While loop using command output...
If I run this command
Code:
networksetup -listallnetworkservices

I get the following output.
Code:
Ethernet
AirPort
*Parallels Host-Guest
*Parallels NAT
MY VPN
Ethernet 2

I want to make changes to only anything that contains the word "Ethernet" which I can do with grep.
But What I really need a little help is with a While loop run this command on each of my adapters.

Thanks in advance.

#!/bin/ksh
networksetup -listallnetworkservices |grep Ethernet | while read LINE
do
#   do what need to do with $LINE
done

This is probably is REAL DUMB NOOB question, and I SHOULD know this by now.... but can I run this a standard sh script because you used #!/bin/ksh Instead of #!/bin/sh

Code:
networksetup -listallnetworkservices |grep Ethernet | while read LINE
do
networksetup -setwebproxy $LINE com.intranet.proxy 8080
networksetup -setautoproxyurl $LINE http://config.proxy.
networksetup -setautoproxystate $LINE off
done

I get this as a return
Code:
** Error: The parameters were not valid.
** Error: The parameters were not valid.


If I do echo it goes display the correct information, does this do line by line or entire output?
Also If I manually enter each command with each Ethernet output, but get this via script.

that appears to be an error from networksetup not from the looping. Check your commands.

you might need to put double quotes:
Code:
networksetup -listallnetworkservices |grep Ethernet | while read LINE
do
networksetup -setwebproxy "$LINE" com.intranet.proxy 8080
networksetup -setautoproxyurl "$LINE" http://config.proxy.
networksetup -setautoproxystate "$LINE" off
done
