I want to remove ^@ from the end,only if it gets appended to $str. 
$str="himanshu.txt^@";
if($str =~ /(\w+)/) {
    $str = "$1.$2";
}

This is working well.So I am getting $str="himanshu.txt" Now second case.If I am having cases like $str="himanshu-prg.txt^@" or $str="hel_llo-workd.txt^@"What will the regular expression? CONCLUSION possible patterns; $str= <combination of words,number,dash> . txt (somtimes ^@ gets appended,so i want to sense that and remove)
