i.e. do an ifconfig -a, then grep for the common keyword denominating each virtual interface
extract the part of each result from grep, possibly using something to the following effect
where <#> represents the column number (in order from left-to-right starting at 1) containing the unique interface id, it's prolly $1 for first column, if memory serves me proper!
if the above command statement works (or whatever you get to work), then store it to a variable and run a for-loop on it
e.g. if the above worked perfectly...
#note that the commandstatement is enclosed in back-quotes (key next to number-1 and usually on same key with ~
Then run whatever set of commands you want done for each interface
where $i will represent the interface name in each iteration of the for-loop; you can substitute i with any expression, but when writing the command statement to be performed for each interface (after the do statement), represent interface name with whatever subsitute for i you use, precede with $ (like any normal variable)
for-loop uses i as a variable to represent each entry in the $TEMPLIST
Hi there,
I have numerous files in a directory (approx 2500) that I want to delete although I get the following:-
Server> rm *.*
Arguments too long
Is there a proper way of deleting this rather than breaking it down further through the list of files
rm *10.*
rm *11.*
rm *12.*

Hi there!
Have literally just started using UNIX bash shell again and am writing simple scripts in VI.
I basically have a working script but I know without a doubt it could be condensed down to much less code by integrating the individual IF statements.
Here is my shoddy code :)

Hi Al,
In course of understanding networking in Solaris, I have these doubts on Interfaces. Please clarify me. I have done fair research in this site and others but could not be clarified.

Hey!
I wanted to find a text version of the Bible for purposes of grepping. The only files I could find, (in the translation I wanted), were Old Testament.txt and New Testament.txt.

EPAIR(4) BSD Kernel Interfaces Manual EPAIR(4)NAME
epair -- A pair of virtual back-to-back connected Ethernet interfaces.
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device epair
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_epair_load="YES"
DESCRIPTION
The epair is a pair of Ethernet-like software interfaces, which are connected back-to-back with a virtual cross-over cable.
Each epair interface pair is created at runtime using interface cloning. This is most easily done with the ifconfig(8) create command or
using the cloned_interfaces variable in rc.conf(5). While for cloning you only give either epair or epair<n> the epair pair will be named
like epair<n>[ab]. This means the names of the first epair interfaces will be epair0a and epair0b.
Like any other Ethernet interface, an epair needs to have a network address. Each epair will be assigned a locally administered address by
default, that is only guaranteed to be unique within one network stack. To change the default addresses one may use the SIOCSIFADDR ioctl(2)
or ifconfig(8) utility.
The basic intend is to provide connectivity between two virtual network stack instances. When connected to a if_bridge(4) one end of the
interface pair can also be part of another (virtual) LAN. As with any other Ethernet interface one can configure vlan(4) support on top of
it.

The epair interface first appeared in FreeBSD 8.0.
