Hi,
I am stuck with extracting values by combining 2 dynamically extracted values.
The code goes like this
#!/usr/bin/ksh
ID1="abcd"
i=1 #this is a dynamic value and keeps on changing
b="ID" #this is static
now i want the value of ID1 variable.
like echo $b$i
But echo... (1 Reply)

second="two"
third="three"
myvar="first"
echo ${!myvar}
But this gives error 'bad substitution'

iwspy
IWSPY(8) Linux Programmer's Manual IWSPY(8)NAME
iwspy - Get wireless statistics from specific nodes
SYNOPSIS
iwspy [interface]
iwspy interface [+] DNSNAME | IPADDR | HWADDR [...]
iwspy interface off
iwspy interface setthr low high
iwspy interface getthr
DESCRIPTION
Iwspy is used to set a list of addresses to monitor in a wireless network interface and to read back quality of link information for each
of those. This information is the same as the one available in /proc/net/wireless : quality of the link, signal strength and noise level.
This information is updated each time a new packet is received, so each address of the list adds some overhead in the driver.
Note that this functionality works only for nodes part of the current wireless cell, you can not monitor Access Points you are not associ-
ated with (you can use Scanning for that) and nodes in other cells. In Managed mode, in most case packets are relayed by the Access Point,
in this case you will get the signal strength of the Access Point. For those reasons this functionality is mostly useful in Ad-Hoc and Mas-
ter mode.
PARAMETERS
You may set any number of addresses up to 8.
DNSNAME | IPADDR
Set an IP address, or in some cases a DNS name (using the name resolver). As the hardware works with hardware addresses, iwspy will
translate this IP address through ARP. In some case, this address might not be in the ARP cache and iwspy will fail. In those case,
ping(8) this name/address and retry.
HWADDR Set a hardware (MAC) address (this address is not translated & checked like the IP one). The address must contain a colon (:) to be
recognised as a hardware address.
+ Add the new set of addresses at the end of the current list instead of replacing it. The address list is unique for each device, so
each user should use this option to avoid conflicts.
off Remove the current list of addresses and disable the spy functionality
setthr Set the low and high signal strength threshold for the iwspy event (for drivers that support it).
Every time the signal strength for any of the address monitored with iwspy goes lower than the low threshold or goes higher than the
high threshold, a Wireless Event will be generated.
This can be used to monitor link outages without having to run iwspy periodically.
getthr Retrieve the current low and high signal strength threshold for the iwspy event.
