如何重命名文件以排除日期时间戳？

Question

我想要一个正则表达式来重命名我的文件。Microsoft Windows 更改了我的文件名，我想从文件名中删除带括号的日期时间子字符串。

以下是一些示例文件名：

icon-culture (2015_09_04 06_58_44 UTC).png
icon-disk (2015_09_04 06_58_44 UTC).png
icon-download (2015_09_04 06_58_44 UTC).png
icon-drop (2015_09_04 06_58_44 UTC).png
icon-file (2015_09_04 06_58_44 UTC).png
icon-film (2015_09_04 06_58_44 UTC).png
icon-flag (2015_09_04 06_58_44 UTC).png
icon-folder (2015_09_04 06_58_44 UTC).png
icon-garbage (2015_09_04 06_58_44 UTC).png
icon-graph (2015_09_04 06_58_44 UTC).png
icon-heart (2015_09_04 06_58_44 UTC).png
icon-help (2015_09_04 06_58_44 UTC).png
icon-lock (2015_09_04 06_58_44 UTC).png
icon-map (2015_09_04 06_58_44 UTC).png
icon-media (2015_09_04 06_58_44 UTC).png
icon-money (2015_09_04 06_58_44 UTC).png
icon-monitor (2015_09_04 06_58_44 UTC).png
icon-notes (2015_09_04 06_58_44 UTC).png
icon-openmail (2015_09_04 06_58_44 UTC).png
icon-phone (2015_09_04 06_58_44 UTC).png
icon-photo (2015_09_04 06_58_44 UTC).png

重命名后我想要的文件名是：

icon-culture.png
icon-disk.png
icon-download.png
icon-drop.png
icon-file.png
icon-film.png
icon-flag.png
icon-folder.png
icon-garbage.png
icon-graph.png
icon-heart.png
icon-help.png
icon-lock.png
icon-map.png
icon-media.png
icon-money.png
icon-monitor.png
icon-notes.png
icon-openmail.png
icon-phone.png
icon-photo.png

我发现的教程对我来说效果不佳，因为有一些特殊字符和数字。

s/ \(.*?\)//是一个简单的，如果广泛的表达式，匹配一个空格后跟括号括起来的东西。您可以选择更精确的表达式，例如：

• s/ \(.*?\)\.png$/.png/- 与前一个类似，但仅在后跟.png和文件名结尾时匹配，或
• s/ \(\d{4}(_\d\d){2} \d\d(_\d\d){2} UTC\)\.png/.png/- 匹配这些文件中显示的日期模式，并遵循.png.

该-n选项用于测试命令。如果您对结果感到满意，请在没有它​​的情况下运行。
