How to hide terminal output in Linux [message #260527]

Hello All,
Here is another query regarding the database health check shell script I'm writing.
Actually, in the script I'm redirecting the output to a file(temp) as :

sqlplus -s $usnm/$passw@$ORACLE_SID >> temp << EOF

The script works fine unless I turn to get the chained rows count.
In this shell script,I've spooled a sqlscript so as to analyze the tables to list the chained rows
& then have make it run immediately as -

set feedb off
spool anlz.sql

select 'analyze table '||owner ||'.'||table_name||' list chained rows;'
from all_tables;
spool off;

@/home/test/anlz.sql

Now the problem is, the output of the spooled sql file appears as a terminal output giving the feedback of the analyze commands executed.
Do anyone has idea how can I hide the output from terminal?
(It redirects all the output in the 'temp' file as well)

Thanks in advance.

Thanks Sir,
Actually, forgot to mention I had tried doing that but still I'm getting the whole command statement as :-

analyze table SYS.LOGMNRG_CCOL$ list chained rows;

as well as,the feedback

table analyzed;

Note : Well, by mistake the sys object analyze statement is posted. Actually I have ommitted the sys and other default user tables from analyzing

Using such a file you'll get file full of ANALYZE TABLE statements which will also get executed at once:

REM analyze_prep.sql

set heading off
set feedback off
set termout off
spool analyze.sql

select 'analyze table ' || tname || ' estimate statistics;'
from tab
where tabtype = 'TABLE';

spool off;

@analyze.sql

This is how 'analyze.sql' looks like:

REM analyze.sql

analyze table PLAN_TABLE estimate statistics;                            
analyze table TOAD_PLAN_TABLE estimate statistics;                              
analyze table DEPT estimate statistics;                                         
analyze table EMP estimate statistics;                                          
analyze table BONUS estimate statistics;                                        
analyze table DUMMY estimate statistics;

And this is how execution looks like; as you can see, there's nothing there, actually:

SQL> @analyze_prep
SQL>

Thats how exactly the things are ( check out my problem statement )

set feedb off
spool anlz.sql

select 'analyze table '||owner ||'.'||table_name||' list chained rows;'
from all_tables;
spool off;

@/home/test/anlz.sql

This is whats I'm doing. But thing is that, I'm writing all this in Linux shell script & all the matter which should reflect only in the spooled file (anlz.sql) i. e.

analyze table user.PLAN_TABLE list chained rows;

is reflecting on the linux terminal as well as in the file.
As if this isn't enough, even the feedback for it

i.e. table analyzed;
is out on the terminal even after setting the feedb off.
Just wonder what can be done!

You have this           I have this
-------------           -----------------
set feedb off           set heading off
                        set feedback off
                        set termout off

I guess you see the difference. Now, I don't say that it is the solution, but - did you, at least, try it?

Yeah, I have tried it out. Actually, its just was part which I posted. But still, I'm getting the expected output.
Is there any possibility to hind this by using Linux command? or by setting any Linux parameter?
I do agree, it's the SQL output, but to control it's display on OS terminal might be somewhere an OS issue! It's just a guess. what do u think?

I think the following:

Quote:

set feedb off
spool anlz.sql

select 'analyze table '||owner ||'.'||table_name||' list chained rows;'
from all_tables;
spool off;

@/home/test/anlz.sql

Is in your shell script.
You have to put it in a SQL script to don't see it in your output.

U caught it, right!
I was doing the same.. n now THANKS.. It worked.
It's taking a few more seconds probably as it has to go through some more scripts and then execute, but surely has solved the purpose.
Thanks again!

Well, if you had carefully reviewed my post with sample scripts, you'd see REMarks containing every script name - those were SQL's, not shell scripts.

Well,I respect the solution posted by u.
Let me clarify :

Have a look at part of my shell script :

sqlplus -s $usnm/$passw@$ORACLE_SID >> temp << EOF
SET heading off;
SET termout off;
SET feedback off;
SET linesize 90;

spool anlz.sql

select 'analyze table '||owner ||'.'||table_name||' list chained rows;'
from all_tables;
spool off;

@/home/test/anlz.sql

SELECT ' Database Health Check Report ' from dual;
SELECT 'Instance Name :', instance_name FROM v\$instance;

SELECT 'Version :',banner
FROM v\$version
WHERE banner LIKE '%Oracle%';
.
.
.
.
.
.
..
.

likewise.

Actually I was writing the SQL script only, but in the shell script.
Now see what I've done with the same script.

I took,

Toggle Spoiler

this code into a SQL script as anlzsrpt.sql

and then called that in my original script as follows:

Toggle Spoiler

Actually the whole procedure is taking lot of time but at least purpose is solved.
