Hi guys in the screen shot that guy used a command



./test.shh 2>&1 |tee test.log


what's the use of 2>&1 and why he has to use that ??

[steeldriver]

2>&1redirects the standard error stream (stream 2) into the standard output stream (stream 1) - so error messages get combined with any other output from the command

A little Googling gave me this:

Basically, 2>&1 means "redirect all output from stderr to stdout".
EDIT: Ninja'd!
