Redirect STDOUT Stream for Command to File
How to redirect STDOUT stream from the screen to a file? I want the command to send output data to a file.
By default, the STDOUT stream for a command is mapped the screen. If the command is writing data to the STDIN stream, you will see it on the screen.
But, you can use the ">" redirect operator to redirect the STDOUT stream from the screen to a file as shown below:
command options > file-name
For example, the "DIR" command writes a list of files and sub-directories to the STDOUT stream. By default, "DIR" writes the list to the screen. But you can redirect it to a file as shown below:
C:\fyicenter>dir \windows\System32\spool > dir.txt
Now the file dir.txt contains the output of the "DIR" command. If you open it in notepad, you see the following:
Directory of C:\windows\System32\spool 12/13/2016 11:15 AM DIR . 12/13/2016 11:15 AM DIR .. 07/13/2009 11:57 PM DIR drivers 12/12/2017 07:50 PM DIR PRINTERS 07/13/2009 10:20 PM DIR prtprocs 12/13/2016 11:14 AM DIR SERVERS 12/12/2017 09:51 AM DIR tools 0 File(s) 0 bytes
Note that the "> file-name" direction will replace old content of the file, if it is an existing file.
