Explain symbolic links permissions.

Symbolic links (or symlinks) in Linux are special types of files that point to another file or directory. When it comes to permissions, symbolic links behave a bit differently than regular files or directories.

Key Points about Symbolic Links Permissions:

Permissions of the Symlink:
- The permissions of a symbolic link are typically not relevant. When you check the permissions of a symlink using ls -l, you may see something like this:
```
lrwxrwxrwx 1 user group 11 Oct  1 12:00 symlink_name -> target_file
```
- The l at the beginning indicates it's a symlink, but the permissions (rwxrwxrwx) are usually ignored.
Access Control:
- The permissions that matter are those of the target file or directory that the symlink points to. When you access a symlink, the system checks the permissions of the target file.
- For example, if a symlink points to a file that has read permissions for the user, the user can read the symlink. If the target file does not have the appropriate permissions, access will be denied.
Creating Symlinks:
- You can create a symbolic link using the ln -s command:
```
ln -s target_file symlink_name
```

Example:

If you have a file file.txt with permissions -rw-r--r-- (owner can read/write, group and others can read), and you create a symlink to it:

ln -s file.txt symlink_to_file

The symlink symlink_to_file will show permissions like lrwxrwxrwx, but when you try to access it, the system will check the permissions of file.txt.

Summary:

Symbolic links themselves have permissions that are generally ignored.
Access is determined by the permissions of the target file or directory.
