I corrected the first one (you can use it if you want to print the filename once per input file).
And yet another version:

Code:
awk '$1 == "ABK" && index($0, "ZBK") == 123 {
  _[FILENAME]++ || $0 = FILENAME RS $0; print 
  }' *

By Sed
Code:
sed -n '/^ABK.\{120\}ZBK/p' urfile

There is a bug in my code: the index function will return the string position only for the first match, so if there is a match before the specific position the record will not be printed even if it contains the required data.

So, the OP should use the substr function.


Code:
... && substr($0,123,3) == "ZBK"


And the bits are for Jim Smilie

Thanks for your reaction radoulov. As a matter of fact I saw this morning in one of our production servers that yesterday's command only worked in some files.

I'm using substr insted of index in your awk command and for now it seems it's working properly, I'll come back to you if I have other problem.

Many thanks for your help!
