bash loop processing all files in a directory

I have this script 

$AIRLINECODE=xx
for i in $AIRLINECODE_response_*; do
  echo $i
done

prints all the files in the directory even if they have a completely different name..

what can i do to limit the for to find only the files that have the wished pattern?

This is because of how you are using the variable name.

When you use $AIRLINECODE_response_, bash interprets it as AIRLINECODE_response_ being the name of the variable. To make it work, use curly braces to specify what is the name: {AIRLINECODE}_response_.

All together:

AIRLINECODE=xx
for i in ${AIRLINECODE}_response_*; do
  echo "$i"
done

Also, note that you need to set the variable with AIRLINECODE=xx. It is wrong to use $AIRLINECODE=xx, because the variables are being set without the leading $.
