Best answer: How do I create a soft link in Linux?

To create a symbolic link, use the -s ( –symbolic ) option. If both the FILE and LINK are given, ln will create a link from the file specified as the first argument ( FILE ) to the file specified as the second argument ( LINK ).

Well, the command “ln -s” offers you a solution by letting you create a soft link. The ln command in Linux creates links between files/directory. The argument “s” makes the the link symbolic or soft link instead of hard link.

A symlink (also called a symbolic link) is a type of file in Linux that points to another file or a folder on your computer. Symlinks are similar to shortcuts in Windows. Some people call symlinks “soft links” – a type of link in Linux/UNIX systems – as opposed to “hard links.”

What is Soft Link And Hard Link In Linux? A symbolic or soft link is an actual link to the original file, whereas 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.

The major difference between a hard link and soft link is that hard link is the direct reference to the file whereas soft link is the reference by name which means it points to a file by file name. Hard link links the files and directories in the same file system, but the Soft link can traverse file system boundaries.

To create a symbolic link pass the -s option to the ln command followed by the target file and the name of link. In the following example a file is symlinked into the bin folder. In the following example a mounted external drive is symlinked into a home directory.

Example

  1. Open Command Prompt. Click on the Windows symbol on the screen or press the Windows button on your keyboard to open the start-up menu. Search cmd or Command Prompt. …
  2. Write mklink. Write mklink and specify the option. …
  3. Completion. The above statement will appear if the symbolic link is created successfully.

Most file systems that support hard links use reference counting. An integer value is stored with each physical data section. This integer represents the total number of hard links that have been created to point to the data. When a new link is created, this value is increased by one.

To remove a symbolic link, use either the rm or unlink command followed by the name of the symlink as an argument. When removing a symbolic link that points to a directory do not append a trailing slash to the symlink name.

Soft Link contains the path for original file and not the contents. Removing soft link doesn’t affect anything but removing original file, the link becomes “dangling” link which points to nonexistent file. A soft link can link to a directory.

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 from the original file or executable file (i.e., the ready-to-run version of a program).

If you find two files with identical properties but are unsure if they are hard-linked, use the ls -i command to view the inode number. Files that are hard-linked together share the same inode number. The shared inode number is 2730074, meaning these files are identical data.

To make links between files you need to use ln command. A symbolic link (also known as a soft link or symlink) consists of a special type of file that serves as a reference to another file or directory.

Getting help about the ln command.

ln command option Description
-L dereference TARGETs that are symbolic links

You can check if a file is a symlink with [ -L file ] . Similarly, you can test if a file is a regular file with [ -f file ] , but in that case, the check is done after resolving symlinks. hardlinks are not a type of file, they are just different names for a file (of any type).
