Sending output of one command to several others?
I know how I can pipe any output to another command thats easy |.
What i'm trying to do is send several addresses to the same command over and over again.
Essentially what I want to do is do an nslookup on an address and then take the resulting IP(s) and send each of those IP's to another follow on command to run for each IP that resutls from the lookup.
Thus far I can do the following to get my output to display strictly the IP's of a lookup.
nslookup yahoo.com | grep -A 20 Non | grep Address | awk '{ print $2 }'
output
69.147.125.65
72.30.2.43
98.137.149.56
209.191.122.70
67.195.160.76
So now how do I get those 5 IP's to each have another command run on them individually and give me the results of the 5 commands it runs.
So as an example how could I run this command then have the system do a ping for each IP and display the results?
If I could figure out how to do this it would save me gobs of typing because i'm always having to lookup domains and then run the test command on each of the resulting IP's for the domain. Which isn't difficult but x20 is time consuming. Would be very nice to just say. yahoo.com GO and get my answers in a second.

Well I can output the IP's to a file. Is there any way I can just run a command and tell the system to run a command for each line of data in a file?

nsquery
nsquery(1) General Commands Manual nsquery(1)
Name
nsquery - name server query command
Syntax
/usr/ucb/nsquery [ lookup ] [ host ] [ server ]
Description
The command provides an interface to obtain host name and address information.
If you specify host, the command obtains information about the specified host. If no host is specified, the command obtains information
about the local host system.
If you specify server, the command queries the BIND server that you specify. If you do not specify a server, the command queries the
default BIND server.
Options
lookup Retrieves the host name, Internet Protocol (IP) address, and aliases of the specified host. If no host or server is specified, the
command obtains information about the local system from the default BIND server.
If you do specify the lookup option, the command obtains the information about the BIND server and host specified (or their
defaults). If the system from which you issue the command is a BIND server, and you do not specify the lookup option, information
about only that server is retrieved.
Files
