It contains information about another file or directory. + +Links allow more than one filename to reference the same file. + +### What’s Soft link + +A symbolic link, also known as a symlink or a soft link, is a special type of file that points to another file or directory on Linux. + +It’s like a shortcut in Windows. It contains the path of the original file and not the contents. + +In general Symbolic links are used to link libraries. Also, used to link log files and folders on mounted NFS (Network File System) shares. + +### What’s Hard link + +Hard link is a mirror copy of the original file. Deleting the original file does not impact anything, because the hard link file serves as a mirror copy of the original file. + +Why would you want to create a link file instead of copying them? + +This is especially useful when you want to keep a same files in multiple location with updated contents. + +When you copy a file to another location, it will copy the content and never get updated from the source file. + +The contents of the file will be different from time to time. + +### The difference between Soft link vs Hard link + +I’ve included possible difference between soft link and hard link in the table below. + +S.No | Soft Link | Hard Link +---|---|--- +1 | The soft link is similar to the file shortcut on Windows. | Hard link is a mirror copy of the original file. +2 | Soft link can be called Symbolic link or symlink. | Hard link has no other name +3 | Changes in both file are reflected in the other. | It's like a soft link. +4 | Soft links can be created on different file systems. | Hard link can only be made on the same file system. +5 | Can create a soft link to files and directories | Only files can be linked +6 | It has different inode number and file permissions compared to the original file. | It has the same inode number and file permissions. +7 | It contains the path of the original file and not the contents. | It contains the actual contents of the original file. +8 | When the original file is removed, the link will die because it points to a non-existent file. This is called the hanging link. | Nothing happens when the original file is removed. +9 | You can create a soft link with the following command (# ln -s [Source Filename] [Link Name]) | Hard link can be created using the following command (# ln [Source Filename] [Link Name]) +10 | The soft link file contains a special symbol "l" in the file permission field. | There is no special symbol for this. +11 | You can find the soft link file with the following command (# find / -type l) | You can find the hard link file with the following command (# find / -samefile [Source Filename]) +12 | A broken soft link can be found using the following command (# symlinks [Path/to/Directory]). | Not applicable +-------------------------------------------------------------------------------- + +via: https://www.2daygeek.com/difference-between-soft-link-vs-hard-link-linux/ + +作者：[Magesh Maruthamuthu][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://www.2daygeek.com/author/magesh/ +[b]: https://github.com/lujun9972
