Shell Programming and Scripting

Hi there I have a script which uses awks "{print $NF} function to print the last field in a space delimited line

it turns out that the output i am awking against has changed and now i need to get the 3rd column in from the right (the one highlighted in red below). Is there an easy way to do this by using $NF and counting backwards, or am i going to have to do a field count from the left ?

Code:

Product Name          : INTEL(R) XEON(R) CPU           E5540  @ 2.53GHZ

any help would be great

Hi

Code:

print $(NF-2)

thanks Scott, I seem to be having a few issues with that ... let me paste my code

My original command to retrieve the last field was

Code:

 # ipmitool fru | nawk '!NF{f=0};/(p0.fru|MB\/P0 \()/{f=1} ; /Product Name/&&f{print $NF}'

Ive tried a few variations of adding the -2 to the final print command with no success, for example

Code:

 # ipmitool fru | nawk '!NF{f=0};/(p0.fru|MB\/P0 \()/{f=1} ; /Product Name/&&f{print NF-2}'
7

Could you let me know how this would work because obviously NF-2 will will just give me 7 (i.e the correct field number)

How about if you try this...

Code:

ipmitool fru | nawk '!(NF-2){f=0};/(p0.fru|MB\/P0 \()/{f=1} ; /Product Name/&&f{print $(NF-2)}'

its ok i got it (misread the folowing as something else - DOH)

$(NF-2)
