Gemini CLIAbout this skill
Use when: writing, reviewing, or fixing shell scripts that must run on more than one shell or OS — POSIX sh vs bash/ksh/zsh, dash/ash/busybox as /bin/sh, GNU vs BSD/macOS vs busybox coreutils, CI containers, Alpine, or unknown targets. Covers bashisms, non-portable utility flags (readlink -f, sed -i, grep -P, date -d), shebang and interpreter targeting, locale and word-splitting hazards, and portable replacements.
