default join field is the first, delimited by blanks.
When `FILE1` or `FILE2` (not both) is `-`, read standard input.
SYNOPSIS
join [-a ] [-v ] [-e ] [-i|--ignore-case] [-j ] [-o ] [-t ] [-1 ] [-2 ] [--check-order] [--nocheck-order]
[--header] [-z|--zero-terminated] [-h|--help] [-V|--version] <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 blanks.
When `FILE1` or `FILE2` (not both) is `-`, read standard input.
OPTIONS
-a=FILENUM
also print unpairable lines from file FILENUM, where FILENUM is 1 or 2, corresponding to FILE1 or
FILE2
[possible values: 1, 2]
-v=FILENUM
like -a FILENUM, but suppress joined output lines
[possible values: 1, 2]
-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
-1=FIELD
join on this FIELD of file 1
-2=FIELD
join on this FIELD of file 2
--check-order
check that the input is correctly sorted, even if all input lines are pairable
--nocheck-order
do not check that the input is correctly sorted
--header
treat the first line in each file as field headers, print them without trying to pair them
