I wrote a simple code (part of the entire code) to parse a file. Each line is parsed in a loop over here.

but when i run this script, i get an error that done unexpected??? if i remove that (shouldnt though) then i get error _EOF1_ not found.

am i missing some rules over here

Code:

command=`cat << _EOF1_ 
cat $DATA_FILE|while read LINE
 do
    var1=`echo $LINE | awk -F"|" '{print$1}'`
    var2=`echo $LINE | awk -F"|" '{print$2}'`
    var3=`echo $LINE | awk -F"|" '{print$3}'`
    var4=`echo $LINE | awk -F"|" '{print$4}'`
    var5=`echo $LINE | awk -F"|" '{print$5}'`
    var6=`echo $LINE | awk -F"|" '{print$6}'`
    var7=`echo $LINE | awk -F"|" '{print$7}'`
    var8=`echo $LINE | awk -F"|" '{print$8}'`
    var9=`echo $LINE | awk -F"|" '{print$9}'`
    var10=`echo $LINE | awk -F"|" '{print$10}'`
    var11=`echo $LINE | awk -F"|" '{print$11}'`
done
_EOF1_`

What are you trying to accomplish with the command= and EOF stuff?

Running the code just as:

Code:

cat $DATA_FILE|while read LINE
 do
    var1=`echo $LINE | awk -F"|" '{print$1}'`
    var2=`echo $LINE | awk -F"|" '{print$2}'`
    var3=`echo $LINE | awk -F"|" '{print$3}'`
    var4=`echo $LINE | awk -F"|" '{print$4}'`
    var5=`echo $LINE | awk -F"|" '{print$5}'`
    var6=`echo $LINE | awk -F"|" '{print$6}'`
    var7=`echo $LINE | awk -F"|" '{print$7}'`
    var8=`echo $LINE | awk -F"|" '{print$8}'`
    var9=`echo $LINE | awk -F"|" '{print$9}'`
    var10=`echo $LINE | awk -F"|" '{print$10}'`
    var11=`echo $LINE | awk -F"|" '{print$11}'`
done

Would make the loop work successfully (assuming you had $DATA_FILE previously defined in your shell or the script).

If you are trying to define a command to be used elsewhere within the script just do a man on bash and have a look at the "function" description.

Your logic is not clear.

Code:

command=`cat $DATA_FILE|while read LINE
 do
    var1=`echo $LINE | awk -F"|" '{print$1}'`
    var2=`echo $LINE | awk -F"|" '{print$2}'`
    var3=`echo $LINE | awk -F"|" '{print$3}'`
    var4=`echo $LINE | awk -F"|" '{print$4}'`
    var5=`echo $LINE | awk -F"|" '{print$5}'`
    var6=`echo $LINE | awk -F"|" '{print$6}'`
    var7=`echo $LINE | awk -F"|" '{print$7}'`
    var8=`echo $LINE | awk -F"|" '{print$8}'`
    var9=`echo $LINE | awk -F"|" '{print$9}'`
    var10=`echo $LINE | awk -F"|" '{print$10}'`
    var11=`echo $LINE | awk -F"|" '{print$11}'`
done`

What might be a better question- what are you trying to do? When this completes $command will be empty unless you've redirected stderr

I gave only part of the code to avoid confusion but on contrary it has created more confusion.

Code:

command=`cat << _EOF1_ 
cat $DATA_FILE|while read LINE
 do
    var1=`echo $LINE | awk -F"|" '{print$1}'`
    var2=`echo $LINE | awk -F"|" '{print$2}'`
    var3=`echo $LINE | awk -F"|" '{print$3}'`
    var4=`echo $LINE | awk -F"|" '{print$4}'`
    var5=`echo $LINE | awk -F"|" '{print$5}'`
    var6=`echo $LINE | awk -F"|" '{print$6}'`
    var7=`echo $LINE | awk -F"|" '{print$7}'`
    var8=`echo $LINE | awk -F"|" '{print$8}'`
    var9=`echo $LINE | awk -F"|" '{print$9}'`
    var10=`echo $LINE | awk -F"|" '{print$10}'`
    var11=`echo $LINE | awk -F"|" '{print$11}'`
    ##example of statement which i plan to use
    SQL=`echo select ${var1} from ${var11}`
    ${SQL}
done
_EOF1_`

and then next from a interactive program i want to call ${command}

You reinvented the concept of a function.

Try this instead:

Code:

command1 () {
  #
  # What follows here, was pasted from jlightner's post.
  #
  cat $DATA_FILE|while read LINE
   do
      var1=`echo $LINE | awk -F"|" '{print$1}'`
      var2=`echo $LINE | awk -F"|" '{print$2}'`
      var3=`echo $LINE | awk -F"|" '{print$3}'`
      var4=`echo $LINE | awk -F"|" '{print$4}'`
      var5=`echo $LINE | awk -F"|" '{print$5}'`
      var6=`echo $LINE | awk -F"|" '{print$6}'`
      var7=`echo $LINE | awk -F"|" '{print$7}'`
      var8=`echo $LINE | awk -F"|" '{print$8}'`
      var9=`echo $LINE | awk -F"|" '{print$9}'`
      var10=`echo $LINE | awk -F"|" '{print$10}'`
      var11=`echo $LINE | awk -F"|" '{print$11}'`
  done
}

After doing

Code:

bash$ source /path/to/the/script.sh

you can just do:

Code:

bash$ command1
