Value not getting printed outside loop
Hi all I'm using below code
Code:
#!/bin/bash
export fileclob
cd /home/appsuser/dataload
file='EG.mdd'
chmod 777 $file
dos2unix -ascii -k -q -o  $file $file
sed -e '${/^$/d}' $file
cat $file | while read LINE
do
  echo "line is"
  if [ -n $LINE ]
  then
  echo "line is $LINE"
  echo " "
  Y=${#fileclob}
  if [ $Y = 0 ]
  then
    fileclob=$LINE
     echo  "fileclob_1 $filecloob"
  else
    fileclob="${fileclob},${LINE}"
    echo  "fileclob_2  $fileclob"
  fi
 fi
done

echo "${fileclob} "
sqlplus apps/apps <<EOF
set pagesize 0 feedback off verify off heading off echo off serveroutput on
insert into lshadmin.global_table (file_name,study_name,table_struct)
  values('EG','MK898','$fileclob);
commit;
exit;
EOF

when I try to print the value ${fileclob} outside the loop it is coming null but within the loop it is printing correctly.
There is no blank line at end of file.

Pls help.

Use:
Code:
while read LINE
do
  echo "line is"
  if [ -n $LINE ]
  then
  echo "line is $LINE"
  echo " "
  Y=${#fileclob}
  if [ $Y = 0 ]
  then
    fileclob=$LINE
     echo  "fileclob_1 $filecloob"
  else
    fileclob="${fileclob},${LINE}"
    echo  "fileclob_2  $fileclob"
  fi
 fi
done<$file

Instead of:
Code:
cat $file | while read LINE
do
  echo "line is"
  if [ -n $LINE ]
  then
  echo "line is $LINE"
  echo " "
  Y=${#fileclob}
  if [ $Y = 0 ]
  then
    fileclob=$LINE
     echo  "fileclob_1 $filecloob"
  else
    fileclob="${fileclob},${LINE}"
    echo  "fileclob_2  $fileclob"
  fi
 fi
done

do not pass '$file' through 'cat', change the while block to below and it will work
Code:
while read LINE
do
.
.
.
done < $file

Below is the test
Code:
$ echo ${var1}
$ cat sam | while read line
> do
> var1=$line
> done
$ echo ${var1}
$ echo ${var2}
$ while read line
> do
> var2=$line
> done < sam
$ echo ${var2}

I changed it to:
Code:
#!/bin/bash
export fileclob
cd /home/appsuser/dataload
file='EG.mdd'
chmod 777 $file
dos2unix -ascii -k -q -o  $file $file
sed -e '${/^$/d}' $file
 while read LINE
do
  if [ -n $LINE ]
  then
  echo "line is $LINE"
  echo " "
  Y=${#fileclob}
  if [ $Y = 0 ]
  then
    fileclob=$LINE
     echo  "fileclob_1 $fileclob"
  else
    fileclob="${fileclob},${LINE}"
    echo  "fileclob_2  $fileclob"
  fi
 fi
done < $file
echo "file is ${fileclob} "
sqlplus apps/apps <<EOF
set pagesize 0 feedback off verify off heading off echo off serveroutput on
insert into lshadmin.global_table (file_name,study_name,table_struct)
  values('EG','MK898','$file');
commit;
exit;
EOF

echo "file is ${fileclob} " whole statement is not visible after executing the script

try
Code:
for LINE in $(cat $file)

instead of
Code:
cat $file | while read LINE

in your orignal script
