Hi,

Is there any command in unix similar to spool command in oracle.

2

If you consider SPOOL command causes SQL*Plus to write the results to a file.

SQL> spool /tmp/output.lst

In UNIX send the result (output) of ls to a file would be

    $ ls >/tmp/output.txt

But I wonder if you are not thinking of something else like script
do a man of script command and see if thats not your answer

vbe,

ls >/tmp/output.txt
man ls >/tmp/output.txt

from the above line 1, it will redirect the ls o/p to the file /tmp/output.txt.
second line also do the same as redirect the o/p to the file /tmp/output.txt.

for each time i need to provide the redirection to file.
whereas in Oracle, Spool command will write the results to a file untill i provide spool off.

is there any command equalient to spool in unix ???

No.

You can do:

./script >file 2>&1

Yes. Use redirection. At the top of your script, put:

exec 1>/tmp/output.txt

Thanx,

As per suggestion its working fine but it re-directing everthing to a file. i need to display the results also in the screen.

For eg: File.sh

exec 1>/tmp/output.txt
ls -ltr
exit

when i run this script, its redirect to a file /tmp/output.txt but it not displaying in the screen. what needs to do ?

I had found the answer for this. there is an command called script in unix which will make record of a terminal session (like spool does in oracle). to stop the spooling type exit.
