This will list all broken symlinks in the james directory – from files to directories to sub-directories. An easy way to find broken symlinks is: find /home/james -xtype l When you discover broken links, you can easily delete the file. This is because the link has no contents of its own. Every attempt to access to the file will result in a 'No such file or directory' error.

How to Find and Delete Broken Linksīroken links occur when the file or folder that a symlink points to changes path or is deleted.įor example, if 'transactions.txt' moves from /home/james to /home/james/personal, the 'trans.txt' link becomes broken. The main benefit of rm over unlink is that you can remove multiple symlinks at once, like you can with files. A symlink may be a folder, but we are only concerned with the name. Note that trying to do rm james/ would result an error, because Linux will assume 'james/' is a directory, which would require other options like r and f. To remove that relationship, you can remove the linked file. How to use rm to Remove a SymlinkĪs we've seen, a symlink is just another file or folder pointing to an original file or folder. This deletes the symlink if the process is successful.Įven if the symlink is in the form of a folder, do not append '/', because Linux will assume it's a directory and unlink can't delete directories. There are two methods to remove a symlink: How to Use Unlink to Remove a Symlink You'd also see an arrow (->) at the end indicating the file/folder the simlink is pointing to. In the result, if the first character is a small letter L ('l'), it means the file/folder is a symlink. Running this command on your terminal will display the properties of the file. How to remove a symlinkīefore you'd want to remove a symlink, you may want to confirm that a file or folder is a symlink, so that you do not tamper with your files.

Any changes to this linked folder will also affect the original folder. This would create a symlinked folder called 'james' which would contain the contents of /home/james. Similar to above, we'd use: ln -s /home/james james How to Create a Symlink for a Folder – Example Command There must be a directory already called 'my-stuffs' in your current directory – if not the command will throw an error. You can as well create a linked file in a folder link this: ln -s /home/james/transactions.txt my-stuffs/trans.txt Note that this command above would create the link file trans.txt in your current directory. Any modification to trans.txt will also be reflected in the original file. How to Create a Symlink for a File – Example Command ln -s /home/james/transactions.txt trans.txtĪfter running this command, you will be able to access the /home/james/transactions.txt with trans.txt. (That is, the file or folder you want to create a shortcut for.)Īnd the last argument is the path to link itself (the shortcut). The next argument is path to the file (or folder) that you want to link. s can also be entered as -symbolic.īy default, ln command creates hard links. The -s flag specifies that the link should be soft.

The syntax for creating a symlink is: ln -s We'll also see what broken links are, and how to delete them. Let's look at the steps involved in creating and removing a symlink. Hard links are also shortcuts for files and folders, but a hard link cannot be created for a folder or file in a different file system. Soft links are similar to shortcuts, and can point to another file or directory in any file system. Some people call symlinks 'soft links' – a type of link in Linux/UNIX systems – as opposed to 'hard links.' Difference Between a Soft Link and a Hard Link Symlinks are similar to shortcuts in Windows. 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.
