Hello everyone.

I was trying to get another data but i am having problem with field seperator based on the log sample below.

main
Code:
|08:52:01.304|0x00001450|2 |        |RAM_24   |      RBL: RBL Code 10   
|08:52:01.304|0x00001450|2 |        |RAM_24   |      DRPD: DRPD 789123
|08:52:01.304|0x00001450|2 |        |RAM_24   |      RTR: RTR Incomplete

trigger
Code:
|08:52:01.335|0x00001450|-1|        |BIOPDB    |.\ESRvalueafter(618) : Caught ERROR(MFC) exception - BIOS-INFO20530: Alert on the bios get info on top

If the log sample has a seperator of something like this below i works

fs=':\\| +'; main='RBL: '; trig='BIOS-INFO'
awk -F"$fs" -v main="$main" -v trig="$trig" '$2 ~ main { first = $0; getline; second = $0; getline; third = $0; } first && $2 ~ trig { printf "%s\n%s\n%s\n", first, second, third }' INPUTFILE

main
Code:
|08:52:01.304|0x00001450|2 |        |RAM_24   :|      RBL: RBL Code 10   
|08:52:01.304|0x00001450|2 |        |RAM_24   :|      DRPD: DRPD 789123
|08:52:01.304|0x00001450|2 |        |RAM_24   :|      RTR: RTR Incomplete

trigger
Code:
|08:52:01.335|0x00001450|-1|        |BIOPDB    :|.\ESRvalueafter(618) : Caught ERROR(MFC) exception - BIOS-INFO20530: Alert on the bios get info on top

but using the sample log above with the using this it doesn't get any output.

fs='|'; main='RBL: '; trig='BIOS-INFO'
awk -F"$fs" -v main="$main" -v trig="$trig" '$6 ~ main { first = $0; getline; second = $0; getline; third = $0; } first && $6 ~ trig { printf "%s\n%s\n%s\n", first, second, third }' INPUTFILE

anyone can explain why? i can't understand why with FS :\\| it works and assign field var to $2. could anyone disect it please. thanks
