9b50d902SRodney W. GrimesThe

9b50d902SRodney W. Grimesutility displays the number of lines, words, and bytes contained in each
9b50d902SRodney W. Grimesinput
9b50d902SRodney W. Grimes.Ar file
9b50d902SRodney W. Grimes(or standard input, by default) to the standard output.
9b50d902SRodney W. GrimesA line is defined as a string of characters delimited by a <newline>
9b50d902SRodney W. Grimescharacter,
9b50d902SRodney W. Grimesand a word is defined as a string of characters delimited by white space
9b50d902SRodney W. Grimescharacters.
9b50d902SRodney W. GrimesWhite space characters are the set of characters for which the
9b50d902SRodney W. Grimes.Xr isspace 3
9b50d902SRodney W. Grimesfunction returns true.
9b50d902SRodney W. GrimesIf more than one input file is specified, a line of cumulative counts
9b50d902SRodney W. Grimesfor all the files is displayed on a separate line after the output for
9b50d902SRodney W. Grimesthe last file.

9b50d902SRodney W. GrimesThe number of bytes in each input file
9b50d902SRodney W. Grimesis written to the standard output.

9b50d902SRodney W. GrimesThe number of lines in each input file

9b50d902SRodney W. GrimesThe number of words in each input file
9b50d902SRodney W. Grimesis written to the standard output.

9b50d902SRodney W. GrimesWhen an option is specified,
9b50d902SRodney W. Grimes.Nm wc
9b50d902SRodney W. Grimesonly reports the information requested by that option.
9b50d902SRodney W. GrimesThe default action is equivalent to specifying all of the flags.
9b50d902SRodney W. Grimes.Pp
9b50d902SRodney W. GrimesIf no files are specified, the standard input is used and no
9b50d902SRodney W. Grimesfile name is displayed.

9b50d902SRodney W. GrimesThe
9b50d902SRodney W. Grimes.Nm wc

9b50d902SRodney W. Grimes.Sh COMPATIBILITY
9b50d902SRodney W. GrimesHistorically, the
9b50d902SRodney W. Grimes.Nm wc
9b50d902SRodney W. Grimesutility was documented to define a word as a ``maximal string of
9b50d902SRodney W. Grimescharacters delimited by <space>, <tab> or <newline> characters''.
9b50d902SRodney W. GrimesThe implementation, however, didn't handle non-printing characters
9b50d902SRodney W. Grimescorrectly so that ``  ^D^E  '' counted as 6 spaces, while ``foo^D^Ebar''
9b50d902SRodney W. Grimescounted as 8 characters.
9b50d902SRodney W. Grimes4BSD systems after 4.3BSD modified the implementation to be consistent
9b50d902SRodney W. Grimeswith the documentation.
9b50d902SRodney W. GrimesThis implementation defines a ``word'' in terms of the
9b50d902SRodney W. Grimes.Xr isspace 3
9b50d902SRodney W. Grimesfunction, as required by
9b50d902SRodney W. Grimes.St -p1003.2 .
