使用实例

1. 删除空目录

   [fish@localhost ~]$ mkdir test
   [fish@localhost ~]$ tree
   .
   └── test

   1 directory, 0 files
   [fish@localhost ~]$ rmdir test/
   [fish@localhost ~]$ echo $?
   0

2. 删除父目录中的空目录

   [fish@localhost ~]$ mkdir -p a/b/c
   [fish@localhost ~]$ tree
   .
   └── a
   └── b
   └── c

   3 directories, 0 files
   [fish@localhost ~]$ rmdir -pv a/b/c/ # 显示删除过程
   rmdir: removing directory, ‘a/b/c/’
   rmdir: removing directory, ‘a/b’
   rmdir: removing directory, ‘a’
   [fish@localhost ~]$ ll
   total 0

3. 返回值测试

   [fish@localhost ~]$ mkdir -p a/{b/c,d} # 新建测试目录
   [fish@localhost ~]$ tree
   .
   └── a
   ├── b
   │ └── c
   └── d

   4 directories, 0 files
   [fish@localhost ~]$ rmdir -pv a/b/c/ # 显示删除次序
   rmdir: removing directory, ‘a/b/c/’
   rmdir: removing directory, ‘a/b’
   rmdir: removing directory, ‘a’
   rmdir: failed to remove directory ‘a’: Directory not empty
   [fish@localhost ~]$ echo $? # 执行mkdir a 时，因为存在a/d，故删除失败
   1
   [fish@localhost ~]$ tree
   .
   └── a
   └── d

   2 directories, 0 files
   [fish@localhost ~]$ rmdir -p a/d/ # 删除上次测试的所有文件
   [fish@localhost ~]$ mkdir -p a/{b/c,d} # 重新建立测试
   [fish@localhost ~]$ rmdir -pv --ignore-fail-on-non-empty a/b/c/ # 忽略失败，返回值为0
   rmdir: removing directory, ‘a/b/c/’
   rmdir: removing directory, ‘a/b’
   rmdir: removing directory, ‘a’
   [fish@localhost ~]$ echo $?
   0
   [fish@localhost ~]$ tree
   .
   └── a
   └── d

   2 directories, 0 files
