I have another question. In my original awk statement I took for granted that there won't be more that 4 fields. However I ran into a situation where I won't know how many fields there can be.

test2 test4 test5 100000837474

could be
test2 test4 test5 test6 test7 100000837474

So I was thinking how can I check the line for the first occurrence of a numeric variable.?

I have another issue where I thought that I won't have more than 4 fields. It turns out I won't know how many fields I will have. How can I check the line for the first occurrence of a numeric variable with awk??

Did you try post#4 ?

And why do you want to check the first occurrence for numeric?

I did not try #4. I figured that out.
What I need to do now is look at the number in my file and determine if it is bigger than 1TB. However it now appears that it won't only be 4 fields. It can be more than that.
So I need a way to check the number.
I figured if I can fo through the line and when it is numeric check the size.

Orginal file
test test2 1000000657373
test1 test3 1000003849450
test2 test4 test5 100000837474

However my file can also look like

test test2 1000000657373
test1 test3 1000003849450
test2 test4 test5 test6 test7 100000837474

and maybe more columns.

Check $NF.

Use $NF to access the last field.

Having hard time making the NF work. One of my line of output is
tree         8 vf_MTLHQNASF09_Wkgp3 Agile Delivery Services   2980176 1572864000      79       - /vol/vf_MTLHQNASF09_Wkgp3/Agile Delivery Services

So how do I get
/vol/vf_MTLHQNASF09_Wkgp3/Agile Delivery Services

this. As you can see there are spaces. And this is not constant. I would not know what that would be.

How does this (from post #10) fit to your post #13? (<--- GIANT question mark)
