Re^4: user input file

I am working on Padre , here the script has been written so I wish that user should input the file name on command prompt , when we run it . In padre we have an option to run the script , which gives a cmd with result on it , we can also give inputs from cmd as well

If you want the user to type the file name into the interactive terminal that Padre spawns, then you should assign the file name from STDIN - see I/O Operators in perlop. That code will probably look like: `my $filename = <>; chomp $filename; open(FILE,"<", $filename) or die "Open failed for $filename: $!"; + my @lines=<FILE>;` [download] The chomp is necessary because your input will have a trailing newline which is not in the file name. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l]

    my $filename = <>;
    chomp $filename;
    open(FILE,"<", $filename) or die "Open failed for $filename: $!"; 
+          
    my @lines=<FILE>;
