db:migrate runs (single) migrations that have not run yet.

db:create creates the database

db:drop deletes the database

db:schema:load creates tables and columns within the existing database following schema.rb. This will delete existing data.

db:setup does db:create, db:schema:load, db:seed

db:reset does db:drop, db:setup

db:migrate:reset does db:drop, db:create, db:migrate

db:create creates the database for the current env

db:create:all creates the databases for all envs

db:drop drops the database for the current env

db:drop:all drops the databases for all envs

db:migrate runs migrations for the current env that have not run yet

db:migrate:up runs one specific migration

db:migrate:down rolls back one specific migration

db:migrate:status shows current migration status

db:rollback rolls back the last migration

db:forward advances the current schema version to the next one

db:seed (only) runs the db/seed.rb file

db:schema:load loads the schema into the current env's database

db:schema:dump dumps the current env's schema (and seems to create the db as well)

db:setup runs db:create db:schema:load db:seed

db:reset runs db:drop db:setup

db:migrate:redo runs (db:migrate:down db:migrate:up) or (db:rollback db:migrate) depending on the specified migration

db:migrate:reset runs db:drop db:create db:migrate

# Remember the blank line between the title and the body.

# Body: Explain *what* and *why* (not *how*). Include task ID (Jira issue).
# Wrap at 72 chars. ################################## which is here:  #


# At the end: Include Co-authored-by for all contributors. 
# Include at least one empty line before it. Format:

#
# How to Write a Git Commit Message:
# https://chris.beams.io/posts/git-commit/
#
# 1. Separate the subject from the body with a blank line
# 2. Limit the subject line to 50 characters
# 3. Capitalize the subject line
# 4. Do not end the subject line with a period
# 5. Use the imperative mood in the subject line
# 6. Wrap the body at 72 characters
# 7. Use the body to explain what and why vs. how

When you’re working on a local feature branch, do you sometimes want to pick out code changes you want to commit, but leave other changes uncommitted? With the git add -p  command, that’s exactly what you can do.

git branch -m oldName newName
git branch -m newName #Current branch

git branch -d branchName

git reset --hard # removes staged and working directory changes

## !! be very careful with these !!
## you may end up deleting what you don't want to
## read comments and manual.
git clean -f -d # remove untracked
git clean -f -x -d # CAUTION: as above but removes ignored files like config.
git clean -fxd :/ # CAUTION: as above, but cleans untracked and ignored files through the entire repo (without :/, the operation affects only the current directory)
