从脚本向新终端发送一系列命令 [英] Send a sequence of commands to a new terminal from a script

问题描述

我有一个脚本，我想在最后添加一个关闭计时器，我希望倒计时在新的终端窗口中运行，以便我可以取消它，因为脚本通常会在后台运行.

问题来了，

一个只包含以下内容的简单脚本

secs=$((60))而 [ $secs -gt 0 ];做echo -ne "$secs\033[0K\r"睡觉 1: $((秒--))完毕现在关机

工作正常，但如果我尝试将其发送到这样的新终端

gnome-terminal -e "bash -c'秒=$((60))而 [ $secs -gt 0 ];做echo -ne \"$secs\033[0K\r\"睡觉 1: $((秒--))完毕立即关机'"

它失败了，只是关闭了.如果我删除关闭行，我会收到此错误:

选项-e"已弃用，可能会在 gnome-terminal 的更高版本中删除.使用--"终止选项并在其后执行命令行.

有谁知道我该如何解决这个问题?

谢谢

解决方案

最简单的方法是导出一个函数:

倒计时(){秒=60而 (( 秒 > 0 ));做printf '%s\033[0K\r' "$secs"睡觉 1((秒--))完毕现在关机}导出 -f 倒计时gnome-terminal -- bash -c 倒计时

I have a script to which I wanna add a shutdown timer at the end, I'd like the countdown to run in a new terminal windows so I can cancel it since the script will usually be run in the background.

Here's the problem,

a simple script containing only the following

secs=$((60))
while [ $secs -gt 0 ]; do
   echo -ne "$secs\033[0K\r"
   sleep 1
   : $((secs--))
done
shutdown now

works fine, but if I try to send it to a new terminal like this

gnome-terminal -e "bash -c
'secs=$((60))
while [ $secs -gt 0 ]; do
   echo -ne \"$secs\033[0K\r\"
   sleep 1
   : $((secs--))
done
shutdown now'"

it fails and just shuts down. If I remove the shutdown line I get this error :

Option "-e" is deprecated and might be removed in a later version of gnome-terminal.
Use "-- " to terminate the options and put the command line to execute after it.

Does anyone know how I could fix this?

thanks

解决方案

The easy way to do this is to export a function:

countdown() {
  secs=60
  while (( secs > 0 )); do
     printf '%s\033[0K\r' "$secs"
     sleep 1
     ((secs--))
  done
  shutdown now
}
export -f countdown

gnome-terminal -- bash -c countdown
