Hard link:

echo "111" > test.txt
ln test.txt hlinkToTest
rm -rf test.txt
cat hlinkToTest

Hardlink links to the content of the file. You can access content until the very last of the hard links exist.

Hard link       OriginalFilename (test.txt)
    \          /
    _\|      |/_

echo "111" > test.txt
ln test.txt slinkToTest
rm -rf test.txt
cat slinkToTest

Does to work because slinkToTest linked to test.txt name, not to the file content itself.

Softlink links to other filename, not to content itself. Soft link can’t access the content of riginalFilename if OriginalFilename is deleted.
