How to Create Symlinks¶
- Symlinks in Linux, also known as symbolic links, are a special type of file that points to another file or directory.
- Basically, they are a shortcut to files that are often more convenient than accessing the original file path.
- Example: Your research group might have a shared directory which is one level up from your
/storage/coda1/p-jdoe4/0/gburdell3). Instead of navigating one level up, and then entering your shared directory, you would like your research directory right in your home folder. A symlink can achieve this.
-s to create soft links. They are much easier to work with
- To create a symlink, use the command below
ln -s <Folder or File Name> <Link Name>
lncommand creates symlinks, and the
-ssets the type of link to soft link
- The first name is your folder name, the folder you want the link to point to
- The second name is the link name. This name will show up in your current folder as the symlink. If you leave this argument as
.or empty, the link will be created in the current working directory, and the link name will be identical to the folder/file you're linking to
Example: Link a Shared Directory¶
- All research groups have a shared directory, which will be one level up from your project directory with a path similar to:
- The term
/sharedat the end of the path might differ between groups, but the shared directory will still be one level up from the individuals project directory, and therefore not convenient to access.
- Solution: To access this shared directory in your home directory, you must create a symlink using the command steps below:
- First Navigate to your home directory using
- Create the symlink with
ln -s /storage/coda1/p-jdoe4/0/shared my_link_name, where
/storage/coda1/p-jdoe4/0/sharedis replaced with the path to your groups shared directory, and
my_link_nameis replaced with the name you want to call the link that shows up in your home directory
- A link named
my_link_nameshould appear in your home directory, which you can treat like any other folder. If you enter the directory with
cd my_link_name, you should see the contents of your groups' shared directory
