How to redirect console output to file and STILL get it in the console?

Question

I want to run an ANT script which prompts the user for input, so it needs to be interactive through the console. at the same time I want to log the console content to a log file

Answer 1

Use tee.

ant 2>&1|tee build.log

tee.exe is also available for Windows from http://unxutils.sourceforge.net/

Answer 2

You can use tee.

Example:

$ echo "Hello, world" | tee /tmp/outfile
Hello, world
$ cat /tmp/outfile
Hello, world

tee writes its stdin to both stdout as well as one or more files given on the command line.
