Redirect STDOUT Stream to the End of File
How to redirect STDOUT stream from the screen to the end of a file? I want to append output from STDOUT stream to an existing file.

When using the ">" redirection to an existing file,
old content of the file will be replaced.
You can keep the old content of the file by using the append redirection operator ">>" as shown below:
command options >> file-name
For example, the "echo %random%" command generates a random number and writes to the STDOUT stream. By default, "echo" writes the random number to the screen. But you can redirect it to the end of a file as shown below:
C:\fyicenter>echo %random% >> list.txt C:\fyicenter>echo %random% >> list.txt C:\fyicenter>echo %random% >> list.txt C:\fyicenter>echo %random% >> list.txt C:\fyicenter>echo %random% >> list.txt
Now the file list.txt contains 5 random numbers. If you open it in notepad, you see the following:
29435 9430 13532 18297 27977
