Today, I will talk to you about how to output symbolic links in Linux, many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

What is a symbolic link?

Symbolic link (symlink), also known as soft link, is a special file type that points to another file or directory in Linux. It is similar to shortcuts in Windows. It can point to a file or directory in the same or different file system or partition.

Symbolic links are commonly used to link library files. It can also be used to link log files and folders on mounted NFS (network file system).

What is the rm command?

The rm command is used to remove files and directories. It's very dangerous, and you have to be very careful every time you use the rm command.

What is the unlink command?

The unlink command is used to remove special files. It is installed as part of GNU Gorutils.

1) how to remove symbolic link files using the rm command

The rm command is the most frequently used command in Linux, allowing us to remove symbolic links as described below.

# rm symlinkfile

Always use the rm command with-I to understand what is being done.

# rm-I symlinkfile1rm:remove symbolic link 'symlinkfile1'?y

It allows us to remove multiple symbolic links at a time:

# rm-I symlinkfile2 symlinkfile3 rm:remove symbolic link 'symlinkfile2'?yrm:remove symbolic link' symlinkfile3'?y

1a) how to remove symbolic link directories using the rm command

This is like removing a symbolic link file. Use the following command to remove the symbolic link directory.

# rm-I symlinkdirrm:remove symbolic link 'symlinkdir'?y

Use the following command to remove multiple symbolic link directories.

# rm-I symlinkdir1 symlinkdir2rm:remove symbolic link 'symlinkdir1'?yrm:remove symbolic link' symlinkdir2'?y

If you add / at the end, the symbolic link directory will not be deleted. If you add it, you will get a mistake.

# rm-I symlinkdir/rm:cannot remove'symlinkdir/': Is a directory

You can add-r to deal with the above problems. But if you add this parameter, it will delete the contents of the target directory, and it will not delete the symbolic link file. LCTT: this may not be your original intention. )

# rm-ri symlinkdir/rm:descend into directory'symlinkdir/'?yrm:remove regular file 'symlinkdir/file4.txt'?yrm:remove directory'symlinkdir/'?yrm:cannot remove'symlinkdir/': Not a directory

2) how to remove symbolic links using the unlink command

The unlink command deletes the specified file. It accepts only one file at a time.

Delete the symbolic link file:

# unlink symlinkfile

Delete the symbolic link directory:

# unlink symlinkdir2

If you add / at the end, you cannot use the unlink command to delete the symbolic link directory.

# unlink symlinkdir3/ unlink:cannot unlink 'symlinkdir3/': Not a directory what is the Linux system Linux is a free-to-use and free-spread UNIX-like operating system, is a POSIX-based multi-user, multi-tasking, multi-threaded and multi-CPU operating system, using Linux to run major Unix tools, applications and network protocols.
