Questions related to if in awk context and if without awk context
I wrote this code, questions follow


Code:
#! /bin/bash -f 

 # Purpose - to show how if syntax is used within an awk
  clear;
  ls -l;

  echo "This will print out the first two columns of the inputted file in this directory";
  echo "Enter filename found in this directory";
  read input;
  awk '{if($input == echo$(ls)) 
         {
          print $1 "\t" $2;
         }
         else
          {
          echo "file " $input " not in this Directory";
          exit
          }
       }' $input


Question 1 - how would I write this better so that my commands are executed under the else statement instead of getting a fatal error when $input is not a file in the Directory?


Question 2 - how would I represent this if statement outside this script and not within an awk command? When using if [ $input == echo$(ls) ] or if [[ $input == echo$(ls) ]]
where $input is a file name in the Directory I get a "too many arguments" and false return or just a false return respectively.



Thank you in advance.
