Shell Programming and Scripting

Please put code inside [code] tags.

 
  while read Record1
do
 Acct_Num=`echo $Record1 | awk '{print $2 }'`
 ID=`echo $Record1 | awk '{print substr($Acct_Num, 1, 3 ) }`

The immediate problem is that a shell variable is not expanded inside single quotes. You can pass a variable to awk with -v:

Code:

awk -v Acct_Num="$Acct_Num" '{print substr(Acct_Num, 1, 3 ) }'

The other problem is that your script will run excruciatingly slowly because you are calling awk twice for every line of the file.

Instead of using a shell loop, let awk do all the work:

Code:

awk '{
  printf "AcctNum is %s\n", $2
  printf "ID is %s\n", substr($2,1,3)
   }' "$REGSeqFileName"
