Hi all, I want to input a string which is used to create file name, and I want to allow input string to consist of letters(SDK) at the start and only IR and DEV inbetween, and numbers(0-9) and underscore( _ ) within file name. Is the pattern right. m/^SDK[0-9]|^SDK_[0-9]|^SDK_[0-9]_IR|^SDK_[0-9]_IR_DEV$/
if ($input =~ /what pattern /){
create file
} else {
exit 0; }
Regards
