hey guys, this was kind of interesting so I thought I might report it to anyone who might take an interest in this thread. But I just realized where the 'additional' percentage that the tablespace check is reporting comes from.
It comes from the fact that the check is attempting to report two tablespaces and that's why the formatting is falling apart. I altered the print statement of the loop a little bit and saw the important difference: while i=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $1}') j=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $3}') k=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $2}') l=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $4}') do TBLSPACE=$i PCT=$j FREE=$k TOTAL=$l if [ "$TBLSPACE" ] then echo "NOK" $TBLSPACE " is at " $PCT $FREE/$TOTAL exit 2 else echo "All OK" exit 0 fi done Now outputs: [db07-dc2:~] root% /opt/nagios/libexec/check_qaecom1_tablespace.sh NOK BAM_USER_INDX_LG MLBDATASM is at 97.50% 95.85% 820 340/32764 8191 So what I need to try and figure out is how to print additional tablespaces that meet the threshold levels and have the output make sense visually. I will keep working on this, but would welcome any input you might have.

This is probably more of a bash programming issue, but as the ultimate purpose of the script is to be a nagios check I am hoping that you won't mind me asking here. Just to give you a brief overview of what I am experiencing, I'd like to start by giving you the output of a couple runs of the script and a couple snippets of code. First: [db07-dc2:~] root% /opt/nagios/libexec/check_qaecom1_tablespace.sh /opt/nagios/libexec/check_qaecom1_tablespace.sh: line 60: [: BAM_USER_INDX_LG: unary operator expected All OK is mainly achieved through this loop: while i=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $1}') j=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $3}') k=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $2}') l=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $4}') do TBLSPACE=$i PCT=$j FREE=$k TOTAL=$l if [ $TBLSPACE ] then echo "NOK $TBLSPACE is at $PCT $FREE/$TOTAL " exit 2 else echo "All OK" exit 0 fi done But as you can see a 'unary operator' error is produced by this code. As you can probably tell, all it does is execute a few sqlplus commands (with the SQL contained in a separate file) and assign them to a few variables. It incorrectly produces an 'OK' state. But if I try to fix the 'unary operator' error by putting the TBLSPACE variable in quotes, the result changes from "ALL OK" to showing some output and (correctly) produces an error state: [db07-dc2:~] root% /opt/nagios/libexec/check_qaecom1_tablespace.sh NOK BAM_USER_INDX_LG MLBDATASM is at 97.50% 95.85% 820 340/32764 8191 while i=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $1}') j=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $3}') k=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $2}') l=$($sqlplus -s -l $USERNAME/$PASS@$SID @/opt/bin/ops/mlb_tablespace.sql | awk '{print $4}') do TBLSPACE=$i PCT=$j FREE=$k TOTAL=$l if [ "$TBLSPACE" ] then echo "NOK $TBLSPACE is at $PCT $FREE/$TOTAL " exit 2 else echo "All OK" exit 0 fi done The SQL is designed to list any tablespaces that grow beyond a certain threshold. My question is this: [db07-dc2:~] root% /opt/nagios/libexec/check_qaecom1_tablespace.sh NOK BAM_USER_INDX_LG # <-- this is correctly output from the script MLBDATASM is at 97.50% # <-- this is also correctly output from the scipt 95.85% 820 # <-- but where does this additional and different percentage come from? 340/32764 # <-- and why are the two variables $FREE/$TOTAL broken up on different lines? 8191 I realize that this may not be an easy question, but I wanted to put this out there in case anyone has faced a similar situation before.
