JOIN(1) User Commands JOIN(1)



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 num-
ber counted from 1. FORMAT is one or more comma or blank separated
specifications, each being `FILENUM.FIELD' or `0'. Default FORMAT out-
puts 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. E.g.,
use `sort -k 1b,1' if `join' has no options.
