使用ssh在远程机器上运行命令

i want to run some command on several machine using ssh. I know it can be done by just using the command "ssh user@hostname command". However, the command i want to run print some string on the console. Is there any way that send all the strings back to the console that i'm on?

我想使用ssh在几台机器上运行一些命令。我知道只需使用命令“ssh user @ hostname”即可完成。但是,我想要运行的命令在控制台上打印一些字符串。有没有办法将所有字符串发送回我正在使用的控制台?

5 个解决方案

You could run the commands in a screen:

您可以在屏幕上运行命令:

screen -S test
ssh user@hostname command1
ssh user@hostname2 command2

You can then detach (Ctrl-D) from the screen, let it run for however long it will run, then re-attach (screen -r test) to the screen and see all of the output. This assumes that you won't have a ton of output from the commands, however. Here's a link to a tutorial on screen.

然后,您可以从屏幕上分离(Ctrl-D),让它运行不管它运行多久,然后重新连接(屏幕-r test)到屏幕上并查看所有输出。但是,假设您不会从命令中获得大量输出。这是屏幕上教程的链接。

 ssh user@hostname command

Does just that. if 'command' outputs something, it'll show on the terminal you ran ssh from. Try e.g. ssh user@hostname ls -l

就是这样。如果'command'输出某些内容,它将显示在您运行ssh的终端上。尝试例如ssh user @ hostname ls -l

But as others have said, GNU screen is invaluable for this type of work.

但正如其他人所说,GNU屏幕对于这类工作是非常宝贵的。

#3

You probably want to use Gnu Screen for this. You can start a process in a "virtual" terminal, "detach" the terminal and log out for however long you want... Then you can ssh back in and re-attach the terminal to see the console output.

您可能想要使用Gnu Screen。您可以在“虚拟”终端中启动进程,“分离”终端并注销您想要的时间...然后您可以重新连接并重新连接终端以查看控制台输出。

#4

Also have a look at nohup, for example:

还要看看nohup,例如:

ssh user@domain.com nohup script_that_outputs_strings.py > the_strings.txt

ssh user@domain.com nohup script_that_outputs_strings.py> the_strings.txt

Then if you want to go back and monitor the progress, you could check back and tail the file or scp the output back to your local machine.

然后,如果要返回并监视进度,可以检查并拖尾文件或将输出scp返回到本地计算机。

Why don't you send you an email back? Or use a log file, and scp it to your current computer? otherwise, I don't know!

你为什么不给你发回电子邮件?或使用日志文件,并将其scp到您当前的计算机?否则,我不知道!
