I have been using the below syntax in an awk script.
I have large file that consists of 12 columns each separated by a blank space.
Below search criteria works for me on redhat linux 4 and the same syntax shows me no results on redhat linux 5 for the same input file.
when i remove the 12 it works fine again .I just want to know how does this syntax works .
let me know if you have any questions ?
