           14 .Sh DESCRIPTION
           15 .Nm
           16 writes the sorted concatenation of each
           17 .Ar file
           18 to stdout.
           19 If no
           20 .Ar file
           21 is given
           22 .Nm
           23 reads from stdin.
           24 .Sh OPTIONS
           25 .Bl -tag -width Ds
           26 .It Fl C
           27 Check that the concatenation of the given
           28 .Ar files
           29 is sorted rather than sorting them.
           30 In this mode, no output is printed to stdout, and the exit status
           31 indicates the result of the check.
           32 .It Fl b
           33 Skip leading whitespace of columns when sorting.
           34 .It Fl c
           35 The same as
           36 .Fl C
           37 except that when disorder is detected, a message is written to stderr
           38 indicating the location of the disorder.
           39 .It Fl d
           40 Skip non-whitespace and non-alphanumeric characters.
           41 .It Fl f
           42 Ignore letter case when sorting.
           43 .It Fl i
           44 Skip non-printable characters.
           45 .It Fl k Ar key
           46 Specify a key definition of the form
           47 .Sm off
           48 .Sy S
           49 .No [.
           50 .Sy s

           59 .No ]]
           60 .Sm on
           61 where
           62 .Sy S , s , E
           63 and
           64 .Sy e
           65 are the starting column, starting character in that column, ending column and
           66 the ending character of that column respectively.
           67 If they are not specified,
           68 .Sy s
           69 refers to the first character of the specified starting column,
           70 .Sy E
           71 refers to the last column of every line, and
           72 .Sy e
           73 refers to the last character of the ending column.
           74 .Sy f
           75 can be used to specify options
           76 .Sy ( n , b )
           77 that only apply to this key definition.
           78 .Sy b
           79 is special in that it only applies to the column that it was specified after.
           80 .It Fl m
           81 Assume sorted input, merge only.
           82 .It Fl n
           83 Perform a numeric sort.

           85 Write output to

           89 Reverses the sort.
           90 .It Fl t Ar delim
           91 Set
           92 .Ar delim
           93 as the field delimiter.
           94 .It Fl u
           95 Print equal lines only once.
