A symbolic link, also termed a soft link, is a special kind of file that points to another file, much like
In Windows or
. Unlike a hard link, a symbolic link does not contain the data in the target file. it simply points to another entry somewhere in the file system. this difference gives symbolic links certain qualities that hard links do not have, such as the ability to link to directories, or to files on remote computers networked through
. Also, when you delete a target file, symbolic links to that file become unusable, whereas hard links preserve the contents of the file.
To create a symbolic link inUNIX, At the Unix prompt, enter the following command:
Ln-s source_file myfile
source_fileWith the name of the existing file for which you want to create the Symbolic Link (this file can be any existing file or directory authentication ss the file systems). Replace
myfileWith the name of the symbolic link.
lnCommand then creates the symbolic link. After you 've made the Symbolic Link, you can perform an operation on or execute
myfile, Just as you cocould with
source_file. You can use normal file management commands (e.g .,
rm) On the symbolic link.
Note:If you delete the source file or move it to a different location, your symbolic file will not function properly. you shoshould either delete or move it. if you try to use it for other purposes (e.g ., if you try to edit or execute it), the system will send a "file nonexistent" message.
