RE: using wget, checkip.dyndns.org, and sed

Hi, Karma The "cut" and "awk" commands used in your examples produced slightly different results, but each example was most helpful in illustrating the basics of these two commands. I now have two command options for filtering output/text. Cut produces: Current IP Address: 208.106.8.22 AWK produces: 208.106.8.22 Thank you kindly,

Hi, Karma

Cut produces: Current IP Address: 208.106.8.22

using wget, checkip.dyndns.org, and sed

I am trying to get my external Ip using cygwin on a Windows 7 box. I am almost there but I am having an issue with the sed substitution syntax. As you see, I am getting the IP, but I don't want the part of the output. C:\>wget -q http://checkip.dyndns.org -O index1.html && sed "s/.*:\(.*\)<.*/\1/" index1.html 208.106.78.22 Without the -q switch the output is: Current IP CheckCurrent IP Address: 206.108.78.2 How do I have to change the sed command? Instead of creating the index1.html file, I also tried unsuccessfully to use pipe and grep, but failed to get that working properly. Alternative approaches would also be appreciated, but I would like to know what I am doing wrong with the sed commands. I have tried many different variations, but just can't seem to get just the IP address. Thank you, mgd

I am trying to get my external Ip using cygwin on a Windows 7 box. I am almost there but I am having an issue with the sed substitution syntax. As you see, I am getting the IP, but I don't want the </body> part of the output.

C:\>wget -q http://checkip.dyndns.org -O index1.html && sed "s/.*:\(.*\)<.*/\1/" index1.html
208.106.78.22</body>

Without the -q switch the output is:

<html><head><title>Current IP Check</title></head><body>Current IP Address: 206.108.78.2</body></html>

How do I have to change the sed command? Instead of creating the index1.html file, I also tried unsuccessfully to use pipe and grep, but failed to get that working properly. Alternative approaches would also be appreciated, but I would like to know what I am doing wrong with the sed commands.
