[Solved] Python script for executing repetitive script input

by


You have:

  1. A program (python script)
  2. N (9) files to process with the program
  3. 1 argument (input) for the program

Now, you want to run the script from command line for N (9) files with the same argument, right?

My suggestion will be writing another script to run the script for that N files with same input argument.

A basic introduction for system command line argument:

# Module sys has to be imported:
import sys                

# Iteration over all arguments:
for eachArg in sys.argv:   
    print(eachArg)

Example call to this script :

python argumente.py python course for beginners

The output:

argumente.py
python
course
for
beginners

Now we can modify this simple example to your case. First, create a new python program and import your python script, let’s say your python program name is my_prog1.py:

import my_prog1
import os
import sys

var = sys.argv[1]

os.system('python my_prog1 file1_location' var)
os.system('python my_prog1 file2_location' var)
os.system('python my_prog1 file3_location' var)
os.system('python my_prog1 file4_location' var)
os.system('python my_prog1 file5_location' var)
os.system('python my_prog1 file6_location' var)
os.system('python my_prog1 file7_location' var)
os.system('python my_prog1 file8_location' var)
os.system('python my_prog1 file9_location' var)

where your call to this script is (let’s name this script as sample.py):

python sample.py "your input here"

Now it will get the same input and run for N files.

Since the questioner is using steghide with command and he is required to enter the passphrase every time. From the steghide doc, you can add a passphrase argument to the command. 

import os
import sys

var = sys.argv[1]

os.system('steghide extract -sf file1.jpg -p %s' %var)
os.system('steghide extract -sf file2.jpg -p %s' %var)
os.system('steghide extract -sf file3.jpg -p %s' %var)
os.system('steghide extract -sf file4.jpg -p %s' %var)
os.system('steghide extract -sf file5.jpg -p %s' %var)
os.system('steghide extract -sf file6.jpg -p %s' %var)
os.system('steghide extract -sf file7.jpg -p %s' %var)
os.system('steghide extract -sf file8.jpg -p %s' %var)
os.system('steghide extract -sf file9.jpg -p %s' %var)

Run this in command:

python sample.py "your passphrase here"
