Shell Programming and Scripting

Hi All,
Hoping you can help as im in desperate need... I'm very new to unix scripting so apoligies,

I have setup an expect script in order to log into a node on our network, This will provide an output as per the below

Code:

*********** information:
    *************: n/a
    TEST IP : n/a
    ****************: n/a                  ***************: n/a

  ********* Information:
    **********: 345:66:25434
    **********: 345:66:8468
    *********: n/a
    *******************: n/a
    *******************:
      ***** ***** **: 33:345:66
      TEST IP : 123.45.67.89

What I need to be able to do is read the IP address next to where it says TEST IP and then use this in another command. Problem I have is the IP does not always display in the bottom TEST IP line sometimes it can be in the first TEST IP line and N/A will be next to the second.

Essentially I need to read the IP address next to TEST IP and then use in another command. Would anyone be kind enough to help me out please. Sorry for the stars but as its security info I cant show it.

Thanks In advance.

This should output IP from lines with TEST IP

Code:

awk -F"[ :]+" --posix '$0~/TEST IP/ && $4~/^([0-9]{1,3}\.){3}[0-9]{1,3}$/ {print $4}' file

Code:

awk '/TEST IP/&&!/n\/a/{print $NF}' file

Thanks for your response's guys, So this is a print output from within an expect script. I need the IP addresses to be read and then I want to execute another command using that ip as the variable.

How would you recommend is best to do this.

Log to a file and run the awk on that file when the time comes.

if the next script is occuring almost simultaneously with the first script, you can just set a variable to the value of the ip address and then run the next command (see sample below) ...

Code:

MYIP=$(awk '/TEST IP/ && !/n\/a/ {print $2}'  file)
ping $MYIP

If this condition is true for more than one IP
MYIP=$(awk '/TEST IP/ && !/n\/a/ {print $2}' file)
you can use exit to get only the first.
MYIP=$(awk '/TEST IP/ && !/n\/a/ {print $2;exit}' file)
This will make this work ping $MYIP
