Re: Interactive Remote command execution through wmic
Thanks for the quick reply aGerman. I just used finding a file as an example to make things simpler to explain.
Since I have your attention, maybe you can still help.
I am ultimately trying to to execute commands on remote machines conveniently. I thought psexec would work (System Internals utility), however, I kept getting the below errors even when the syntax was correctERROR: Input redirection is not supported, exiting the process immediately.
So, I thought I would make my own psexec replacement revolved around wmic. I am able to use psexec.cmd (code below). However, if a file takes too long to process, I get the error message that the temp file is still being used by the process (temp file is still being written)
I figured out a way to detect when the file is no longer in use. But then to my horror.. I realized I AM GET THE SAME DAMN ERROR I did using the System Internals utility!!!ERROR: Input redirection is not supported, exiting the process immediately.
aGerman, could you please help me to avoid that error. I don't even know exactly why it's happening. I just want a reasonable solution to return the output of a command I execute on a remote machine; even if the output takes several seconds to finish.
Code for PSexec.cmd
usage syntax Examples:
\\servername command arg arg arg
servername command blah blah blah
