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
#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
Code:
$ for i in $TEMPLIST
do
command1 $i
done
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 :)

EDSC(4) BSD Kernel Interfaces Manual EDSC(4)NAME
edsc -- Ethernet discard network interface
SYNOPSIS
device edsc
DESCRIPTION
The edsc interface is a software discard mechanism which may be used for performance analysis and software testing. It imitates an Ethernet
device, which allows for its use in conjunction with such drivers as if_bridge(4) and vlan(4).
As with other network interfaces, an edsc interface must have network addresses assigned for each address family with which it is to be used.
These addresses may be set or changed with the SIOCSIFADDR ioctl(2) or ifconfig(8) utility.
Each edsc interface 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).
SEE ALSO ioctl(2), arp(4), if_bridge(4), inet(4), intro(4), vlan(4), rc.conf(5), arp(8), ifconfig(8)HISTORY
The edsc device was derived from the disc(4) device and first appeared in FreeBSD 6.3. This manpage was adapted from disc(4).
CAVEATS
Since outgoing packets are just discarded by edsc, ARP requests stay unreplied. Consequently, an IP packet cannot be sent via edsc until a
static arp(4) entry is created for its next hop using arp(8).
Initially an edsc interface has a zero link level address. It can be changed with ifconfig(8) lladdr if needed.
