cli

A second year of CLI picks from the Perl Toolchain Summit — terminals, JSON tools, version control, agent sandboxes, and a shell trick worth knowing. Each pick comes with a short description and a link.

When multiple versions of the same executable exist in your $PATH, the ‘is’ utility provides a clean way to discover all versions and their locations. This post demonstrates how ‘is’ can help identify version conflicts, clean up redundant installations, and streamline executable management with tabular and JSON output formats.

At the Perl Toolchain Summit a few of us shared our favourite command-line tools and terminal configurations. This compilation covers recommendations from Paul Johnson, Shawn Sorichetti, Mickey Nasriachi, Julien Fiegehenn, and Olaf Alders, including GPU-accelerated terminal emulators like WezTerm, file managers like yazi, advanced Neovim plugins, Git utilities, and system monitoring tools. Each tool includes descriptions and links for practical implementation.

The new “is battery” and “is known battery” subcommands can detect battery attributes with a clean, readable syntax. This post walks through practical examples of replacing complex shell commands with these new subcommands, demonstrating how they simplify a SketchyBar configuration on macOS. Learn how to check battery charge levels, charging state, and even conditionally load menu bar items based on whether your device has a battery.
