I've recently switched from Linux to Mac OS X and I'm trying to get used to the new environment. One of the differences from Linux is the way to find the process id (pid) listening on a specific port. In Linux you do like this:
to show the pid listening on port 8080. On Max OS X how ever you'll run into the following error message:
PIV Login for Macs is an ongoing initiative to implement the federally mandated smart card login requirement on Apple Macintosh computers at NIH. The PID is always a number, and every single process running on a Mac has an associated ID. If you're familiar with retrieving process ID's, then you already know what to do using the above commands alone, but if not then that's what we'll cover next, and that's why we launched 'Activity Monitor'. PID may refer to any of the following. Short for product identification or product id, PID is a unique number that helps identify a hardware product or a registered software product. For example, a computer mouse PID is often found on the bottom. If it's a wireless, it may be inside the case, in or near the battery compartment.With software, a 'product ID' is more often referred to as a. Ps -A output has columns pid, tty, time, and cmd. Cmd includes the full command the process was executed with. Use the -c flag to reduce the cmd column output to the process name only. Add an end of line anchor to the grep search string to eliminate the helper processes from the output. Test, learn and program PID control loops in real time with the automated PID Simulator! With the simulated feedback and optional controls, the PID Simulator is the perfect tool to learn, practice, and teach how a PID controller works in a safe environment while maintaining a real world feel.
The way to find the pid on the Mac is to do like this:
which will give us:
Pd For Mac
java 4582 johan 194u IPv6 0x1de155f6b2c74d03 0t0 TCP *:websm (LISTEN)
where 4582 is the pid listening on port 8080. The problem, for me at least, is that this is not a trivial command to remember. To make it simpler I wanted to add it as an alias in .bash_profile in my home directory. The problem now is that aliases won't accept parameters the same way that bash scripts does (by using $@). This is actually not a problem if parameters should be added to the end of an alias. For example consider the following alias:
We've now aliased grep to be case-insensitive so when running for example
we can find the folder called foldername
But in our case the port parameter should not be appended at the end of our alias. So what we have to do to get around this is to first wrap the command in a function and then create an alias to that function:
You can now use pidport 8080 to find the pid of the process listening on port 8080. Prefix lsof with sudo to see process ids that you don't own.

Affordable Mac P&ID Software
As for P&ID software for MAC, Edraw stands tall as one of the most competitive programs ever. It is a great P&ID Designer Visio alternative on Mac OS. Other online programs demand costly monthly or yearly subscription fees while Edraw offers a lifetime license in affordable price.
As a diagramming application coming with extensive symbols and templates and various tools, it's embraced as an effective P&ID desktop program for Mac system, which is selected as the favorite by most of our users.
Full P&ID Symbols
Contains a comprehensive collection of P&ID symbols, including over 1000 black and white P&ID symbols and over 1500 colorful photorealistic shapes. Modify the smart symbols using a floating or pull-down menu. Just drag and drop them to use. Add text to describe the symbols above or below it or anywhere you like. Along with the built-in connection points, it is easier to represent each instrument and how they are inter-connected in the process.
Various P&ID Examples
Here are great P&ID examples that offer you great ideas. You can easily access them right within the software. You can also find more on our website. With these ready to use examples, you are only 1 step away from a desired P&ID. Just fill in your own contents and change the style as you wish. We deal with the hard stuff and users just enjoy the nice and high quality results.
