The script is based on sha256sum utility and allows to compare SHA 256 sums without downloading a file with the sum.

• Option 1: Download the sha256 script and add it to your PATH variable.

• Option 2: Add the following function to your .bashrc or .zshrc file:

  sha256() {
      echo "$1 $2" | sha256sum --check
  }

Make sure you have sha256sum utility installed.

You can compare SHA 256 sums in the following way:

sha256 <expected-sha-256-sum> <name-of-the-file>

The output if the sums match:

go1.13.1.linux-amd64.tar.gz: OK

The output if the sums do not match:

go1.13.1.linux-amd64.tar.gz: FAILED
