I have a hash whose values are an array of file contents.I am trying to get a for loop going for each line the value as below.For some reason the for loop is not entered.When I debugged,the array value is like below.Can someone advise what am I doing worng? 

@{$grep_lines{$filename}}= ARRAY(0x...)

my %grep_lines;

foreach $mk(@{ $grep_lines{ $filename } })
             {
#doesnt enter the loop
}
