GnuPG pinentry script for terminal or graphical interface based on $PINENTRY_USER_DATA.
# ~/.bashrc: executed by bash(1) for non-login shells.
# If file exists (likely) copy fragment below into existing script:
# If stdin is a terminal
if [ -t 0 ]; then
# Set GPG_TTY so gpg-agent knows where to prompt. See gpg-agent(1)
export GPG_TTY="$(tty)"
# Set PINENTRY_USER_DATA so pinentry-auto knows to present a text UI.

How to compute the SHA256 hash for a new Nix package?

How does one find the sha256 of a new package?
