Get the MD5 of a file via this command; change .bash_profile to match the actual path and file name of the file you want to check:

md5 .bash_profile

The returned output md5 command should look something like this:

MD5 (.bash_profile) = da4b8a88ad68b6c11a05e4956677c73e

If you need a simpler form of output just run md5 with the -r command like this:

md5 -r .bash_profile

The output would look something like this which is cleaner and nicer to use for some programming purposes:

da4b8a88ad68b6c11a05e4956677c73e .bash_profile

You can also use the openssl command to get an MD5 like this:

openssl md5 .bash_profile

The returned output of that openssl command should look something like this:

MD5(.bash_profile)= da4b8a88ad68b6c11a05e4956677c73e
