一种简单的方法是使用xargs-p或gnu-parallel-interactive。

我更喜欢xargs的行为，因为它像其他交互式unix命令一样，在提示符后立即执行每个命令，而不是收集yes以在最后运行。（在完成所需任务后，可以按Ctrl-C键。）

例如。，

echo *.xml | xargs -p -n 1 -J {} mv {} backup/

作为单行命令的朋友，我使用了以下命令：

while [ -z $prompt ]; do read -p "Continue (y/n)?" choice;case "$choice" in y|Y ) prompt=true; break;; n|N ) exit 0;; esac; done; prompt=;

以长格式编写，其工作原理如下：

while [ -z $prompt ];
  do read -p "Continue (y/n)?" choice;
  case "$choice" in
    y|Y ) prompt=true; break;;
    n|N ) exit 0;;
  esac;
done;
prompt=;

您可以在读取时使用默认REPLY，将其转换为小写，并使用表达式与一组变量进行比较。该脚本还支持ja/si/oui

read -rp "Do you want a demo? [y/n/c] "

[[ ${REPLY,,} =~ ^(c|cancel)$ ]] && { echo "Selected Cancel"; exit 1; }

if [[ ${REPLY,,} =~ ^(y|yes|j|ja|s|si|o|oui)$ ]]; then
   echo "Positive"
fi

此解决方案读取单个字符，并在yes响应时调用函数。

read -p "Are you sure? (y/n) " -n 1
echo
if [[ $REPLY =~ ^[Yy]$ ]]; then
    do_something      
fi

要获得像inputbox这样的漂亮ncurses，请使用如下命令对话框：

#!/bin/bash
if (dialog --title "Message" --yesno "Want to do something risky?" 6 25)
# message box will have the size 25x6 characters
then 
    echo "Let's do something risky"
    # do something risky
else 
    echo "Let's stay boring"
fi

默认情况下，对话框包至少在SUSE Linux上安装。看起来像：

更通用的是：

function menu(){
    title="Question time"
    prompt="Select:"
    options=("Yes" "No" "Maybe")
    echo "$title"
    PS3="$prompt"
    select opt in "${options[@]}" "Quit/Cancel"; do
        case "$REPLY" in
            1 ) echo "You picked $opt which is option $REPLY";;
            2 ) echo "You picked $opt which is option $REPLY";;
            3 ) echo "You picked $opt which is option $REPLY";;
            $(( ${#options[@]}+1 )) ) clear; echo "Goodbye!"; exit;;
            *) echo "Invalid option. Try another one.";continue;;
         esac
     done
     return
}
