Bash Script on a Mac creates a info popup
提问by Arcath
Is there a way in bash on a mac to draw a pretty info box that displays a simple message like "please save all files to /Users/......"
有没有办法在 Mac 上的 bash 中绘制一个漂亮的信息框，显示一条简单的消息，例如“请将所有文件保存到 /Users/......”

You can run fragments of applescript from you bash scripts. A simple popup would look like this:
您可以从 bash 脚本运行 applescript 的片段。一个简单的弹出窗口如下所示：
#!/bin/bash
/usr/bin/osascript <<-EOF
tell application "System Events"
activate
display dialog "Hello world"
end tell
EOF
This will feed the applescript between the EOF tags to osascript and execute it
(resulting in a Hello World popup).
这会将 EOF 标记之间的 Applescript 提供给 osascript 并执行它
（导致 Hello World 弹出窗口）。

An alternative to osascript "System Events" would be to install cocoaDialog.
osascript“系统事件”的替代方法是安装cocoaDialog。
cocoaDialog has the disadvantage that it must be installed, but it seems to be much more flexible than the "System Events".
cocoaDialog 的缺点是必须安装，但它似乎比“系统事件”灵活得多。

(osascript was littering my terminal with error messages (at least under Lion) and with return values, it didn't let me do popups with timeouts, and seemed to require specific quoting which made it hard to use variables in the texts.)
（osascript 用错误消息（至少在 Lion 下）和返回值散布我的终端，它不允许我使用超时弹出窗口，并且似乎需要特定的引用，这使得很难在文本中使用变量。）
