[Jorge Infante]

Hi.
I'm having problem with join command.
I have 2 files:
file1 and file2, ordered by field 1.
 file2 content:

 I'm running:
join -t "|" -j 1 -a 2 file1 file2 
 The result is:
163|reg000524
 I have a record with value "163" in file2.
 Is a bug?
 Im using:
join (coreutils) 5.2.1
 running on debian sarge kernel 2.4.27 #1
 Is a bug or I'm executing join command with incorrect parameters?
