Hi,
Can anyone help me to find regular expression for the following in Perl?
"The string can only contain lower case letters (a-z) and no more than one of any letter."
For example: "table" is accepted, whether "dude" is not.
I have coded like this:
$str = "table";
if ($str =~ m/\b()\b/) {... (4 Replies)

mdns-scan
MDNS-SCAN(1) General Commands Manual MDNS-SCAN(1) NAME
mdns-scan - Scan for mDNS/DNS-SD services published on the local network SYNOPSIS
mdns-scan DESCRIPTION
mdns-scan is a tool for scanning for mDNS/DNS-SD published services on the local network. It issues a mDNS PTR query to the special RR _services._dns-sd._udp.local for retrieving a list of all currently registered services on the local link. OPTIONS
mdns-scan has no commandline options. NOTES
mdns-scan is not a good mDNS citizen since it queries continuously for services and doesn't implement features like Duplicate Suppression. It is intended for usage as a debugging tool only. mdns-scan is incomplete since it doesn't resolve mDNS services for you - it just dumps their PTR RRs. To understand these records you need minimal knowledge of DNS-SD and how it works. mdns-scan does not terminate on its own behalf. It scans for services continuously until the user kills it by pressing C-c. mdns-scan does not rely on a local mDNS responder daemon. It has no dependencies besides the GNU libc. It has been tested on Linux only. mdns-scan does NOT scan for local mDNS enabled hosts or A/AAAA RRs, it scans for DNS-SD registered services, nothing else. SEE ALSO
