Have you ever wanted to just have a list of the machines on your network? One that you could easily pass to a script / application? Well I sure have.  So I do the net view > outfile.txt then scrub the text file dance. All I really want is a list of the machine names. No \\ in front of the names. No description of the systems either. I want to go from this:

\\comp1                my computer
\\comp3                test machine

to this:


So today I decided to write a little crap script to do this for me in one step. I know it isn’t pretty but I don’t really care. I just want it to work. The good thing is that I can now use the same kind of code in some of my other scripts and I don’t even need it to write to a file at all.

#!/usr/bin/env python
import os

outfile = open(r'pyNetView.txt', 'w')

indata = os.popen('net view')

for line in indata:
    if line.startswith('\\'):
        line = line.split()
        clean = line[0][2:]
        outfile.write(clean + '\n')


Comments are welcome. Use it if you want.

    Here is a 1 liner to replace your script assuming this is from a ‘nix box:
    net view | awk ‘/^\\/{print $1}’ | sed -e ‘s:^\\\\::g’ > pyNetView.txt

    Sorry but you’ll need to manually fix the quoting. WordPress breaks it. You can prevent wordpress from doing that by following the advice here:

    stgraber@sahal:~$ cat test | cut -d ” ” -f1 | sed “s/\\\//g”

    You can then use: net view | cut -d ” ” -f1 | sed “s/\\\//g”

    I agree will all of the comments so far but I was doing this on a Windows XP box. On a Linux box it would be a different deal all together 🙂

    net view | cut -d ” ” -f1 | cut -d “\\” -f3
    this is another way to go about it.
    And you can do this is on windows as well (thanks to gnuwin32 (native) or u may also use cygwin)

  9. #9 by Jeff Schroeder on January 23, 2009 - 12:07 am install these and put them in somewhere like C:\windows\system32 and my comment still should work

    Your script in a full function Python style :
    #!/usr/bin/env python
    import os
    open(r’pyNetView.txt’, ‘w’).write(‘\n’.join([line.split()[0][2:] for line in os.popen(‘net view’) if line.startswith(‘\\’)]))

    awk (use gawk for windows) can do it all in one command 🙂
    awk ‘/\\\\/{ print substr($1,3)}’
