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
