Linux wc命令详解


wc [OPTION]… [FILE]…
wc [OPTION]… –files0-from=F


       Print  newline,  word,  and byte counts for each FILE, and a total line if more than one FILE is specified.  A
       word is a non-zero-length sequence of characters delimited by white space.

       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

              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

       --help display this help and exit
