This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:

# Creates an alias called "git hist" that outputs a nicely formatted git log. | |
# Usage is just like "git log" | |
# Examples: | |
# git hist | |
# git hist -5 | |
# git hist <branch_name> | |
# git hist <tag_name> -10 | |
## | |

Magic words:
psql -U postgres
Some interesting flags (to see all, use -h
or --help
depending on your psql version):
-E
: will describe the underlaying queries of the \
commands (cool for learning!)-l
: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
