Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git

How to check a file's shasum

How to check file integrity with shasum


For verifying the integrity (but not authenticity of data, i.e., who authored it or the origin of the file) of a file, it is necessary to run a checksum function on the file which will output a value and compare it to a previously stored checksum value; if both values match, we can be relatively confident that the file hasn't been tampered with or altered.

You might be asked to verify a file's sha1sum or sha2sum–-all this means is calculating and verifying the cryptographic sha1 or sha2 hash value or digest included in the file.

Various commands and methods for verifying shasum 1 or 2:
