Oracle-L: RE: Unix Q: ksh scripting

It works for me. Using the following code:

#!/bin/ksh
#set -x
sqlplus / <<EOF | tail -1
select sysdate from dual;
exit
EOF I get:

$ test.sh
JServer Release 8.1.7.0.0 - Production
$

With -x flag set:

$ test.sh

+ tail -1
+ sqlplus nri/nri
+ 0< /tmp/sh27884.2

JServer Release 8.1.7.0.0 - Production
$

As previously mentioned, to get the last row of the actual output you need to use the '-s' flag, move the pipe to the command line and get rid of the blank lines:

#!/bin/ksh
set -x
sqlplus -s / <<EOF | grep -v ^$ | sed -n '$p' select sysdate from dual;
exit
EOF $ test.sh

+ sqlplus -s /
+ sed -n $p
+ grep -v ^$
+ 0< /tmp/sh28234.2

24.07.2002
$

or - without the -x flag (which I presume is the desired result):

$ test.sh
24.07.2002
$

Hmm, this still doesn't seem to work.

Oops, missed a quotation mark in earlier posting. Should have read:

sqlplus -s / << EOF | grep -v ^$ | sed -n '$p' select sysdate from dual;
exit
EOF Regards

Ross,

You are hitting a couple of problems here:

1 - the 'tail' command needs to be on your first line (sqlplus / <<EOF | tail -1)

2. However, I suspect this will not give you what you want as sqlplus prints a blank line at the end. Try the following:

sqlplus -s / << EOF | grep -v ^$ | sed -n '$p select sysdate from dual;
exit
EOF Grep will remove blank lines - sed will print last line. I'm sure there are many more ways of doing this.

HTH, Chris

Hi all,
Can any of our Unix gurus here transform my script below to work properly? The intention is to print the last line of the sqlplus output. With set -x, it appears anything after the last EOF is ignored. Why? Thanks.
Ross

#!/bin/ksh
#set -x
sqlplus / <<EOF
select sysdate from dual;
exit
EOF | tail -1
