Oracle's sqlplus has a rich set of commands that can format your results in a large number of ways, thereby rendering "sed" or "grep" or "egrep" useless.

If you use these sqlplus commands, you don't have to do extraneous processing using Unix utilities. And you don't have to create and remove temporary files either.

Here's a short script that illustrates their usage:

Code:
test@ORA11G>
test@ORA11G> -- The data in my Oracle table looks like this
test@ORA11G> select * from t;
         X Y Z         W
---------- - --------- ----------------------------------------------------------------------------------------------------
         1 a 19-SEP-08 the quick brown fox
         2 b 19-OCT-08 @#$ jumps over the ::
         3 c 19-NOV-08 lazy dog...
         4 d 19-DEC-08 abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789~!@#$%^&*()_+{}|:"<>?`-=[]\;',./
4 rows selected.
test@ORA11G>
test@ORA11G>

And here's the Bash shell script and its execution:

Code:
$
$ # display the content of the shell script
$ cat tst.sh
#!/usr/bin/bash
sqlplus -s test/test <<EOF >outfile.log
SET NEWPAGE NONE
SET LINESIZE 9999
SET TRIMSPOOL ON
SET FEEDBACK OFF
SET VERIFY OFF
SET UNDERLINE OFF
SET COLSEP ","
select * from t;
exit
EOF
$
$ # source the shell script
$ . tst.sh
$
$ # check the generated flat file
$ cat outfile.log
         X,Y,Z        ,W
         1,a,19-SEP-08,the quick brown fox
         2,b,19-OCT-08,@#$ jumps over the ::
         3,c,19-NOV-08,lazy dog...
         4,d,19-DEC-08,abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789~!@#$%^&*()_+{}|:"<>?`-=[]\;',./
