Hi i have created a batch file (run.bat) that after execution connects me to UNIX server with help of plink. But issue starts from this point i have to execute a script after connection to my server the script contains a command sudo -l. After the execution i get the error as mentioned in subject can anyone help me on this issue ??
Batch File-:
"C:\Program Files\PuTTY" plink -ssh -pw Tos#12Ts w44dvftyw#caa1607UX009.wvd.abcd.net /opt/sieb/w44dvftyw/run.sh
Script file(run.sh) -:
#!/bin/bash
sudo -l
It says
sudo: command not found
But when i run my script normally on UNIX server it runs with no issues. What am i missing here to make it work this way please help.
Scripts such as ~/.profile or ~/.bash_profile responsible for setting up the current user's PATH are run only on login shells.
Running sh -c 'somescript' (as performed by ssh host 'somescript') is neither a login shell, nor an interactive shell; thus, it does not gain the benefit of such scripts.
This means that additions to the PATH (in your case, /usr/local/bin) may not be present with commands run in this way.
Among your options:
Pass the PATH you want as part of the command to remotely run. This might look like:
plink -ssh user#host "PATH=/bin:/usr/bin:/usr/local/bin /opt/sieb/w44dvftyw/run.sh"
Embed a working value in the script you're running:
#!/bin/bash
PATH=/bin:/usr/bin:/usr/local/bin
# ...put the rest of your script here.

I have a WSL Ubuntu distro that I've set up so that when I login 4 services start working, including a web API that I can test via Swagger to verify it is up and working.
I'm at the point where what I want to do now is start WSL via a script - that is, launch my distro, have all of the services start, and do it from Python. The problem is I cannot even figure out the correct syntax to get WSL to start from PowerShell in a manner where my services start.
Side note: "services" != systemctl (or similar) calls, but just executing bash CLI commands from either my .bashrc or .profile at login.
I've put the commands to execute in .profile & .bashrc. I've configured it both for root execution and non-root user execution. I've taken the commands out of those 2 files and put it into a script in the Windows file system that I pass in on the start of wsl. And I've put that shell script in the WSL file system as well. Nothing seems to work, and sometimes the distro starts and then stops after about 30 seconds.
Some of the PS CLI commands I've tried:
Start-Job -ScriptBlock{ wsl -d distro -u root }
Start-Job -ScriptBlock{ wsl -d distro -u root 'bash -i -l -c /root/bin/start.sh'
Start-Job -ScriptBlock{ wsl -d distro -u root 'bash -i -l -c .\start.sh'
wsl -d distro -u root -- bash -i -l -c /root/bin/start.sh
wsl -d distro -u root -- bash -i -l -c .\start.sh
wsl -d distro -u root -- /root/bin/start.sh
Permutations of the above that I've tried: replace root with my default login, and turning all of the Start-Job bash options into a comma-separated list of single-quoted strings (Ex: 'bash', '-i', '-l', ... ). Nothing I launch from the CLI will allow me access to the web API that is supposed to be hosted on my distro.
Any advice on what to try next?
Not necessarily an answer here as much as troubleshooting tips which will hopefully lead to an answer:
First, most of the forms that you are using seem to be correct. The only ones that absolutely shouldn't work are those that attempt to run the script from the Windows filesystem.
Make sure that you have a shebang line starting your script. I'm assuming you do, but other readers may come across this as well. For the moment, try this form:
#!/usr/bin/env -S bash -li
That's going to have the same effect as the bash -li you tried -- It will source both both interactive startup files such as ~/.bashrc as well as login profiles such as ~/.bash_profile (and /etc/profile.d/*, etc.).
Note that preferably, you won't need the -li. Best practice would be to move anything necessary for the services over from the startup scripts to your start.sh script, and avoid parsing the profile and rc. I need to go update some of my answers, since I just realized I've been guilty of giving some potentially bad advice ...
Specifically, though, I'm wondering if your interactive Bash config has something truly, well, "interactive" in it that might be preventing the automatic running of the script itself. Again, best practice would be for ~/.bashrc to only hold configuration that is needed for interactive shell sessions.
Make sure the script is set as executable (chmod +x start.sh). Again, I'm assuming this is the case for you.
With a shebang line and an executable script, use something like:
wsl -d distro -u root -e /root/bin/start.sh
The -e tells WSL to launch the script directly. Since it has a shebang line, it will be parsed by Bash. Most of the other forms you use above actually run Bash twice - Once when launching WSL and another when it finds the shebang line in the script.
Try some basic troubleshooting for your script like:
Add set -x to the top (right under the shebang line) to turn on script debugging.
Add a ps -efH at the end to show the processes that are running when the script completes
If needed, resort to quick-and-dirty echo statements to show where things have progressed in the script.
I'm hopeful that the above will at least show you the problem, but if not, add the debugging info that you gain from this to your question, and we can troubleshoot further.
I want to run multiple commands automatically like sudo bash, ssh server01, ls , cd /tmp etc at server login..
I am using Remote command option under SSH in putty.
I tried multiple commands with delimiter && but not working.
There is a some information lacking in your question.
You say you want to run sudo bash, then ssh server01.
Will sudo prompt for a password in your remote server?
Assuming there is no password in sudo, running bash will open another shell waiting for user input. The command ssh server01 will not be run until that bash shell is exited.
If you want to run 2 commands, try first simpler ones like:
ls -l /tmp ; echo "hi there"
or if you prefer:
ls -l /tmp && echo "hi there"
Does this work?
If what you want is to run ssh after running bash, you can try :
sudo bash -c "ssh server01"
That is probably because the command is expected to be a program name followed by parameters, which will be passed directly to the program. In order to get && and other functionality that is provided by a command line interpreter such as bash, try this:
/bin/bash -c "command1 && command2"
I tried what I suggested in my previous answer.
It is possible to run 2 simple commands in putty separated by a semicolon. As in my example I tried with ls and echo. The remote server runs them and then the session closes.
I also tried to ssh to a remote server that is configured for not asking for a password. In that case, it also works, I get connected to the 2nd server and I can run commands on it. Upon exit, the 2 connections are closed.
So please, let us know what you actually need / want.
You can execute two consecutive commands in PuTTY using a regular shell syntax. E.g. using ; or &&.
But you want to execute ssh server01 in sudo bash shell, right?
These are not two consecutive commands, it's ssh server01 command executed within sudo bash.
So you have to use a sudo command-line syntax to execute the ssh server01, like
sudo bash ssh server01
In the case when I first ssh to the server and then run command, it executes successfully
root#chef:~# chef-solo -v
Chef: 11.10.0
But when I try to run it like this
ssh root#188.xxx.xxx.xxx -t -C "chef-solo -c /var/chef/solo.rb"
I receive an error:
bash: chef-solo: command not found
Why is this happening, and how can I solve this issue ?
It is still matter of $PATH and ssh - not chef-solo. Interactive and non-interactive sessions not necessarily have same value for the $PATH variable. Same ssh problem is described here on stackoverflow. You may also check GNU bash manual to have deeper insight of (non-)interactive and (non-)login shells. To shorten, solution would be one of the following:
Run chef-solo using absolute path. Here's how your command might look like:
ssh root#188.xxx.xxx.xxx -t -C "/usr/local/ruby/bin/chef-solo -c /var/chef/solo.rb"
Tune the .bash configuration files to load same $PATH variable for both interactive and non-interactive shells.
Note: To find out what's the absolute path, login to the machine via ssh and run which chef-solo (Don't know how experienced you are with linux. Sorry if I'm underestimating your knowledge)
I am trying to have my Ubuntu 12.04 LTS server run a bash script I have to start a Minecraft server on start up, prior to log in but as user minecraft. I can have it run as root by placing the following in /etc/rc.local
bash /path/to/script/script.sh
which runs the script as root, I have tried the following in /etc/rc.local
su -c `bash /path/to/script/script.sh` minecraft
but to no avail. Can anyone tell me what I am doing wrong or should be doing instead? The first line of my script is
#!/bin/bash
in case it is important. Thanks much!
Try
su minecraft -c '/bin/bash /path/to/script/script.sh &'
The user should be the first argument to su.
You should use quotes and not ticks for the command argument (-c)
You may want to consider using su -l minecraft to have the script run in an environment which would be similar to that if the user minecraft logged in directly.
Give this a shot and let me know if it works.
I am developing a TIBCO application and need to be able to run a scp command from an external command resource.
Anyway the issue boils down to being able to log in to bash.exe then run my scp command in the same line.
it works when I run (from cmd.exe)
c:\cygwin\bin\bash.exe --login
(I enter bash)
Then I can run my scp statement just fine
scp account#server:~mysourcedirectory/targetfilename* /cygdrive/c/targetfolder
I want to do these two things in the same line but it doesnt work, aka
c:\cygwin\bin\bash.exe --login -c scp account#server:~mysourcedirectory/targetfilename* /cygdrive/c/targetfolder
will fail. What am I doing wrong and how can i run this command in one go?
Thanks
You have to quote the command.
c:\cygwin\bin\bash.exe --login -c "scp account#server:~mysourcedirectory/targetfilename* /cygdrive/c/targetfolder"
Tested using cmd in wine in gnu/linux. Single quotes did not work, I don't know all the quoting rules for cmd. But the above did work.
