如何在Shell的递归目录中列出特定类型的文件? [英] How to list specific type of files in recursive directories in shell?

问题描述

我们如何找到特定类型的文件，即嵌套目录中存在的doc pdf文件.

How can we find specific type of files i.e. doc pdf files present in nested directories.

命令:

$ ls -R | grep .doc

但是，如果有文件名，例如alok.doc.txt，该命令也会显示该文件名，这显然不是我想要的.我应该改用什么命令?

but if there is a file name like alok.doc.txt the command will display that too which is obviously not what I want. What command should I use instead?

推荐答案

如果您更喜欢"ls"和"grep"，则可以使用grep命令中的正则表达式(以'$结尾'字符表示.doc必须在该行的末尾.这将排除"file.doc.txt"):

If you are more confortable with "ls" and "grep", you can do what you want using a regular expression in the grep command (the ending '$' character indicates that .doc must be at the end of the line. That will exclude "file.doc.txt"):

ls -R |grep "\.doc$"

有关在该人中使用带有正则表达式的grep的更多信息.
