Shell script to run Python program with command line arguments

Question

I have some files in a directory which are input files for my python script:

<1.in>
<1.in.xml>
<2.in>
<2.in.xml>
<3.in>
<3.in.xml>
...
..
.

I have the following till now:

for i in $(ls dir/*.in)
do
        new = ${i%%.in}
        test.py -i $new.in.xml -o out_$new -x $new.in -c 56
done

When I run this, it does not create an output file (which is defined with -o option). The error is :

IOError: [Errno 2] No such file or directory

Any suggestions?

have you manually tried something like test.py -i 1.in.xml -o out_1 -x 1.in -c 56 ? would help you narrow down the problem — jon_darkstar

Yes I did it manually... It runs fine when I run the python code with a single input file!!! — user638501

then id have to guess new doesnt have the value you expect. can you try to echo out new right after you assign to it in each iteration? — jon_darkstar

Make sure you are opening the file for output as open(file_name, 'w') or else the file will not be created.
