Linux wc指令:檔案行數、字元數統計指令
[email protected]_u1604:~$ wc --help
用法：wc [選項]... [檔案]...
或：wc [選項]... --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.
如果沒有指定檔案，或者檔案為"-"，則從标準輸入讀取。
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
