Hi Ahamed..
I thnk there is some syntax problem with this..It is throwing syntax error while running:
Code:
awk ' { if ( $2 ~ "[^a-zA-Z]" ) {print $1,substr($3,length($3),1)}}' ./output.txt | while read a b
do
echo $a
echo $b 
done

output is :
Code:
awk: syntax error near line 1
awk: illegal statement near line 1
awk: syntax error near line 1
awk: bailing out near line 1

Yeah it worked...Thankyou verymuch for the quick responseSmilie
I have one more doubt..
Iam running a sql select command inside shell script and redirecting its output to a file.
is there any way to wait until the query completes (like wait command) its processing and redirecting the output to the file.
Because the code is trying to access the file before the query completion and am getting ambigous errors because of it>
Am pasting here the code for your reference.
Please provide me a way to get rid of this problem
Code:
sqlplus -s /nolog |&
print -p "connect $db_user/$db_pwd@$db_sid;"
print -p "SPOOL output.txt;"
while read var_ack_party_name
do
print -p "set pagesize 0 feedback off verify off heading off echo off linesize 100 \n"
print -p "select *  from bus_event where ack_party_name like 'MOVE_USAGE_DAEMON%' and event_data_text like '%"$var_ack_party_name"%';"
done <./$1.txt

nawk '{if($2 ~ "^[a-zA-Z]"){print $1,substr($3,length($3),1)}}'  ./output.txt | while read a b
