499b50d902SRodney W. GrimesThe
508c85cce7SPhilippe Charnier.Nm
519b50d902SRodney W. Grimesutility displays the number of lines, words, and bytes contained in each
529b50d902SRodney W. Grimesinput
539b50d902SRodney W. Grimes.Ar file
549b50d902SRodney W. Grimes(or standard input, by default) to the standard output.
559b50d902SRodney W. GrimesA line is defined as a string of characters delimited by a <newline>
569b50d902SRodney W. Grimescharacter,
579b50d902SRodney W. Grimesand a word is defined as a string of characters delimited by white space
589b50d902SRodney W. Grimescharacters.
599b50d902SRodney W. GrimesWhite space characters are the set of characters for which the
609b50d902SRodney W. Grimes.Xr isspace 3
619b50d902SRodney W. Grimesfunction returns true.
629b50d902SRodney W. GrimesIf more than one input file is specified, a line of cumulative counts
639b50d902SRodney W. Grimesfor all the files is displayed on a separate line after the output for
649b50d902SRodney W. Grimesthe last file.
659b50d902SRodney W. Grimes.Pp
669b50d902SRodney W. GrimesThe following options are available:

699b50d902SRodney W. GrimesThe number of bytes in each input file
709b50d902SRodney W. Grimesis written to the standard output.
719b50d902SRodney W. Grimes.It Fl l
729b50d902SRodney W. GrimesThe number of lines in each input file
739b50d902SRodney W. Grimesis written to the standard output.
749b50d902SRodney W. Grimes.It Fl w
759b50d902SRodney W. GrimesThe number of words in each input file
769b50d902SRodney W. Grimesis written to the standard output.

799b50d902SRodney W. GrimesWhen an option is specified,
808c85cce7SPhilippe Charnier.Nm
819b50d902SRodney W. Grimesonly reports the information requested by that option.
829b50d902SRodney W. GrimesThe default action is equivalent to specifying all of the flags.
839b50d902SRodney W. Grimes.Pp
849b50d902SRodney W. GrimesIf no files are specified, the standard input is used and no
859b50d902SRodney W. Grimesfile name is displayed.

879b50d902SRodney W. GrimesThe
888c85cce7SPhilippe Charnier.Nm
899b50d902SRodney W. Grimesutility exits 0 on success, and >0 if an error occurs.

929b50d902SRodney W. Grimes.Sh COMPATIBILITY
939b50d902SRodney W. GrimesHistorically, the
948c85cce7SPhilippe Charnier.Nm
959b50d902SRodney W. Grimesutility was documented to define a word as a ``maximal string of
969b50d902SRodney W. Grimescharacters delimited by <space>, <tab> or <newline> characters''.
979b50d902SRodney W. GrimesThe implementation, however, didn't handle non-printing characters
989b50d902SRodney W. Grimescorrectly so that ``  ^D^E  '' counted as 6 spaces, while ``foo^D^Ebar''
999b50d902SRodney W. Grimescounted as 8 characters.
1009b50d902SRodney W. Grimes4BSD systems after 4.3BSD modified the implementation to be consistent
1019b50d902SRodney W. Grimeswith the documentation.
1029b50d902SRodney W. GrimesThis implementation defines a ``word'' in terms of the
1039b50d902SRodney W. Grimes.Xr isspace 3
1049b50d902SRodney W. Grimesfunction, as required by
1059b50d902SRodney W. Grimes.St -p1003.2 .
1069b50d902SRodney W. Grimes.Sh STANDARDS
1079b50d902SRodney W. GrimesThe
1088c85cce7SPhilippe Charnier.Nm
1099b50d902SRodney W. Grimesfunction conforms to
