Determine name of installed package
How does one determine the command name of an installed package?
For instance, after installing the below, I would have expected it to be
nmap-ncat , but it is really
ncat or
nc .
Thanks
Code:
[michael@box1 ~]$ sudo yum install nmap-ncat.x86_64

there is no such thing. I mean for example the base package contains a lot of commands. Others contain a toolset, and finally the creator of the package can give any name (s)he wants.

https://linux.die.net/man/1/nc
https://nmap.org/ncat/
You can always google...

You risk opening a hole on your system fiddling around with programs you don't understand like netcat.

I think it might suffice to say not to use netcat over the public Internet.

It would suffice, I only told them why it's not a good idea.

Never, or not until the program is understood? Any specific vulnerabilities one should be on the lookout for? Thanks

I was referring to opening ports. Ports you might not be aware you're opening that someone could access and looking out for your best interest.
If I were you I would study docs thoroughly to become familiar with its many functions before using it.
In addition to the Users Guide I linked to, where they reference it as "your network Swiss Army knife", there are several articles online about its use. This is just one:
