NAME

join - join lines of two files on a common field

SYNOPSIS

join[OPTION]... FILE1 FILE2

DESCRIPTION

For each pair of input lines with identical join fields, write a line tostandard output. The default join field is the first, delimitedby whitespace. When FILE1 or FILE2 (not both) is -, read standard input.

-a SIDE: print unpairable lines coming from file SIDE
-e EMPTY: replace missing input fields with EMPTY
-i, --ignore-case ignore differences in case when comparing fields
-j FIELD: (obsolescent) equivalent to `-1 FIELD -2 FIELD'
-j1 FIELD: (obsolescent) equivalent to `-1 FIELD'
-j2 FIELD: (obsolescent) equivalent to `-2 FIELD'
-o FORMAT: obey FORMAT while constructing output line
-t CHAR: use CHAR as input and output field separator
-v SIDE: like -a SIDE, but suppress joined output lines
-1 FIELD: join on this FIELD of file 1
-2 FIELD: join on this FIELD of file 2
--help: display this help and exit
--version: output version information and exit

Unless -t CHAR is given, leading blanks separate fields and are ignored,else fields are separated by CHAR. Any FIELD is a field number countedfrom 1. FORMAT is one or more comma or blank separated specifications,each being `SIDE.FIELD' or `0'. Default FORMAT outputs the join field,the remaining fields from FILE1, the remaining fields from FILE2, allseparated by CHAR.
