awk 'FNR==1 {++counter} # fine, you count no. of files
counter ==2 {BB[$1]=1; next} # from the second file, keep $1. But, there's no second file, as scrutinizer pointed out.
substr($0,26,2) =="01") {next} # is never met in your sample input, which is fine if you want to keep all lines. One closing paranthesis too many!
(substr($0,28,12) ~ "^[A-Z,a-z]") {next} # would succeed on your tar's second input line if you came that far
(substr($0,184,3) in BB) {next} # your longest line has 177 chars
1
' bb.txt # just one file to work upon; see scrutinizer's post
All your code does is print your bb.txt lines.
If you need further help, specify what output you want from which input based on which logic, in plain English.
How about applying our advices and creating / testing a revised code. If that does not work, come back for help. One more comment: As the bb.txt file entries and thus BB elements are having 4 chars, they will never match substr ($0, 184,3)...
tried changing code to as follows(used if condition) in case required i can pull other data using else if condition(for future requirement if any), but this prints the complete samplefile data (matching the condition)and not the substrs as mentioned in code below(see the printf). Please look into this & suggest
