A soft or symbolic link is a real link to the original file, while a hard link is a mirror copy of the original file. If you delete the original file, the soft link has no value, because it points to a non-existent file.
To create a symbolic link on Linux, use the ln command with the -s option. For more information on the ln command, visit the ln man page or type man ln in your terminal. If you have any questions or comments, feel free to leave a comment.
A hard link is a file that points to the same underlying inode, as another file. In case you delete a file, it removes a link to the underlying inode. Whereas a symbolic link (also known as a flexible link) is a link to another file name on the file system.
Ln command to create symbolic links
Use the -s option to create a soft (symbolic) link. The -f option will force the command to overwrite a file that already exists. The source is the file or directory to which it links.
Most file systems that support hard links use reference counting. An integer value is stored with each section of physical data. This integer represents the total number of physical links that have been created to point to the data. When a new link is created, this value is incremented by one.
If you find two files with identical properties but are not sure if they are linked, use the ls -i command to see the inode number. Files that are linked together share the same inode number. The shared inode number is 2730074, which means that these files are identical data.
To create a symbolic link, pass the -s option to the ln command followed by the target file and the name of the link. In the following example, a file is symbolically linked to the bin folder. In the following example, a mounted external drive is symbolically linked to a home directory.
Hard links and symbolic links are two different methods of referring to a file on your hard drive. … A hard link is essentially a synchronized carbon copy of a file that refers directly to a file’s inode. Symbolic links, on the other hand, refer directly to the file that the inode refers to, a shortcut.
To remove a symbolic link, use the rm or unlink command followed by the name of the symbolic link as an argument. When removing a symlink that points to a directory, do not add a slash at the end of the symlink name.
Perhaps the most useful application for hard links is to allow files, programs, and scripts (i.e. short programs) to be easily accessed in a different directory than the original file or executable file (i.e. the ready-to-run version of a program ).
How do I see inodes in Linux?
How to check the inode number of the file. Use the ls command with the -i option to see the file’s inode number, which can be found in the first field of the output.
The hard link is the exact replica of the actual file it points to. Both the hard link and the linked file share the same inode. If the source file is deleted, the hard link will continue to function and you will be able to access the file until the number of hard links to the file is not 0 (zero).
To create hard links on a Linux or Unix-like system:
- Create a hard link between sfile1file and link1file, run: ln sfile1file link1file.
- To create symbolic links instead of hard links, use: ln -s source link.
- To check hard or soft links on Linux, run: ls -l source link.

- Open command prompt. Click the Windows symbol on the screen or press the Windows button on your keyboard to open the start menu. Search for cmd or command prompt. …
- Type mklink. Type mklink and specify the option. …
- Termination. The above statement will appear if the symbolic link is created successfully.
Step to create a soft link for the host program:
- Step 1: Go to the custom top as shown below:> cd $ XXCUST_TOP / bin. app01 (erpdev) /product/appl/apps/apps_st/appl/xxcust/12.0.0/bin. …
- Step 2: Use the ‘fndcpesr’ command to create a soft link. $ pwd. app01 (erpdev) /product/appl/apps/apps_st/appl/xxcust/12.0.0/bin.
