用ls -l 可以看到有一個文檔的硬鏈接數:
[root@localhost tmp]# ls -li
total 104
229415 drwxr-xr-x 2 root root 4096 Dec 11 21:15 etc
39757 -rw-r--r-- 2 root root 1602 Oct 30 14:56 hl_passwd
用一下語句可以查看一個文件有哪些硬鏈接
[root@localhost tmp]# find / -inum 39757
find: /proc/6266/task/6266/fd/4: No such file or directory
/etc/passwd
/tmp/hl_passwd
但是注意由於硬鏈接是不能跨文件系統的,所以
Add the `-xdev' option if you are starting the
search at a directory that has other filesystems mounted on it,
