How to validate user's input..?
Code:
$Input_filename=$ARGV[0];
if (!-d $Input_filename && ! -e $Input_filename)
{
print "USAGE: Please enter '$ABCD/def/dsed.txt' as an arguement \n";
exit;
}1. Input Is suppose to be something like "$ABCD/def/dsed.txt". if the input is wrong the script should throw an ERROR message. if user enters $ABCD only, error message should be displayed. if the user enters "$ABCD/def/" a error message shold be displayed. do i need any regex to check it out?? PLEASE SUGGEST..... |
