Article of the week: A Brief History of the ‘ls’ command

The ls command, which lists files, is one of the most essential utilities for Unix and Linux users and, not surprisingly, one of the oldest. In its earliest form it was called listf and was available on the Massachusetts Institute of Technology’s Compatible Time Sharing System (CTSS) by July, 1961.

Tip of the week: Managing your passphrase-protected ssh keys with Keychain:

Interacting with ssh-agent can be confusing, using keychain to manage your ssh keys means only entering your passphrase once, at boot time. Add the following to your .bashrc or .zshrc:

# macOS
eval "$(keychain --eval --ignore-missing --quiet --inherit any id_rsa id_ed25519 google_compute_engine)"
# Linux
eval "$(keychain --eval --ignore-missing --quiet id_rsa id_ed25519 google_compute_engine)"

If you’re not a CLI purist, 1Password can also manage your ssh keys in the same way.
