Execute a statement /bin/bash seems not to work in Virtualbox client
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I do not know if AskUbuntu is the correct place to ask or Stack Overflow.
To execute a statement in Windows use : C:\Windows\System32\cmd.exe What is the equivalent in Ubuntu? I thought it was : /bin/bash but that does not work for me. I tried /bin/sh and /bin/dash ( like shown here )but without result.
In Virtualbox client I want to be able to execute a statement. For this I use pyvbox which is a Python shell for the virtualbox API.
After installing execute in statement in Virtualbox Windows client is possible with the statement :
process, stdout, stderr = gs.execute('C:\Windows\System32\cmd.exe', ['/C', 'tasklist'])
See this link
I want to something like this for VBox Ubuntu client with the statement :
process, stdout, stderr = gs.execute('/bin/bash',['echo hello world'])
which returns no output.
In VBox Ubuntu client statement :
which bash
returns :
/bin/bash
And echo hello world is executed well.
Which alternatives there might be to execute a statement in Ubuntu? Sorry if this is not the correct place to ask.

man bash
... i.e. try to adapt your code to bash -c 'echo Hello!'
Need to know more about bash?
http://tldp.org has at least two guides om bash - they will take you from a novice to an advanced level.

I interpret that as a problem caused by pyvbox - tryprocess, stdout, stderr = gs.execute('/bin/bash',['-c echo hello world'])or something similar, I suspect the first arg must be kept as is. The bare bash -c call above works. Try it out.

@Hanna. Very warm. Your suggestion did not work. But process, stdout, stderr = gs.execute('/bin/bash',['-c', 'echo hello world']) did. Thanks very much.
