方法如下：
用ls -l 可以看到有一個(gè)文檔的硬鏈接數(shù)：

[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(yǔ)句可以查看一個(gè)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

但是注意由于硬鏈接是不能跨文件系統(tǒng)的，所以

Add the `-xdev' option if you are starting the

search at a directory that has other filesystems mounted on it
