Redirecting output to a file and terminal

[Bala_4]

Hi All

I would like to redirect the output to the terminal and a file and the error to the error file. This is what I was trying. But the output is never displayed on the screen.

echo "abcd" > aa 2>&1

I want simultaneously the output to be stored in the file and displayed on the terminal.
I am using ksh

Thanks in advance
Bala

Bala:

Try the following:

# echo "abcd" | tee -a out_file 2>&1

-EH

Bala,

You could try the "script" command which would direct all your terminal output to a file without hiding it.

eg.

script outfile.txt

script off

cat outfile.txt

try this:

echo "abcd" | tee aa 2>&1

Hi Bala,

I didn't test what the other authors proposed to do. Here is what I found how to get what you want:

(date;date -x) 2> buf2 | tee buf

'buf2' contains stderr while stdout appears on the terminal and is written to 'buf'. See the man page of tee for some options.

In echo "abcd" > aa 2>&1 you replace ">" with
|tee -a (-a for append).You can see man tee.

try this:

===============
$ echo err | tee -a errfile 2>&1
err
$ echo err2 | tee -a errfile 2>&1
err2
$ cat errfile
err
err2
$
