AI coding agents have moved from the browser into the terminal, right next to the tools we already use every day. pi is such an agent: a fast, terminal-native coding assistant that reads and writes files, runs shell commands and talks to a range of LLM providers – all from within your project directory.

What makes pi interesting is that it is scriptable and extensible. Besides its interactive TUI it offers a non-interactive mode for one-shot prompts and an RPC mode for embedding it into other tools, and it can be extended with custom tools, skills, prompt templates and themes packaged and shared through npm or git.

These are not only linux snippets but also bash snippets and snippets using tools that run under Linux, *nix or sometimes even MacOSX, I should reorder this article someday ;)

Bash Scripting

Settings for more reliable bash scripts

set -euo pipefail

this gives us …

-e: exit script if a single command fails
-u: exit script if an unset variable is used
-o pipefail: return value of a pipeline is the status of the last command to exit with a non-zero status, or zero if no command exited with a non-zero status
