+.Sh NAME

+.Sh SYNOPSIS
+.Nm
+.Op Fl a Ar file_number | Fl v Ar file_number
+.Op Fl e Ar string
+.Op Fl j Ar file_number field
+.Op Fl o Ar list
+.Op Fl t Ar char
+.Op Fl \&1 Ar field
+.Op Fl \&2 Ar field
+.Ar file1 file2
+.Sh DESCRIPTION
+The join utility performs an ``equality join'' on the specified files
+and writes the result to the standard output.
+The ``join field'' is the field in each file by which the files are compared.
+The first field in each line is used by default.
+There is one line in the output for each pair of lines in
+.Ar file1
+and
+.Ar file2
+which have identical join fields.
+Each output line consists of the join field, the remaining fields from
+.Ar file1
+and then the remaining fields from
+.Ar file2 .
+.Pp
+The default field separators are tab and space characters.
+In this case, multiple tabs and spaces count as a single field separator,
+and leading tabs and spaces are ignored.
+The default output field separator is a single space character.
+.Pp
+Many of the options use file and field numbers.
+Both file numbers and field numbers are 1 based, i.e. the first file on
+the command line is file number 1 and the first field is field number 1.
+The following options are available:
+.Bl -tag -width Fl
+.It Fl a Ar file_number
+In addition to the default output, produce a line for each unpairable
+line in file
+.Ar file_number .
+(The argument to
+.Fl a
+must not be preceded by a space; see the
+.Sx COMPATIBILITY
+section.)
+.It Fl e Ar string
+Replace empty output fields with
+.Ar string .
+.It Fl o Ar list
+The
+.Fl o
+option specifies the fields that will be output from each file for
+each line with matching join fields.
+Each element of
+.Ar list
+has the form
+.Ql file_number.field ,
+where
+.Ar file_number
+is a file number and
+.Ar field
+is a field number.
+The elements of list must be either comma (``,'') or whitespace separated.
+(The latter requires quoting to protect it from the shell, or, a simpler
+approach is to use multiple
+.Fl o
+options.)
+.It Fl t Ar char
+Use character
+.Ar char
+as a field delimiter for both input and output.
+Every occurrence of
+.Ar char
+in a line is significant.
+.It Fl v Ar file_number
+Do not display the default output, but display a line for each unpairable
+line in file
+.Ar file_number .
+The options
+.Fl v Ar 1
+and
+.Fl v Ar 2
+may be specified at the same time.
+.It Fl 1 Ar field
+Join on the
+.Ar field Ns 'th
+field of file 1.
+.It Fl 2 Ar field
+Join on the
+.Ar field Ns 'th
+field of file 2.
+.El
+.Pp
+When the default field delimiter characters are used, the files to be joined
+should be ordered in the collating sequence of
+.Xr sort 1 ,
+using the
+.Fl b
+option, on the fields on which they are to be joined, otherwise
+.Nm
+may not report all field matches.
+When the field delimiter characters are specified by the
+.Fl t
+option, the collating sequence should be the same as
+.Xr sort 1
+without the
+.Fl b
+option.
+.Pp
+If one of the arguments
+.Ar file1
+or
+.Ar file2
+is ``-'', the standard input is used.
+.Sh EXIT STATUS
+.Ex -std join
+.Sh COMPATIBILITY
+For compatibility with historic versions of
+.Nm ,
+the following options are available:
+.Bl -tag -width Fl
+.It Fl a
+In addition to the default output, produce a line for each unpairable line
+in both file 1 and file 2.
+(To distinguish between this and
+.Fl a Ar file_number ,
+.Nm
+currently requires that the latter not include any white space.)
+.It Fl j1 Ar field
+Join on the
+.Ar field Ns 'th
+field of file 1.
+.It Fl j2 Ar field
+Join on the
+.Ar field Ns 'th
+field of file 2.
+.It Fl j Ar field
+Join on the
+.Ar field Ns 'th
+field of both file 1 and file 2.
+.It Fl o Ar list ...
+Historical implementations of
+.Nm
+permitted multiple arguments to the
+.Fl o
+option.
+These arguments were of the form ``file_number.field_number'' as described
+for the current
+.Fl o
+option.
+This has obvious difficulties in the presence of files named ``1.2''.
+.El
+.Pp
+These options are available only so historic shell scripts don't require
+modification and should not be used.
+.Sh SEE ALSO
+.Xr awk 1 ,
+.Xr comm 1 ,
+.Xr paste 1 ,
+.Xr sort 1 ,
+.Xr uniq 1
+.Sh STANDARDS
+The
+.Nm
+command is expected to be
+.St -p1003.2
+compatible.
