wc

NAME

wc – word, line, character, and byte count

SYNOPSIS

wc [-clmw] [file …]

DESCRIPTION

The wc utility displays the number of lines, words, and bytes contained in each input file, or standard input (if no file is specified) to the standard output. A line is defined as a string of characters delimited by a character. Characters beyond the final character will not be included in the line count.

A word is defined as a string of characters delimited by white space characters. White space characters are the set of characters for which the iswspace(3) function returns true. If more than one input file is specified, a line of cumulative counts for all the files is displayed on a separate line after the output for the last file.

The following options are available:

$ userExists=`cat /etc/passwd | grep looker | wc -l`
