Convert shell script command to command line


Tag: python,shell,sh

I am executing python script with multiple command line parameter, but using shell script.

command i execute for shell script execution is:

./scripts/ data/questions/questions.txt data/lexicons/paralex data/weights/paralex.txt data/database > output.txt files looks like below (please explain how it works):

set -u
set -e
if [ $# != 4 ]; then
    echo "Usage: questions lexicon weights db"
    exit 1
PYTHONPATH=$PWD/python python -m lex.gearman_worker $lexicon $weights $db < $questions

I tried to execute python command as below in Command line :

python -m python/lex/ data/lexicons/paralex data/weights/paralex.txt data/database > output.txt

which gives error :

/usr/bin/python: Import by filename is not supported.

Update1 : file import other files like ths:

import lex.parse
import lex.semantics
from collections import namedtuple
from collections import defaultdict

import line gives error like this:

ImportError: No module named lex.lexicon

Update2 (executed on linux terminal):

export PYTHONPATH=$/mnt/paralex-evaluation-gearman/python
PYTHONPATH = ./python python -m python/lex/gearman_worker data/lexicons/paralex data/weights/paralex.txt data/database > output.txt


PYTHONPATH: command not found


python -m python/lex/gearman_worker data/lexicons/paralex data/weights/paralex.txt data/database > output.txt


File "/mnt/paralex-evaluation-gearman/python/lex/", line 3, in <module>
    import lex.lexicon
ImportError: No module named lex.lexicon


You just need to execute the following command:

PYTHONPATH=./python python -m lex.gearman_worker ARGUMENT_2 ARGUMENT_3 ARGUMENT_4 < ARGUMENT_1

If that doesn't work then you may have to export the PYTHONPATH setting:

export PYTHONPATH=${PWD}/python
python -m lex.gearman_worker ARGUMENT_2 ARGUMENT_3 ARGUMENT_4 < ARGUMENT_1

The original arguments that you would pass to the script are listed as ARGUMENT_N.

The script just:
