Git pre-commit hook for large files

This hook warns you before you accidentally commit large files to git. It's very hard to reverse such an accidental commit, so it's better to prevent it in advance.

Since you will likely want this script to run in all your git repos, a script is attached to add this hook to all git repos you create / clone in the future.

Of course, you can just download it directly to the hooks in an existing git repo.

If you find this script useful, you might enjoy our more heavy-duty project FastDS, which aims to make it easier to work with versioning in data science projects.

Source: http://docs.ansible.com/ansible/latest/playbooks_variables.html#variable-precedence-where-should-i-put-a-variable

From least to most important

• command line values (for example, -u my_user, these are not variables)
• role defaults (defined in role/defaults/main.yml)
• inventory file or script group vars
• inventory group_vars/all

#### Contents of the preconfiguration file (for stretch)
### Localization
# Preseeding only locale sets language, country and locale.
#d-i debian-installer/locale string en_US

# The values can also be preseeded individually for greater flexibility.
d-i debian-installer/language string en
d-i debian-installer/country string DK
d-i debian-installer/locale string en_DK.UTF-8
# Optionally specify additional locales to be generated.

# You'll be needing two machines, the target machine and source one (makes sense, right)?

#####
# On the target machine
nc -l 55555 | gzip -d -c | mysql <database name> -u<user> -p<password> [ | <decrypt> ]

#####
# On the source machine
mysqldump -u<user> -p<password> <database name> | gzip | nc <ip of target server> 55555 [ | <encrypt> ]
