題目：I found two files in a secret room. They look like jumbled letters with no patterns. I mean look at it! file1 is identical to file2, right?
下載file1和file2的檔案在這裡：

file1和file2都是兩個密密麻麻的文字檔案．
他問說file1和file2 是兩個完全相同的檔案嗎？
這邊使用的是cmp指令：用來比較兩個文件內容是否相同
cmp的參數運用方式如下
Mandatory arguments to long options are mandatory for short options too.-b, –print-bytes print differing bytes-i, –ignore-initial=SKIP skip first SKIP bytes of both inputs-l, –verbose output byte numbers and differing byte values-n, –bytes=LIMIT compare at most LIMIT bytes-s, –quiet, –silent suppress all normal output–help display this help and exit
