In this mode, no output is printed to 30 stdout, and the exit status indicates the result of the check. 31 .It Fl b 32 Skip leading whitespace of columns when sorting. 33 .It Fl c 34 The same as 35 .Fl C 36 except that when disorder is detected, a message is written to stderr 37 indicating the location of the disorder. 38 .It Fl d 39 Skip non-whitespace and non-alphanumeric characters. 40 .It Fl f 41 Ignore letter case when sorting. 42 .It FL i 43 Skip non-printable characters. 44 .It Fl k Ar key 45 Specify a key definition of the form 46 .Sm off 47 .Sy S 48 .No [. 49 .Sy s 50 .No ][ 51 .Sy f 52 .No ][, 53 .Sy E 54 .No [. 55 .Sy e 56 .No ][ 57 .Sy f 58 .No ]] 59 .Sm on 60 where 61 .Sy S , s , E 62 and 63 .Sy e 64 are the starting column, starting character in that column, ending column and 65 the ending character of that column respectively.
