[Message part 1 (text/plain, inline)]

I am not sure if this is a bug or not. Her is an example of my script that
I am running.

#!/bin/bash

rm -f x.txt
rm -f new_file

i=1
wc -l file1 | sed 's/file1//g' >> x.txt

x=$(<x.txt)

while [ $i -le $x ]
do
            #echo "$i"
         A=$( awk -v var="$i" 'NR==var {print}' file1)
        #ack -k file1 file2 --match $A >> new_file
        grep $A some_file.txt
    ((i++))

done

grep does not appear to be grepping inside of the while loop. When I
initialize a variable directly from the command line and write the same
script it works no problem, any help on this matter would be greatly
appreciated.
