Linux 从 bash shell 启动一个新的 bash shell

Starting a new bash shell from a bash shell

提问by providence

I would like to run a program from the bash shell. When the program runs, it dominates the entire shell, so I would like to start a new shell and run the program from there. Currently I am doing:

我想从 bash shell 运行一个程序。当程序运行时，它支配了整个shell，所以我想启动一个新的shell并从那里运行程序。目前我正在做：

gnome-terminal -x "cd Dropbox; program_name"

However that give me the error Failed to execute the child process, no such file or directory. I believe thats because the new terminal has no time to initialize. How can I fix this?

但是，这给了我错误无法执行子进程，没有这样的文件或目录。我相信那是因为新终端没有时间初始化。我怎样才能解决这个问题？

I admit this doesn't really answer your question, but I think it solves your problem.

我承认这并不能真正回答您的问题，但我认为它可以解决您的问题。

Why not just use &to send it to the background. You can see if it's still running with jobsand bring it back to the foreground with fg, you can also send it back to the background, by first stopping it with Ctrl+Zthen bg

为什么不只是&用来将它发送到后台。您可以查看它是否仍在运行jobs并使用 将其带回前台fg，您也可以将其发送回后台，首先使用Ctrl+Z然后停止它bg

Example to try.

尝试的例子。

> sleep 20 &
> jobs
> fg [jobNumber]
[Ctrl-Z]
> jobs
> bg [jobNumber]
> jobs

use the absolute path to the program or cd before calling gnome-terminal. And you need a & to put it in the background.

在调用 gnome-terminal 之前使用程序或 cd 的绝对路径。你需要一个 & 把它放在后台。

cd Dropbox; gnome-terminal -x "program_name" &

Try adding "&" at the end of your command, e.g.:

尝试在命令末尾添加“&”，例如：

gnome-terminal &

I don't know if it's working with gnome-terminal, but it worked well with mrxvt.

我不知道它是否适用于 gnome-terminal，但它适用于 mrxvt。

Try screen. Its a simple brogram that allows you to keep track of multiple shells at the same time. You can navigate through each of the open shells and even leave the session and reconnect later on.

试试屏幕。它是一个简单的brogram，可让您同时跟踪多个shell。您可以浏览每个打开的 shell，甚至可以离开会话并稍后重新连接。

/bin/bash -c "/path/to/prog"

But look into the sleepcommand also.

但sleep也要查看命令。
