awk

[hirohitosan]

Hello. I just started to learn the awk language and I tried some examples from doc folder. And there is an example like this:

Print the length of the longest input line:

awk '{ if (lenght ($0) > max ) max = lenght ($0) } END { print max }' CV-NA-10mVps02.Txt

and the result was:

[PHASE], 3, 1415, 4

I asumed that this will give me a value not a string, and that line is NOT the longest input line.

Does anyone knows something about AWK arround here or where I can find someone for explanations?

thanx

awk '{ if (lenght ($0) > max ) max = lenght ($0) } END { print max }' CV-NA-10mVps02.Txt

 

the only thing i can see immediately is that the spelling of LENGTH is wrong.....try it spelled this way instead...i dont know AWK at all im afraid, but that is the first obvious thing.

I want to use AWK for calculations in some scientific data. I did some experiments and the machine gave me a *.txt file, like this:

A1, A2, A3, A4, ..., An

B1, B2, B3, B4, ..., Bn

C1, C2, C3, C4, ..., Cn

.....................................

M1, M2, M3, M4, ..., Mn

N1, N2, N3, N4, ..., Nn

 

I'm wondering if I could do some operations like:

cap=A3*(B2-B1)+B3*(C2-C1)+...+M3*(N2-N1)

 

Or someone knows some forums on AWK where I can aks some questions?

 

Thanx

hi again,

 

theres an old english phrase - 'sometimes you cant see the wood for the trees'

i know what its like when you are deep in the middle of something....you dont always spot the obvious!

i do a lot of VBA coding, and i have a co worker read everything, not to see if the code is right, but to make sure theres no typos!
