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
60e58245f7STim J. Robbins.Xr iswspace 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:

1189b50d902SRodney W. GrimesHistorically, the
1198c85cce7SPhilippe Charnier.Nm
1209b50d902SRodney W. Grimesutility was documented to define a word as a ``maximal string of
1219b50d902SRodney W. Grimescharacters delimited by <space>, <tab> or <newline> characters''.
1229b50d902SRodney W. GrimesThe implementation, however, didn't handle non-printing characters
123557b7fa1SRuslan Ermilovcorrectly so that
1244438d91eSRuslan Ermilov.Dq Li "  ^D^E  "
1254438d91eSRuslan Ermilovcounted as 6 spaces, while
1264438d91eSRuslan Ermilov.Dq Li foo^D^Ebar
1279b50d902SRodney W. Grimescounted as 8 characters.

1329b50d902SRodney W. Grimeswith the documentation.
