wc命令用来打印文件的文本行数、单词数、字节数等(print the number of newlines, words, and bytes in files)。在Windows的Word中有个“字数统计”的工具,可以帮我们把选中范围的字数、字符数统计出来。Linux下的wc命令可以实现这个功能。使用vi打开文件的时候,底下的信息也会显示行数和字节数。

As you can see in this example using the command od showing the bytes, it prints the newline: $ echo foo | od -c -b 0000000 f o o \n 146 157 157 012 0000004 So in this case, wc -c as well as wc -m is counting the newline. Without the newline: $ echo -n foo | od...
