 #### Task1 Introduction
+本部分主要介绍一些命令的参数,介绍copy和move命令,以及访问文件和文件夹的方式等.
 #### Task2 Accessing Your Linux Machine Using SSH (Deploy)
+在Part1中我们可以通过浏览器连接到Linux机器上,这是因为我们使用的是SSH进行远程登录.
+**What is SSH & how Does it Work?**
+SSH:Secure Shell是一个协议,用于将两台设备间的通信加密.
+**Deploying Your Linux Machine**
+布置你的Linux机器,直接点击Start Machine按钮即可
+**Deploying the TryHackMe Attackbox**
+这个按钮在整个网页的最上方,点击Start AttackBox即可
+**Using SSH to Login to your Linux Machine**
+我们需要获得远程设备的IP地址,以及正确的登录凭证.这里IP/PW分别是tryhackme,tryhackme
+所以对应的登录指令为:
+<konsole root>
+root@ip-10-10-12-38:~# ssh [email protected]
+The authenticity of host '10.10.37.165 (10.10.37.165)' can't be established.
+ECDSA key fingerprint is SHA256:c/FrwCJJWUnNtf5/6wsQvZ0PM618AoDIbP9CJ465Kgk.
+Are you sure you want to continue connecting (yes/no)? yes
+Warning: Permanently added '10.10.37.165' (ECDSA) to the list of known hosts.

 #### Task3 Introduction to Flags and Switches
+每条命令都带有一些参数,比如ls命令,它用于列表所有当前目录的文件和文件夹.
+如果后面加-a(是-all的缩写),会增加隐藏文件的显示.对任意命令后面加--help可以获取关于该命令的帮助.提供所有相关参数和解释说明.
+<konsole>
+tryhackme@linux2:~$ ls --help
+Usage: ls [OPTION]... [FILE]...
+List information about the FILEs (the current directory by default).
+Sort entries alphabetically if none of -cftuvSUX nor --sort is specified.
+Mandatory arguments to long options are mandatory for short options too.
+  -a, --all                  do not ignore entries starting with .
+  -A, --almost-all           do not list implied . and ..
+      --author               with -l, print the author of each file
+  -b, --escape               print C-style escapes for nongraphic characters
+      --block-size=SIZE      with -l, scale sizes by SIZE when printing them;
+                               e.g., '--block-size=M'; see SIZE format below
+  -B, --ignore-backups       do not list implied entries ending with ~
+  -c                         with -lt: sort by, and show, ctime (time of last
+                               modification of file status information);
+                               with -l: show ctime and sort by name;
+                               otherwise: sort by ctime, newest first
+  -C                         list entries by columns
+      --color[=WHEN]         colorize the output; WHEN can be 'always' (default
+                               if omitted), 'auto', or 'never'; more info below
+  -d, --directory            list directories themselves, not their contents
+  -D, --dired                generate output designed for Emacs' dired mode
+  -f                         do not sort, enable -aU, disable -ls --color
+  -F, --classify             append indicator (one of */=>@|) to entries
+      --file-type            likewise, except do not append '*'
+      --format=WORD          across -x, commas -m, horizontal -x, long -l,
+                               single-column -1, verbose -l, vertical -C
+      --full-time            like -l --time-style=full-iso
+</konsole>
+查询命令还可以使用Man(ual)页面,除了Linux设备自带,网上也可以查.https://linux.die.net/man/
+比如man ls表示显示ls的命令说明.
+命令说明可能会很长,可以使用方向键进行上下滚动,在命令后添加-h可以得到人类易读的版本.
+:question: What directional arrow key would we use to navigate down the manual page?
+<WRAP spoiler>down</WRAP>
+:question: What flag would we use to display the output in a "human-readable" way?
+<WRAP spoiler>-h</WRAP>
