Hi,
I used to use netcat to check if a particular host is up or if I have internet connection before I run a few scripts. I would use the -z option in particular. But now I see that has been removed:
$ nc -z imap.gmail.com 993 && sync-my-email.sh ncat: invalid option -- 'z'
Here is the excerpt from the old manual page:
-z Specifies that nc should just scan for listening daemons, without sending any data to them. It is an error to use this option in conjunction with the -l option.
Any ideas what happened to it? What can I use as replacement?
Thanks for any ideas.
