我在日期范围内运行了一组m/r报告，现在有一系列目录，如：
/user/michael/output/TrueListingSellThroughFromLeafCategory/{20120101,20120102,20120103,20120104,20120105,20120106,20120107}
/user/michael/output/TrueListingSellThroughFromLeafCategory/{20120108,20120109,20120110,20120111,20120112,20120113,20120114}
/user/michael/output/TrueListingSellThroughFromLeafCategory/{20120115,20120116,20120117,20120118,20120119,20120120,20120121}我很难浏览这些目录。如果我试着 ls 其中之一，它将日期作为一个列表，并为每个日期查找不同的目录。如果我转义大括号，我会得到一个没有这样的文件或目录错误。如果我用%7b和%7d替换大括号，情况就类似了。
如果我通配符的水平，然后我可以浏览较低的：
/user/michael/output/TrueListingSellThroughFromLeafCategory/*但如果能一次找回一个就好了！我该怎么做？

看起来你应该可以用regex操作符来修复它
?```hadoop fs -ls /user/michael/output/TrueListingSellThroughFromLeafCategory/?20120101,20120102,20120103,20120104,20120105,20120106,20120107?
