Shell Script Skill
シェルスクリプトの作成・レビュー・改善を行うためのスキルです。
基本方針
POSIX準拠
- 可搬性を重視
- bash拡張が必要な場合は shebang で明示
ShellCheck準拠
- 全てのスクリプトはShellCheckでエラー0を目指す
- 必要な場合のみ
# shellcheck disable=SC####で抑制
コーディング規約
変数
# 変数は常にクォート
echo "${variable}"
# ローカル変数には local を使用
local my_var="value"
# 定数は大文字
readonly MY_CONSTANT="value"
エラーハンドリング
# スクリプト先頭に設定
set -euo pipefail
# エラーメッセージは stderr へ
echo "Error: something went wrong" >&2
exit 1
関数
# 関数名はスネークケース
my_function() {
local arg1="$1"
# 処理
}
チェックリスト
- shebang は適切か（#!/bin/bash or #!/bin/sh）
-
set -euo pipefailがあるか - 変数は全てクォートされているか
- ShellCheckエラーはないか
- 実行権限の設定は適切か
