-.Dd January 13, 2001
-.Dt SORT 1
-.Os
-.Sh NAME
-.Nm sort
-.Nd sort or merge text files
-.Sh SYNOPSIS
-.Nm sort
-.Op Fl cmubdfHinrsS
-.Op Fl t Ar char
-.Op Fl R Ar char
-.Oo
-.Fl k
-.Ar field1 Ns Op Li \&, Ns Ar field2
-.Oc
-.Op Fl T Ar dir
-.Op Fl o Ar output
-.Op Ar
-.Sh DESCRIPTION
-The
-.Nm
-utility sorts text files by lines.
-Comparisons are based on one or more sort keys extracted
-from each line of input, and are performed lexicographically.
-By default, if keys are not given,
-.Nm
-regards each input line as a single field.
-.Pp
-The following options are available:
-.Bl -tag -width Fl
-.It Fl c
-Check that the single input file is sorted.
-If the file is not sorted,
-.Nm
-produces the appropriate error messages and exits with code 1; otherwise,
-.Nm
-returns 0.
-.Nm
-.Fl c
-produces no output.
-.It Fl m
-Merge only; the input files are assumed to be pre-sorted.
-.It Fl o Ar output
-The argument given is the name of an
-.Ar output
-file to be used instead of the standard output.
-This file can be the same as one of the input files.
-.It Fl T Ar dir
-Use
-.Ar dir
-as the directory for temporary files.
-The default is the value specified in the environment variable
-.Ev TMPDIR or
-.Pa /tmp
-if
-.Ev TMPDIR
-is not defined.
-.It Fl u
-Unique: suppress all but one in each set of lines having equal keys.
-If used with the
-.Fl c
-option, check that there are no lines with duplicate keys.
-.El
-.Pp
-The following options override the default ordering rules.
-When ordering options appear independent of key field
-specifications, the requested field ordering rules are
-applied globally to all sort keys.
-When attached to a specific key (see
-.Fl k ) ,
-the ordering options override
-all global ordering options for that key.
-.Bl -tag -width Fl
-.It Fl d
-Only blank space and alphanumeric characters
-according
-to the current setting of LC_CTYPE
-are used
-in making comparisons.
-.It Fl f
-Considers all lowercase characters that have uppercase
-equivalents to be the same for purposes of comparison.
-.It Fl i
-Ignore all non-printable characters.
-.It Fl n
-An initial numeric string, consisting of optional blank space, optional
-minus sign, and zero or more digits (including decimal point)
-.\" with
-.\" optional radix character and thousands
-.\" separator
-.\" (as defined in the current locale),
-is sorted by arithmetic value.
-(The
-.Fl n
-option no longer implies the
-.Fl b
-option.)
-.It Fl r
-Reverse the sense of comparisons.
-.It Fl S
-Don't use stable sort.
-Default is to use stable sort.
-.It Fl s
-Use stable sort.
-This is the default.
-Provided for compatiblity with other
-.Nm
-implementations only.
-.It Fl H
-Use a merge sort instead of a radix sort.
-This option should be used for files larger than 60Mb.
-.El
-.Pp
-The treatment of field separators can be altered using these options:
-.Bl -tag -width Fl
-.It Fl b
-Ignores leading blank space when determining the start
-and end of a restricted sort key.
-A
-.Fl b
-option specified before the first
-.Fl k
-option applies globally to all
-.Fl k
-options.
-Otherwise, the
-.Fl b
-option can be attached independently to each
-.Ar field
-argument of the
-.Fl k
-option (see below).
-Note that the
-.Fl b
-option has no effect unless key fields are specified.
-.It Fl t Ar char
-.Ar char
-is used as the field separator character.
-The initial
-.Ar char
-is not considered to be part of a field when determining
-key offsets (see below).
-Each occurrence of
-.Ar char
-is significant (for example,
-.Dq Ar charchar
-delimits an empty field).
-If
-.Fl t
-is not specified, the default field separator is a sequence of
-blank-space characters, and consecutive blank spaces do
-.Em not
-delimit an empty field; further, the initial blank space
-.Em is
-considered part of a field when determining key offsets.
-.It Fl R Ar char
-.Ar char
-is used as the record separator character.
-This should be used with discretion;
-.Fl R Ar \*[Lt]alphanumeric\*[Gt]
-usually produces undesirable results.
-The default record separator is newline.
-.It Xo
-.Fl k
-.Ar field1 Ns Op Li \&, Ns Ar field2
-.Xc
-Designates the starting position,
-.Ar field1 ,
-and optional ending position,
-.Ar field2 ,
-of a key field.
-The
-.Fl k
-option replaces the obsolescent options
-.Cm \(pl Ns Ar pos1
-and
-.Fl Ns Ar pos2 .
-.El
-.Pp
-The following operands are available:
-.Bl -tag -width Ar
-.It Ar file
-The pathname of a file to be sorted, merged, or checked.
-If no
-.Ar file
-operands are specified, or if
-a
-.Ar file
-operand is
-.Fl ,
-the standard input is used.
-.El
-.Pp
-A field is defined as a minimal sequence of characters followed by a
-field separator or a newline character.
-By default, the first
-blank space of a sequence of blank spaces acts as the field separator.
-All blank spaces in a sequence of blank spaces are considered
-as part of the next field; for example, all blank spaces at
-the beginning of a line are considered to be part of the
-first field.
-.Pp
-Fields are specified
-by the
-.Fl k
-.Ar field1 Ns Op \&, Ns Ar field2
-argument.
-A missing
-.Ar field2
-argument defaults to the end of a line.
-.Pp
-The arguments
-.Ar field1
-and
-.Ar field2
-have the form
-.Ar m Ns Li \&. Ns Ar n
-and can be followed by one or more of the letters
-.Cm b , d , f , i ,
-.Cm n ,
-and
-.Cm r ,
-which correspond to the options discussed above.
-A
-.Ar field1
-position specified by
-.Ar m Ns Li \&. Ns Ar n
-.Pq Ar m , n No \*[Gt] 0
-is interpreted as the
-.Ar n Ns th
-character in the
-.Ar m Ns th
-field.
-A missing
-.Li \&. Ns Ar n
-in
-.Ar field1
-means
-.Ql \&.1 ,
-indicating the first character of the
-.Ar m Ns th
-field; if the
-.Fl b
-option is in effect,
-.Ar n
-is counted from the first non-blank character in the
-.Ar m Ns th
-field;
-.Ar m Ns Li \&.1b
-refers to the first non-blank character in the
-.Ar m Ns th
-field.
-.Pp
-A
-.Ar field2
-position specified by
-.Ar m Ns Li \&. Ns Ar n
-is interpreted as
-the
-.Ar n Ns th
-character (including separators) of the
-.Ar m Ns th
-field.
-A missing
-.Li \&. Ns Ar n
-indicates the last character of the
-.Ar m Ns th
-field;
-.Ar m
-= \&0
-designates the end of a line.
-Thus the option
-.Fl k
-.Sm off
-.Xo
-.Ar v Li \&. Ar x Li \&,
-.Ar w Li \&. Ar y
-.Xc
-.Sm on
-is synonymous with the obsolescent option
-.Sm off

-.Sh RETURN VALUES
-Sort exits with one of the following values:
-.Bl -tag -width flag -compact
-.It 0
-Normal behavior.
-.It 1
-On disorder (or non-uniqueness) with the
-.Fl c
-option
-.It 2
-An error occurred.

-.Sh ENVIRONMENT
-If the following environment variable exists, it is utilized by

-environment variable as the path in which to store
-temporary files.

-.Sh FILES
-.Bl -tag -width outputNUMBER+some -compact
-.It Pa /tmp/sort.*
-Default temporary files.
-.It Pa Ar output Ns NUMBER
-Temporary file which is used for output if
-.Ar output
-already exists.
-Once sorting is finished, this file replaces
-.Ar output
-(via
-.Xr link 2
-and
-.Xr unlink 2 ) .
-.El
-.Sh SEE ALSO
-.Xr comm 1 ,
-.Xr join 1 ,
-.Xr uniq 1 ,
-.Xr qsort 3 ,
-.Xr radixsort 3
-.Sh HISTORY
-A
-.Nm
-command appeared in
-.At v5 .
-This
-.Nm
-implementation appeared in
-.Bx 4.4
-and is used since
-.Nx 1.6 .
-.Sh BUGS
-The locale's collating order is applied on a per-character basis, so
-double character letters like "ss" are not collated correctly.
-.Pp
-To sort files larger than 60Mb, use
-.Nm
-.Fl H ;
-files larger than 704Mb must be sorted in smaller pieces, then merged.
-.Sh NOTES
-This
-.Nm
-has no limits on input line length (other than imposed by available
-memory) or any restrictions on bytes allowed within lines.
-.Pp
-To protect data
-.Nm
-.Fl o
-calls
-.Xr link 2
-and
-.Xr unlink 2 ,
-and thus fails on protected directories.
-.Pp
-Input files should be text files.
-If file doesn't end with record separator (which is typically newline), the
-.Nm
-utility silently supplies one.
-.Pp
-The current
-.Nm
-uses lexicographic radix sorting, which requires
-that sort keys be kept in memory (as opposed to previous versions which used quick
-and merge sorts and did not.)
-Thus performance depends highly on efficient choice of sort keys, and the
-.Fl b
-option and the
-.Ar field2
-argument of the
-.Fl k
-option should be used whenever possible.
-Similarly,
-.Nm
-.Fl k1f
-is equivalent to
-.Nm
-.Fl f
-and may take twice as long.
