PostgreSQL command line cheatsheet

PSQL

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)

exiftool : rename files in current dir to YYYY-MM-DD-HH-MM-SS-1.ext
# Function for your .zshrc file
# Requirements: install the package manager Homebrew (http://brew.sh), then install exiftool (type brew install exiftool in Terminal.app).
# Renames image and MOV files according to EXIF capture date, using YYYY-MM-DD-HH-MM-SS.ext format.
# Files shot within the same second get copy number added (-1,-2, etc.).
# Video files require a different, so we run exiftool 3 times:
# 1. Exclude MOV files and rename the image files with <CreateDate>.
# 2. Target MOV files and rename them with MediaCreateDate (for iPhone videos).
# 3. Target MOV files and rename them with DateTimeOriginal (for Fuji camera videos).

No longer able to make public gists private — message to GitHub

We've been able to toggle visibility of gists since 2014 (https://github.com/blog/1837-change-the-visibility-of-your-gists), but I just noticed that I can no longer make public gists private. That is, when I edit private gists I still see the "Make Public" button, but not the other way round — there's only a "Delete" button when I edit public gists; the "Make Secret" which should be next to it (as shown in the screencast in the linked blog post) is nowhere to be found. I made a screenshot and a screencast demonstrating the issue, both of which are attached. Could you please confirm this issue? Was this an intentional change, and why? Thank you for your attention.
