Shell Commands
Display all network interface names on any Linux system from the shell:
/sbin/ifconfig | grep BROADCAST | cut -d " " -f1 | sed 's/.$//'
Most Linux machines will only display one network interface, such as shown on my Slackware 14.1 Virtual Machine Server:
eth0
Other systems may have more than one, such as those with virtual machine software.
Also, some systems use non-standared network interface names, other than the usual eth0.
Here are some samples of those types of systems:
Sample output from my Fedora 20 (Heisenbug) VirtualBox server:
em1 virbr0
And here is a sample output from my Fedora 17 (Beefy Miracle) laptop running VMWare:
p5p1 vmnet1 vmnet8
The "ps" Process Command Syntax
To show all executing processes:
$ ps ax
To show all processed running by a specific user(This example shows all processes running by the Apache WebServer):
$ ps -U apache
