如果手动执行脚本，请键入 Y 进行删除

tag-icon • tag-icon bash scripting input interactive
如果手动执行脚本，请键入 Y 进行删除

这是一个由 2 部分组成的问题。

场景：该脚本位于 cronjob 上。如果文件夹不存在，系统会向我们发送一封电子邮件，打开一个票证，通知我们该文件夹不可用。我们必须手动登录并删除前面的文件夹 atm。

我希望我们能够手动执行脚本并通过按“Y”删除前面的文件夹，或者在我们登录并手动执行脚本时按“Enter”键继续。

这就是我到目前为止所拥有的......

   #-- check to see if cache folder exists
   { echo "Checking to see if ...";
   echo "${wDir}/${client%/}/.ftp-vendor-scripts/cache exists ... "; echo ""; } >> "$log"

   if [ ! -d "${wDir}"/"${client%/}"/.ftp-vendor-scripts/cache ]; then
      echo "Directory - ${wDir}/${client%/}/.ftp-vendor-scripts/cache DOES NOT exists - Failed ..." >> "$log";

      if [ ******** this script is being executed manually ******* ]; then
         echo "Would you like to delete the ${wDir}/${client%/}/.ftp-vendor-scripts folder?"
         echo "Press \"Y\" to delete the ${wDir}/${client%/}/.ftp-vendor-scripts."
         echo "Press \"Enter\" to continue without deleting the .ftp-vendor-scripts folder."
      else
         echo "Directory - ${wDir}/${client%/}/.ftp-vendor-scripts/cache DOES NOT exists - Failed ..." | mail -s "${wDir}/${client%/}/.ftp-vendor-scripts/ca$
      fi

   else
      echo "Directory - ${wDir}/${client%/}/.ftp-vendor-scripts/cache exists - Success ..." >> "$log";
   fi

你需要这样的东西：

#!/usr/bin/env sh

if [ -t 1 ]
then
    interactive=1
else
    interactive=0
fi


if [ "$interactive" -eq 1 ]
then
    printf "interactive\n"

    while true
    do
    printf "Rm directory? "
    read -r reply
    if [ "$reply" = "y" ]
    then
            printf "directory will be removed\n"
            break
    elif [ "$reply" = "n" ]
    then
            printf "directory will not be removed\n"
            break
    else
            printf "Uknown reply - it must be either y or n\n"
    fi
    done

else
    printf "non interactive\n"
fi

上面的脚本是POSIX兼容的，并使用shellcheck.它将检查它是否在interactive或non interactive模式下运行，可能通过cron并会采取相应的行动。我已经用 、 和 对其bash进行dash了Busybox ash测试FreeBSD。
