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 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

this FIELD of file 2
--help

--version

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
`SIDE.FIELD' or `0'. Default FORMAT outputs the join field,
the remaining fields from FILE1, the remaining fields from
FILE2, all separated by CHAR.
