How do I see if a file has a soft link or a hard-link file under Linux?

problem 1 : I created a hard-link file, but I don't know where it is, how do I do it?

Ideas:

• Find files can take advantage of the Find command.

• hard-link features do not cross the file system, so the source file is in which filesystem, right there.

• hard-link files and source files have the same inode #, you can use the find -inum parameters and -samefile parameter means according to Inode The first thing to look for is to see the file's inode

• -samefile" parameter means finding the same inode inode of a file

[[email protected] oldboy]# stat oldboy.txt  //Gets the inode number of the file   file: ' Oldboy.txt '   Size:55               Blocks: 8          IO Block: 4096    regular filedevice: 803h/2051d      inode: 148677       Links: 2Access:  (0644/-rw-r--r--)   Uid:  (    0/    root)    Gid:  (   0/     root) access: 2016-04-17 15:32:13.861206307 +0800modify: 2016-04-17  14:20:13.246213893 +0800change: 2016-04-17 16:04:17.023206128 +0800[[email protected]  oldboy]# find / -inum 1486772>/dev/null //based on inode number lookup, discard the error hint/usr/local/ Xiaoming/data/oldboy/oldboy.txt[[email protected] oldboy]# 

problem 2 : I have a file N Create a soft connection file, but I do not know where to put, and do not know what name, how to do?

Ideas:

• soft links can cross file systems, and inode, attributes are different from the source file no rules can be found

• ls–l When you view a linked file, it will: FileName---Link Filename way display.

• We look for all the link files in the current system and then filter the source file name we're looking for n

[Email protected] oldboy]# Find-type l-exec ls-l {} \; lrwxrwxrwx 1 root root 1 Apr 16:21 ./xiaohong-> 1lrwxrwxrwx 1 root root ten Apr 16:16./oldgirl.txt-oldboy.tx T[[email protected] oldboy]#//Find file, long format display, then filter source file name [[email protected] oldboy]# Find-type l-exec ls-l {}\;| grep ' old Boy.txt ' lrwxrwxrwx 1 root root, Apr 16:16./oldgirl.txt-Oldboy.txt
