如何等待一段時間，然後在 bash 腳本中開啟新終端時暫停目前工作

我有一個名為我執行的程序mdr-dev，結果打開了連接埠 1022。

打開該連接埠後，我必須讓程式保持運作以保持該連接埠開啟。 問題是它需要一些時間來執行，所以同時我應該等待它打開該連接埠！

一旦連接埠打開，我想打開一個新終端並ssh透過該連接埠連接到遠端設備。

問題是：如何為此編寫 bash 或任何其他腳本？

（我已經嘗試過使用 sleep 命令，但它似乎不起作用。）

這是我到目前為止所嘗試過的：

#!/bin/bash
echo $MDR_ROOT
mdr-dev --root --mount /opt/tile/home /home --tunnel 1022 22

在上面的命令初始化過程之後mdr-dev，我想自動打開一個新終端並運行：

ssh -p 1022 root@localhost

當然，我已經嘗試過：

--tunnel 1022 22 &
sleep 5m 
xterm -hold -e ssh -p 1022 root@localhost

但這似乎不起作用......

我應該如何進行？

由於我沒有你的mdr-dev程序，所以我很難測試它，所以這裡使用 0.1 版本。請測試並在評論中反饋。

#!/bin/bash  
#
# This script opens a port to tunnel through, then waits for the tunnel to be opened
# and then connects to the correct host using ssh

### Init ###
declare -r bDebug=false
declare szPortOpen=""
if $bDebug ; then
  set -x
  declare iDebugTimeOut=30 #seconds
fi

### Main ###
echo "$MDR_ROOT"
# open tunnel:
mdr-dev --root --mount /opt/tile/home /home --tunnel 1022 22 &

if $bDebug ; then
  read -t $iDebugTimeOut -p "Hit [Enter] to continue..."
fi

#Wait for the tunnel to open
while [ -z "$szPortOpen" ]
do
  sleep 1m
  netstat -atn | grep ":1022" | (read szPortOpen; )
  if $bDebug ; then
    echo $szPortOpen
    read -t $iDebugTimeOut -p "Hit [Enter] to continue..."
  fi
done

# Now ssh to the server 
xterm -hold -e ssh -p 1022 root@localhost
