With no FILE, or when FILE is -, read standard input.

The options below may be used to select which counts are printed, always in the following order: newline, word, character, byte, maximum line length.

-c, --bytes

print the byte counts

-m, --chars

print the character counts

-l, --lines

print the newline counts

--files0-from=F

read input from the files specified by NUL-terminated names in file F; If F is - then read names from standard input

-L, --max-line-length

print the maximum display width

-w, --words

print the word counts
