github-enterprise-fetch-raw.sh

#
# a one-liner to get raw content from github enterprise, relying on basic authentication.
# eliminates the need to create an access token and incorporate it in the url.
#
#
# fill in the blanks:
#
#   USER         your login user name for authentication (you'll be prompted for password on the terminal)
#   GHE_DOMAIN   the github enterprise custom domain
#   REPO_OWNER   the user/organization that owns the repository
#   REPO_NAME    the name of the repository
#   REF          a git ref, like a branch or commitish (most of the time you'll probably want to use 'master')
#   FILE         a path for the file to fetch, including file extension. also serves as a name for the file created locally
#
curl -u "$USER" https://${GHE_DOMAIN}/raw/${REPO_OWNER}/${REPO_NAME}/${REF}/${FILE} > ${FILE}

No input, one-liner.
You can get this link by clicking the raw button in the GHE UI, just remove the token query param at the end.

curl -sfSO https://${USER}:${TOKEN}@${GHE_DOMAIN}/raw/${REPO_OWNER}/${REPO_NAME}/${REF}/${FILE}

thanx @akhi4u, but the purpose of this snippet is to avoid the inclusion of tokens in the URL (which is less suitable for enterprise workflows)

To comment on this further, you can pass the token into the Authorization header instead
