My task is to run a new terminal session and in that terminal session logon to a remote server then run some commands. Example:
Terminal1:
gnome-terminal --tab --title "servername" -- /bin/sh -c "script servername.`date '+%Y_%m_%d_%H_%M_%S'`; ssh user#serverip; <execute some more commands after logon to server>"

I am wanting to run a bash script on startup in Ubuntu 20.04 with the terminal visible. The test.sh file is located at /usr/bin/test.sh. I can get the test.sh file to run at startup but not in a visible terminal window.
Contents of test.sh:
#! /bin/bash
echo "hello";
I can not get it to work, I have tried (individually):
Crontab (with and without the '&' and with/without "sudo")
#reboot bash test.sh &
#reboot /usr/bin/test.sh &
#reboot DISPLAY=:0 xterm -hold -e bash -c "bash test.sh" &
#reboot DISPLAY=:0 xterm -hold -e bash -c "bash /usr/bin/test.sh" &
Startup Applications Command
sudo bash /usr/bin/test.sh
bash /usr/bin/test.sh
/usr/bin/test.sh
Creating a Service at /etc/systemd/system/testService.service
[Unit]
Description = Test Service
[Service]
WorkingDirectory= /usr/bin
ExecStart= /usr/bin/test.sh
[Install]
WantedBy=multi-user.target
And start, enable and checked status..
systemctl start testService.service
systemctl enable testService.service
systemctl status testService.service
But failed to start.
Any help / pointing in a better direction would be appreciated!
To get a GUI terminal window to appear when you run your script:
Add to "Startup Applications" (under command):
bash test.sh
Contents of test.sh:
#! /bin/bash
DISPLAY=:0.0 xterm -hold -e bash helloWorld.sh
Contents of helloWorld.sh:
#! /bin/bash
echo "hello";
For me, this opened an XTerm terminal window upon login and ran the helloWorld.sh script.
When you start a Unix, the X server gets started at the end of the startup. And starting X clients makes only sense, when someone has logged in. So your aim "start X client when computer starts" makes no sense, because there is no X server running when you try to start the X client.
You can start X clients after login. If you use a classical installation, use .xinitrc for this. If you use a different desktop environment, use whatever this desktop environment provides you.

I use a script which after execution opens different tabs and connects to different servers(using ssh). Now along with that,I want to run another command (say 'pwd').So how to do that?
gnome-terminal --tab -e 'ssh user#ip1' --tab -e 'ssh user#ip2'
This opens 2 tabs and connects to corresponding ip.After ssh in every tab I want to run another command, so that there will be two tabs,and after connecting to ip it will run specified command
You need to use SSH ability to execute remote command, like this:
gnome-terminal --tab -e "ssh -A -t user#ipbridge \"ssh -t user#ip1 'pwd; /bin/bash -i'\""
Note the /bin/bash -i after the command. It is needed, because otherwise ssh will exit after the command.
Use ansible, fabric or any automation tool like any of these to do that you want. this tools allow execute a same command via ssh in multiple machines at same time in simple way.
using ansible you only need to do somthing like this
ansible <your-list-of machine> -m shell -a "your command"
example
ansible ip1 -m shell -a "echo $TERM"
The code is following:
gnome-terminal -x sh -c "ssh root#ip 'ls'"
And the 'ls' can executed well on the server, but after the execution it will log out the server and I want to stay in the server. So I want to know is there any way to solve this problem
Because you are supplying a command (the 'ls' part of your code) ssh will execute it on the remote server then log out of it, just as you experienced.
It you leave out the command, ssh should stay logged into the server,
gnome-terminal -x sh -c "ssh root#ip"
I am trying to call an installation of node.js on a remote server running Ubuntu via SSH. Node has been installed via nvm.
SSHing in and calling node works just fine:
user#localmachine:~$ ssh user#remoteserver
(Server welcome text)
user#remoteserver:~$ which node
/home/user/.nvm/v0.10.00/bin/node
However if I combine it into one line:
user#localmachine:~$ ssh user#remoteserver "which ls"
/bin/ls
user#localmachine:~$ ssh user#remoteserver "which node"
No sign of node, so I tried sourcing .bashrc and waiting 10 seconds:
user#localmachine:~$ ssh user#remoteserver "source ~/.bashrc; sleep 10; which node"
Only node seems affected by this. One thing I did notice was that if I ssh in and then check which shell I'm in it says -bash whilst if I ssh direct it gives me /bin/bash. I tried running the commands inside a bash login shell:
user#localmachine:~$ ssh user#remoteserver 'bash --login -c "which node"'
Still nothing.
Basically my question is: Why isn't bash finding my node.js installation when I call it non-interactively from SSH?
Another approach is to run bash in interactive mode with the -i flag:
user#localmachine:~$ ssh user#remoteserver "bash -i -c 'which node'"
/home/user/.nvm/v0.10.00/bin/node
$ ssh user#remoteserver "which node"
When you run ssh and specify a command to be run on the remote system, ssh by default doesn't allocate a PTY (pseudo-TTY) for the session. Not having a TTY causes your remote shell process (ie, bash) to initialize as a non-interactive session instead of an interactive session. This can alter how it interprets your initialization files--.bashrc, .bash_profile, and so on.
The actual problem is probably that the line which adds /home/user/.nvm/v0.10.00/bin to your command PATH isn't executing for non-interactive sessions. There are two ways to resolve this:
Find the command in your initialization file(s) which adds /home/user/.nvm/v0.10.00/bin to your command path, figure out why it's not running for non-interactive sessions, and correct it.
Run ssh with the -t option. This tells it to allocate a PTY for the remote session. Or add the line RequestTTY yes to your .ssh/config file on the local host.
I am looking to script something in batch which will need to run remote ssh commands on Linux. I would want the output returned so I can either display it on the screen or log it.
I tried putty.exe -ssh user#host -pw password -m command_run but it doesn't return anything on my screen.
Anyone done this before?
The -m switch of PuTTY takes a path to a script file as an argument, not a command.
Reference: https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-m
So you have to save your command (command_run) to a plain text file (e.g. c:\path\command.txt) and pass that to PuTTY:
putty.exe -ssh user#host -pw password -m c:\path\command.txt
Though note that you should use Plink (a command-line connection tool from PuTTY suite). It's a console application, so you can redirect its output to a file (what you cannot do with PuTTY).
A command-line syntax is identical, an output redirection added:
plink.exe -ssh user#host -pw password -m c:\path\command.txt > output.txt
See Using the command-line connection tool Plink.
And with Plink, you can actually provide the command directly on its command-line:
plink.exe -ssh user#host -pw password command > output.txt
Similar questions:

You can also use Bash on Ubuntu on Windows directly. E.g.,
bash -c "ssh -t user#computer 'cd /; sudo my-command'"
Per Martin Prikryl's comment below:
The -t enables terminal emulation. Whether you need the terminal emulation for sudo depends on configuration (and by default you do no need it, while many distributions override the default). On the contrary, many other commands need terminal emulation.
As an alternative option you could install OpenSSH http://www.mls-software.com/opensshd.html and then simply ssh user#host -pw password -m command_run
Edit: After a response from user2687375 when installing, select client only. Once this is done you should be able to initiate SSH from command.
Then you can create an ssh batch script such as
ECHO OFF
CLS
:MENU
ECHO.
ECHO ........................
ECHO SSH servers
ECHO ........................
ECHO.
ECHO 1 - Web Server 1
ECHO 2 - Web Server 2
ECHO E - EXIT
ECHO.
SET /P M=Type 1 - 2 then press ENTER:
IF %M%==1 GOTO WEB1
IF %M%==2 GOTO WEB2
IF %M%==E GOTO EOF
