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

       --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

       --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.   If  the  input  is  not
       sorted  and  some  lines  cannot  be  joined, a warning message will be
       given.
