Switching the values in a specific column of a text file

Hi,

I have a space de-limited text file. In the fifth column, I would like to switch "1"s with "2"s. How do I go about doing that? Thanks!

Sample input:
Code:
0 311000259 0 0 1 1
0 311000397 0 0 1 2
0 311000491 0 0 2 1
0 311000516 0 0 2 1
0 311000541 0 0 1 1
0 311000558 0 0 2 1
0 311000566 0 0 2 1

Sample output:
Code:
0 311000259 0 0 1 2
0 311000397 0 0 1 1
0 311000491 0 0 2 2
0 311000516 0 0 2 2
0 311000541 0 0 1 2
0 311000558 0 0 2 2
0 311000566 0 0 2 2

I think you meant 6-th column (based on your sample output):
Code:
awk '$6=($6==1)?2:1' myFile
