Bashでawkを用いて各行の先頭に#を追加しRubyのコメントアウトする

More than 1 year has passed since last update.

Bashでawkを用いて各行の先頭に#を追加しRubyのコメントアウトする。
Rubyで複数行コメントアウトしたい時に使う。

bash
cat|awk '{print "#" $0}'

=>

p 1
puts 1
p 'あ'
p 'a'
p *1..5
p *'あ'..'お'
p *'a'..'e'

p 1

puts 1

p 'あ'

p 'a'

p *1..5

p *'あ'..'お'

p *'a'..'e'

参考
- AWK で行の先頭に文字列を追加する - Sarchitect

"テキストファイルの各行の先頭に文字列を追加する。

$ awk '{print "- " $0}' example.txt"

"$0
組み込み変数 $0 は、入力行(レコード)を表します。"

そのものを表示したいのになぁ…

"# コメント
-- 1行コメントは「#」のあとに書く"
