How to use a for loop in windows command line?

1 Answer

Best answer

Yes, For is definitely available in command prompt / batch file.
Most common way of using for loop is with a data set. It works more or less like a foreach.

General syntax goes like this,

FOR %i IN <DataSet> DO <method> %i

Here we pass a custom data set (an array),

FOR %i IN (1,2,3,4) DO echo %i

To loop through executable files,

FOR %i IN (*.exe) DO echo %i

For additional information, type "help for" in command prompt.

Hope this helps.

Running a command line program and reading the result as it runs in Python

I'm using Python 2.7 under Windows and am trying to run a command line program and process the programs output as it is running. A number of web searches have indicated that the following code would work.

import subprocess

p = subprocess.Popen("D:PythonPython27Scriptspip.exe list -o",
 stdout=subprocess.PIPE,
 stderr=subprocess.STDOUT,
 bufsize=1,
 universal_newlines=True,
 shell=False)
for line in p.stdout:
 print line

When I use this code I can see that the Popen works, any code between the Popen and the for will run straight away, but as soon as it gets to the for and tries to read p.stdout the code blocks until the command
line program completes, then all of the lines are returned. Does anyone know how to get the results of the program without it blocking?
