To search by file type, use the word “kind” and the file type. For example, type “kind:folders” or “kind:audio”. To show the location of a file on your Mac, choose the file from the results list, then p.

I am working on Ubuntu. How can I get MAC address of my machine or an interface say eth0 using C program.

Bruce- It seems no matter how sophisticated our computers get, we still have to deal with unresponsive or frozen programs. Last week’s article was about how to do this on a MAC.
- On the Mac, the equivalent location is the Applications folder, also found in the root directory of the Mac's startup drive (loosely equivalent to the Windows C: drive). Unlike the Program Files directory, the Applications folder is a simple place from which to access and launch applications.
- In the following table, you can find a list of programs that can open files with.mac extension.This list is created by collecting extension information reported by users through the 'send report' option of FileTypesMan utility. The product name, description, and company name are taken from the version information of the.exe file.The 'Actions' list is taken from the context menu items added.
- 4) Find a program you want to open on a Mac Like Search on Windows the Mac has its own feature called Spotlight which will quickly locate any applications, or files, you might need.
- Macs have a thriving ecosystem of software, but some programs still only support Windows. Whether you want to use business software or play Windows PC games, there are many ways to run Windows programs on your Mac. Some of these methods are similar to the ways you can install Windows software on Linux or run Windows programs on a Chromebook. Virtual machines, dual-booting, the Wine compatibility layer, and remote desktop solutions are all included here.

You need to iterate over all the available interfaces on your machine, and use
Charles SalviaCharles Salviaioctl
with SIOCGIFHWADDR
flag to get the mac address. The mac address will be obtained as a 6-octet binary array. You also want to skip the loopback interface.43.7k1111 gold badges109109 silver badges135135 bronze badges
Much nicer than all this socket or shell madness is simply using sysfs for this:
the file
/sys/class/net/eth0/address
carries your mac adress as simple string you can read with fopen()
/fscanf()
/fclose()
. Nothing easier than that.And if you want to support other network interfaces than eth0 (and you probably want), then simply use
haccksopendir()
/readdir()
/closedir()
on /sys/class/net/

You want to take a look at the getifaddrs(3) manual page. There is an example in C in the manpage itself that you can use. You want to get the address with the type

Using getifaddrs you can get MAC address from the family
AF_PACKET
. In order to display the MAC address to each interface, you can proceed like this:

I have just write one and test it on gentoo in virtualbox.

Assuming that c++ code (c++11) is ok as well and the interface is known.

- On Linux, use the service of 'Network Manager' over the DBus.
- There is also good'ol shell program which can be invoke and the result grabbed (use an exec function under C):
$ /sbin/ifconfig | grep HWaddr

A very portable way is to parse the output of this command.
Provided ifconfig can be run as the current user (usually can) and awk is installed (it often is). This will give you the mac address of the machine.

This is a Bash line that prints all available mac addresses, except the loopback:
Can be executed from a C program.
