python subprocess.call() "no such file or directory"
I've found a few questions on the module but the more common problem seems to be getting the argument list right which I think I have managed (eventually)
I am trying to run a program that expects an input like this in the command line,
fits2ndf in out
with 'in' being the filepath of the file to be converted and 'out' being the path and filename to save the result to.
So using Subprocess,
subprocess.call(["fits2ndf","/media/tom_hdd/Transfer/reference.fits","/media/tom_hdd/Transfer/reference.sdf"])
this raises,
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/subprocess.py", line 493, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
Setting shell=TRUE (which I know is bad) produces the same result. Not sure if it is relevant but I am using tcsh. Any suggestions?
Edit in response to questions
I haven't permanently set the PATH however fits2ndf is part of a package of programs which I initialize using
% tcsh
% setenv STARLINK_DIR /home/tomq/star-kapuahi
% source $STARLINK_DIR/etc/login
% source $STARLINK_DIR/etc/cshrc
and normally works from within any directory without specifying the full path.
Answer
which fits2ndf will show you the path of fits2ndf.
After that you can write given full path to your code and it should work.
Ex:
~$ which mv
/bin/mv
My python code:
import subprocess
subprocess.call(["/bin/mv","/tmp/a","/tmp/b"])
