'find'（命令）找不到-wholename [英] 'find' (command) finds nothing with -wholename

问题描述

此命令为什么起作用：

/home/user1/tmp $ find ./../.. -wholename '.*/tmp/file.c' -exec echo '{}' \;
./../../user2/tmp/file.c
/home/user1/tmp $

此命令不起作用？ （什么也没找到）

And this command does not work? (finds nothing)

/home/user1/tmp $ find /home -wholename '.*/tmp/file.c' -exec echo '{}' \;
/home/user1/tmp $

推荐答案

第一个命令生成以 ./../ .. 开头的文件名。因此，全名模式将匹配，因为它们以开头。。

The first command generates file names starting with ./../... Thus the wholename pattern will match because they start with ..

第二条命令生成以<$ c开头的文件名$ c> / home 。但是，全名模式仍在寻找以开头的路径。在这种情况下将不匹配任何文件。

The second command generates filenames starting with /home. However, the wholename pattern is still looking for paths starting with . which will not match any file in this case.

请注意，模式不是不是正则表达式。如果您期望它们，请改用 -regex 选项。

Note that patterns are not regular expressions. If you were expecting them, look at the -regex option instead.
