Input text: test

  • Online MD5 hashsum generator: 098f6bcd4621d373cade4e832627b4f6
  • echo "test" | md5sum: d8e8fca2dc0f896fd7cb4cb0031ba249

Also the same happens to sha512sum and sha1sum.

Why does Linux and an online generator generate different hashes?

One of these is the hash of "test" and one of them is the hash of "test\n".

$ printf 'test' | md5sum
098f6bcd4621d373cade4e832627b4f6  -
$ printf 'test\n' | md5sum
d8e8fca2dc0f896fd7cb4cb0031ba249  -

echo outputs a newline character after its arguments.
