Windows shell for loop example (read file, run cmd, dump output)
I just retrieved this from Ed Skoudis’s presentation that I just mentioned in my previous post (look it up!)
Windows’ shell scripting is really in the dark, at least for me. I’m constantly looking for new ways of creating smart batch scripts and it really gets to be a pain in the ass to find something useful.
It is therefore a must to store the following one. It will open a file, the delimiter character is fictional, the idea is that you wont really use it - which forces windows not to parse the command using spaces as the default delimiter, the run the command and finally dump the output to a file!
c:\> for /L %i in (1,0,2) do (for /f “delims=^” %j in (commands.txt) do cmd.exe /C %j >> output.txt & del commands.txt) & ping -n 2 127.0.0.1
Goodbye!
