the issue is as you posted the code for the previous problem in thread "giving same name to two files " . If the first time input is correct then it works fine , but if the user gives wrong file name , so I am doing this
while (!-e $filename)
print STDERR "\n$filename not found. \n Ensure that you have
+ given the correct file name\n and the file exists in the working dir
print "Re-enter filename, or q to quit: ";
$filename = <STDIN>;
# my @filenam = split ('\.', $filename);
exit() if $filename eq "q";
the commented line is what I have added , so it takes only the first time name ,not the correct one .
