Without the -R switch, the behavior of cp -H and cp -L is identical.
With the -R switch, cp -H only dereferences symbolic links that occur in the cp command itself, while -L also dereferences symbolic links inside the recursively copied directories.
The command
cp -R -H source/ dest/
will copy the directory source and all its contents inside the directory dest. If source is a symlink to a directory, cp will dereference the symlink, i.e., copy the directory source points to. However, if cp encounters any symlinks in source's subdirectories, it will create symlinks in the destination folder.
The command
cp -R -L source/ dest/
behaves similarly. However, it will also dereference symlinks in source's subdirectories, i.e., copy the files those symlinks point to.
