Hi again,
I have checked that the shell is the bash shell by running again
the script with a print statement. The first four lines are:
#!/usr/local/bin/python
import os
os.environ['SHELL'] = "/bin/bash"
print os.environ['SHELL']
I have also read in Internet, in the following message about a
python script:
http://www.dbforums.com/t549675.html
that the functions that execute a shell command will always invoke the Bourne
shell.
The message error 'sh: test: argument expected' comes from the sentence:
energy = atoms.GetPotentialEnergy()
in the python script I am running. Could be that this sentence is always
invoking somehow the Bourne shell?
Iván
