为什么我的绑定挂载上的 find 不起作用

  • 772

我正在运行 lubuntu 20.04。

在 /etc/fstab 中，我挂载了我的 Debian-home 文件系统，并从该文件系统中绑定了一个文件夹。

cat /etc/fstab 
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#
# <file system>             <mount point>  <type>  <options>  <dump>  <pass>
UUID=a19641aa-75ea-4815-b7c3-ce4c0a3cd0c9 /              ext4    defaults,discard 0 1
UUID=3bbf1ad8-b0d0-464e-a73b-9337e16d95d0 /home          ext4    defaults   0 2
UUID=927f38a0-c962-47de-9361-f1730032704e swap           swap    defaults   0 2
# Debian-home einbinden  # my debian $HOME filesystem
UUID=1ebf0f02-cdd8-44d9-80f9-7078de79e191  /media/debian-home-partition  ext4 user,auto    0       2
# einzelne Ordner einbinden von debian-home # folder with Videos
/media/debian-home-partition/alex/jd2  /home/alex/jd2   none  bind,defaults                 0       0

tmpfs                                     /tmp           tmpfs   defaults,noatime,mode=1777 0 0

debian 和 ubuntu 中的用户名和 (id/gid) 相同。我可以将 ubuntu $HOME 中的 mv 或 cp 文件绑定到文件夹。

但不知何故 find 不起作用。

find jd2/downloads/ -name Xemnas

没有什么。

但

ls -al jd2/downloads/ | grep -i xemnas

尝试一点调试

我的绑定安装不正确吗？还是我通过 find 命令监督了某些事情？

    命令

    find <path> -name xemnas

    只会匹配名称完全正确的文件xemnas- 等同于您ls ... | grep -i xemnas需要的命令

    find <path> -iname '*xemnas*'

    其中*s 是匹配零个或多个前导/尾随字符的全局通配符，-iname并使匹配不区分大小写。对于您的特定情况，您还可以使用使最初的 X 不区分大小写-name '*[Xx]emnas*'
