bash で yesno

Last updated at Posted at 2014-10-20

LICENSE は NYSL / CC0 / THE BEER-WARE LICENSE とか適当に好きなの選んでください。

適宜 yeno を記載した functions.sh 作って、 source /path/to/functions.sh すると良いのかな。

コード

#! /usr/bin/env bash

function yesno() {
    printf '処理を開始します。 (Y/n) >> '
    read answer
    answer=`printf $answer | grep -iE '^(yes|y|no|n)$' | tr "[:lower:]" "[:upper:]"`
    case "$answer" in
        "Y" | "YES") return 0;;
        "N" | "NO") return 1;;
        *) yesno;;
    esac
}

yesno && echo 'yes'

使用例

$ ./yesno.sh
処理を開始します。 (Y/n) >> y
yes

THX: Shell

僕が所属している会社社員募集中みたいです。なんか、 Python とか何か書いてみてーなと思った人は応募してみてくださいな。 (すてま)
