Hello,
I have started using python recently and would like to call a short
python script via
browser using a CGI script, but initially I am trying to call the same
python script directly through python command line. The script intends
to
perform a few command line in a pipe and I have written the script (a
short
one) as follows. I would later also like to import this application to
Django.
#!/usr/bin/python
import cgi, string, os, sys, cgitb, commands, subprocess
import posixpath, macpath
#file = "x.tar.gz"
#comd = "tar -xf %s" % (file)
#os.system(comd)
#commands.getoutput('tar -xf x.tar.gz | cd demo; cp README ../')
comd = [\
"tar -xf x.tar.gz", \
"cd demo", \
"cp README ../", \
]
outFile = os.path.join(os.curdir, "output.log")
outptr = file(outFile, "w")
errFile = os.path.join(os.curdir, "error.log")
errptr = file(errFile, "w")
retval = subprocess.call(comd, 0, None, None, outptr, errptr)
errptr.close()
outptr.close()
if not retval == 0:
errptr = file(errFile, "r")
errData = errptr.read()
errptr.close()
raise Exception("Error executing command: " + repr(errData))
but after trying to execute this independently, I get the following
error
which I am unable to interpret :
Traceback (most recent call last):
File "process.py", line 18, in <module>
retval = subprocess.call(comd, 0, None, None, outptr, errptr)
File "/usr/lib/python2.5/subprocess.py", line 443, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/lib/python2.5/subprocess.py", line 593, in __init__
errread, errwrite)
File "/usr/lib/python2.5/subprocess.py", line 1135, in
_execute_child
raise child_exception
Could someone suggest where am I going wrong and if corrected, what is
the
probability of this script being compatible with being called through
the
browser. Thanking you people in advance.
Regards.
