echo "hi" > /dev/console will work but your should note that most error messages do not use stdout but rather stderr so when you start your script you should really do something like this:

myscript > /dev/console 2>&1

You are correct Sir.

Try it. It won't hurt anything.

Hi .. thanks !!!

with this line:
myscript > /dev/console 2>&1

i can't understand: 2>&1

Hi Manuales:

# myscript > /dev/console 2>&1

...says to redirect the standard output (STDOUT or file descriptor #1) of 'myscript' to /dev/console. Then, to that, duplicate the output of standard error (STDERR or file descriptor #2) to whatever STDOUT points.

See the manpages for 'sh-posix' in the section titled "Input/Output" for more information.

then ... with next line:
myscript > /dev/console 2>&1

i can see all messages of script executed in /dev/console as much messages as errors?

thanks, Manuales.

Hi Manuales:

Yes. As Clay noted, good software writes error and warning messages to STDERR and its other output to STDOUT. The redirection shown pushes *both* those streams to the same place --- the console in this case.

Hi Manuales ,

Its redirecting , stdout and stderr together with ">&"

2>&1 is :

2 for standard error. stderr.
1 for standard output. stdout.

Cheers,
Raj.
