WatchPath键为launchd.plist脚本设置最小间隔?

How would one set a minimum interval for a launchd.plist script with a WatchPath key?

例如，我希望每次新文件出现在目录中时都运行一个脚本，但是我希望它最多每小时仅运行一次.

For example, I want to run a script every time new files appear in a directory, but I would like it to only run once an hour at maximum.

launchd.plist可能看起来像这样:

The launchd.plist might look something like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>org.me.pytag</string>
  <key>ProgramArguments</key>
  <array>
    <string>/Users/me/bin/pytag.py</string>
  </array>
  <key>WatchPaths</key>
  <array>
    <string>/Volumes/Data/Media/Video/Processing/Converted</string>
  </array>
  <key>StandardOutPath</key>
  <string>/dev/null</string>
</dict>
</plist>

推荐答案

添加此属性.请注意，整数以秒为单位.

Add this property. Note that the integer is in seconds.

<key>ThrottleInterval</key>
  <integer>3600</integer>
