Join or Awk
Is is possible to join on unsorted files by a string? Don't want to sort because there is other text that is already in a good format.

I want to replace or join RBOSK-374 in file 2 with NB2781 FGH in file 1.
Any help would be appreciated.

Code:
a.log: RBOSK-374 AAA-B04-D16-K01
a.log: 0 XXX 602 14/1 R14A 
a.log: 2 XXX 119 128/1 R1B 
a.log: 3 XXX 119 128/1 R1B 
a.log: 4 XXX 119 128/1 R1B 
a.log: 5 XXX 231 201/1 R10B 
a.log: 6 XXX 231 201/1 R5C 
b.log: RBOSK-70 NB9292 
b.log: RBOSK-374 NB2781 
b.log: RBOSK-73 JO1794 
b.log: RBOSK-83 OK1987 
b.log: RBOSK-85 LY1983

I would want to file "a" to be like this:
Code:
a.log: NB2781 AAA-B04-D16-K01 
a.log: 0 XXX 602 14/1 R14A 
a.log: 2 XXX 119 128/1 R1B 
a.log: 3 XXX 119 128/1 R1B 
a.log: 4 XXX 119 128/1 R1B 
a.log: 5 XXX 231 201/1 R10B 
a.log: 6 XXX 231 201/1 R5C

Try:
Code:
awk 'NR==FNR{A[$1]=$2; next} $1 in A{$1=A[$1]}1' b.log a.log
