Ping bulk ULR with batch and Knime

[natanzi]

Dears,
I need to run a below batch file with KNIME, to get ping result of the many URL.
Is there any way to running batch file and get result in Knime?

@echo off
for /f "delims=" %%a in ( ' type "e:\url-list.txt" ' ) do ping -n 1 %%a >nul && (echo %%a ok) || (echo %%a failed to respond) 
pause

Save as as a .BAT:

BR,
Milad

Hi @natanzi -

You can try the Bash or External Tool nodes for this purpose.

Dear @natanzi

Alternatively to @ScottF suggestions, you may also use a Java Snippet to execute command line programs and recover their output:

The workflow with your data is run and available here:

Hope this helps.

Hi Ael,

I’ve been using something similar to this, but never collected the StdOutput of my called program. I’m gonna steal this, it’s very useful to me. Thank you =)

Thank you, it’s nice to hear that my posts are appreciated. I also learned some things, so I guess that’s a win win?
