type l ! -exec test -e portion of that command turns into a "remove filename" command. It's longer than the earlier one, but should do the same thing: $ find. You can also find broken symlinks with a command like this one. To avoid running into errors when the command tries to look into files or directories that you don't have permission to examine, you can send all error output to /dev/null like this: $ find. The command shown below, on the other hand, looks in the current directory for symlinks that point to files that don't exist: $ find.
The "l" (lowercase L) tells the find command to look for symbolic links. This command lists symlinks in the current directory: $ find. The find command has an option that allows you to locate symlinks that point to files that no longer exist. The rwxrwxrwx permissions are standard and don't reflect the permissions on the file the symlink points at.

Similarly, if you use commands like cat, more, head or tail, you'll be looking at the content of the referenced file.Ĭat: loopy: Too many levels of symbolic links
#Symbolic linker vs symlinker how to#
Linux systems know how to work with symlinks and simply do the right thing. If you issue a command like "vi ref1" (where ref1 is the name of a symlink), you will end up editing whatever file ref1 points to, not the contents of the symlink itself. ref-2020, it will be only 10 characters in length. If a file named ref1 points to a file named /apps/refs/ref-2020, ref1 will be 19 characters long even if the ref-2020 file is 2 terabytes. In fact, all a symlink really contains is the name of whatever file it points to, generally along with the file system path (relative to the current location or absolute). Generally referred to as a "symlink" or "soft link", symbolic links are very small files. They can help you remember where important files are located on a system, make it easier for you to access those files and save you a good amount of disk space and trouble by making it unnecessary for you to copy large files just to make them a little more accessible. Symbolic links play a very useful role on Linux systems.
