我的macbook中有一个cronjob（每10分钟截取一次屏幕截图）和mac osx El Capitan，它遵循以下命令：
*/10 * * * * cd /Users/userx/Pictures/memes && ./shared.sh
shared.sh脚本包含以下内容：
#!/bin/bash
_now=$(date +"%m_%d_%Y_%H_%M_%S")
screencapture -x $_now.png
但是当系统执行cronjob时，我收到了这个错误：
./shared.sh: line 3: screencapture: command not found
但如果我直接在终端中运行shared.sh文件，则所有操作都正确执行。
任何想法？我们可以从cronjobs运行mac osx命令吗？

位于/ usr / sbin中，但cron作业的默认PATH仅为screencapture，因此找不到它。有几种方法可以解决这个问题：
/usr/bin:/bin）。/usr/sbin/screencapture -x $_now.png（即screencapture）之前在脚本中设置PATH。
