Code:
awk '{ T=0; C=0; for(N=1; N<=NF; N++) if($N != "X") { T+=$N; C++ } $(NF+1)=T/C } 1' input

Hmm, this code does not really achieve that. What I meant was that the code should take the average of the "non X" values in a single row and print it in the last column.

Sample input:
Code:
Aa 100 X X
Bb 100 200 300
Cc 100 200 X

Output:
Code:
Aa 100 X X 100
Bb 100 200 300 200
Cc 100 200 X 150

In what way does it not "achieve that"?

Sample input:

Code:
Aa 100 X X
Bb 100 200 300
Cc 100 200 X

Sample output
Code:
Aa 100 X X 50
Bb 100 200 300 150
Cc 100 200 X 100

I see the problem. Change N=1 to N=2 so it starts at the second field instead of the first.
