wc(1)
NAME
wc − word count
SYNOPSIS
wc [−lwc] [names]
DESCRIPTION
wc counts lines, words, and characters in the named files, or in the standard input if no names appear. It also keeps a total count for all named files. A word is a maximal string of characters delimited by spaces, tabs, or new-lines.
The options l, w, and c may be used in any combination to specify that a subset of lines, words, and characters are to be reported. The default is −lwc.
When names are specified on the command line, they will be printed along with the counts.
