Plink command results not being saved to local text file

问题

I am calling a remote ssh through PuTTY's Plink functionality - I am able to connect and run my commands but not able to store Output into another text file - my script is as:

plink ssh_hostname -m "directory\till\inputCommand.txt" -l username -pw password > "directory\where\OutputTxt_Will_Be_Saved\OutputRes.txt"

Here OutputRes.txt is created, but it is completely blank. The result is shown on the command line, but not saved into OutputRes.txt (that's what I want to save on).

回答1:

The command probably prints its output to an error output stream, not standard output stream.

To capture the error stream, add 2> redirection:

plink ... 2> "directory\where\OutputTxt_Will_Be_Saved\ErrorRes.txt"

To capture both standard and error outputs to the same file, use 2>&1:

plink ... > "directory\where\OutputTxt_Will_Be_Saved\OutputRes.txt" 2>&1

See Using command redirection operators.
