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 to
standard output. The default join field is the first, delimited
by whitespace. When FILE1 or FILE2 (not both) is -, read standard input.
-a FILENUM
print unpairable lines coming from file FILENUM, where
FILENUM is 1 or 2, corresponding to FILE1 or FILE2
-e EMPTY
replace missing input fields with EMPTY
-i, --ignore-case ignore differences in case when comparing fields
-j FIELD
equivalent to `-1 FIELD -2 FIELD'
-o FORMAT
obey FORMAT while constructing output line
-t CHAR
use CHAR as input and output field separator
-v FILENUM
like -a FILENUM, 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 counted
from 1. FORMAT is one or more comma or blank separated specifications,
each being `FILENUM.FIELD' or `0'. Default FORMAT outputs the join field,
the remaining fields from FILE1, the remaining fields from FILE2, all
separated by CHAR.
Important: FILE1 and FILE2 must be sorted on the join fields.
