Redirection Problem

I was simply trying to redirect some output in a log file but it foxed me.

truss a.out > log

It gave only the output of the a.out which was only a simple print "Hello"

Then I tried

truss a.out 2&1>a
echo `truss a.out` > a

All failed.

What am i missing.
Thanks

Phew,

So simpleeeeeeeeeeeeeeeeeeeee

By the way, can you explain this to me.

Check out man bash under the title

Redirecting Standard Output and Standard Error

Basically it says, redirect standard output and standard error to output.

Another way to do it (and also find the answer to the original redirection question....)

man truss

-o outfile
           File to be used for the trace output. By default,  the
           output goes to standard error.

Later on when i realised what i was doing with a cool mind, I was laughing on myself.

I knew it, but sometimes :stuck_out_tongue:

On a much much lighter note, (quoting from the movie Serendipity)

If you want to improve, be content to be thought foolish and stupid.

Cheers' & Good times ahead !
