总结
前言
Linux是一个开源的操作系统，它的目录结构非常重要，因为它是使用Linux系统的一个基础。本文将介绍一些操作Linux系统中文件、目录的常用命令，其中有些命令在Dos中也有命令相对应（指发挥的功能类似的）。
另外有一点区别： Linux系统下命令是大小写敏感的，一般是全小写的；Dos系统下命令是不区分大小写的，命令名大小写混装都是相同的，如 cd CD cD Cd就是同一个命令。
基础命令（文件目录相关的）
cd命令
cd：切换当前工作目录。可以使用绝对路径或相对路径。
进入根目录的命令是：cd /，进入用户的home目录的命令是：cd ~。
其中，“/”、“~” 分别表示根目录和当前用户的home目录。
绝对路径方式的切换：cd /home/user/documents
相对路径方式的切换：cd ../user/documents
其中，绝对路径指从根目录起始的路径；相对路径指从当前目录起始的路径。

hann@HannYang:~$ cd --help
cd: cd [-L|[-P [-e]] [-@]] [dir]
Change the shell working directory.
Change the current directory to DIR. The default DIR is the value of the
HOME shell variable.
The variable CDPATH defines the search path for the directory containing
DIR. Alternative directory names in CDPATH are separated by a colon (:).
A null directory name is the same as the current directory. If DIR begins
with a slash (/), then CDPATH is not used.
If the directory is not found, and the shell option `cdable_vars' is set,
the word is assumed to be a variable name. If that variable has a value,
its value is used for DIR.
Options:
-L force symbolic links to be followed: resolve symbolic
links in DIR after processing instances of `..'
-P use the physical directory structure without following
symbolic links: resolve symbolic links in DIR before
processing instances of `..'
-e if the -P option is supplied, and the current working
directory cannot be determined successfully, exit with
a non-zero status
-@ on systems that support it, present a file with extended
attributes as a directory containing the file attributes
The default is to follow symbolic links, as if `-L' were specified.
`..' is processed by removing the immediately previous pathname component
back to a slash or the beginning of DIR.
Exit Status:
Returns 0 if the directory is changed, and if $PWD is set successfully when
-P is used; non-zero otherwise.【对应Dos命令】
cd 同名同功能，格式： cd 目录路径
显示当前目录名或改变当前目录。或者用长名称 chdir
CHDIR [/D] [drive:][path]
CHDIR [..]
CD [/D] [drive:][path]
CD [..]
.. 指定要改成父目录。
键入 CD drive: 显示指定驱动器中的当前目录。
不带参数只键入 CD，则显示当前驱动器和目录。
使用 /D 开关，除了改变驱动器的当前目录之外，
还可改变当前驱动器。
如果命令扩展被启用，CHDIR 会如下改变:
当前的目录字符串会被转换成使用磁盘名上的大小写。所以，
如果磁盘上的大小写如此，CD C:\TEMP 会将当前目录设为
C:\Temp。
CHDIR 命令不把空格当作分隔符，因此有可能将目录名改为一个
带有空格但不带有引号的子目录名。例如:
cd \winnt\profiles\username\programs\start menu
与下列相同:
cd "\winnt\profiles\username\programs\start menu"
在扩展停用的情况下，你必须键入以上命令。
pwd命令
pwd：显示当前工作目录的路径。例如，pwd将显示当前工作目录的完整路径。
pwd命令用于显示当前工作目录（即当前所在的目录）的绝对路径。在Linux系统中，每个用户都有自己的home目录，刚登陆系统时，所在的目录就是用户自己的home目录。
hann@HannYang:~$ pwd
/home/hann
【英文帮助】
hann@HannYang:~$ pwd --help
pwd: pwd [-LP]
Print the name of the current working directory.
Options:
-L print the value of $PWD if it names the current working
directory
-P print the physical directory, without any symbolic links
By default, `pwd' behaves as if `-L' were specified.
Exit Status:
Returns 0 unless an invalid option is given or the current directory
cannot be read.【对应Dos命令】
Dos下没有单独的pwd命令，用CD命令不加参数即可：
C:\Users\hann>CD
C:\Users\hann
C:\Users\hann>cD
C:\Users\hann
C:\Users\hann>Cd
C:\Users\hann
C:\Users\hann>cd
C:\Users\hann
ls命令
ls：显示当前或指定目录中的文件和目录列表。
ls 命令参数极其复杂，默认为短格式显示，只有文件名，详细格式可以用参数 -l ，以长格式详细显示目录中的文件和目录列表，包括文件大小、权限、所有者、修改时间等信息。
【英文帮助】
hann@HannYang:~$ 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.

-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

single-column -1, verbose -l, vertical -C
--full-time like -l --time-style=full-iso
-g like -l, but do not list owner
--group-directories-first
group directories before files;
can be augmented with a --sort option, but any
use of --sort=none (-U) disables grouping
-G, --no-group in a long listing, don't print group names
-h, --human-readable with -l and -s, print sizes like 1K 234M 2G etc.
--si likewise, but use powers of 1000 not 1024
-H, --dereference-command-line
follow symbolic links listed on the command line
--dereference-command-line-symlink-to-dir
follow each command line symbolic link
that points to a directory
--hide=PATTERN do not list implied entries matching shell PATTERN
(overridden by -a or -A)
--hyperlink[=WHEN] hyperlink file names; WHEN can be 'always'
(default if omitted), 'auto', or 'never'
--indicator-style=WORD append indicator with style WORD to entry names:
none (default), slash (-p),
file-type (--file-type), classify (-F)
-i, --inode print the index number of each file
-I, --ignore=PATTERN do not list implied entries matching shell PATTERN
-k, --kibibytes default to 1024-byte blocks for disk usage;
used only with -s and per directory totals
-l use a long listing format
-L, --dereference when showing file information for a symbolic
link, show information for the file the link
references rather than for the link itself
-m fill width with a comma separated list of entries
-n, --numeric-uid-gid like -l, but list numeric user and group IDs
-N, --literal print entry names without quoting
-o like -l, but do not list group information
-p, --indicator-style=slash
append / indicator to directories
-q, --hide-control-chars print ? instead of nongraphic characters
--show-control-chars show nongraphic characters as-is (the default,
unless program is 'ls' and output is a terminal)
-Q, --quote-name enclose entry names in double quotes
--quoting-style=WORD use quoting style WORD for entry names:
literal, locale, shell, shell-always,
shell-escape, shell-escape-always, c, escape
(overrides QUOTING_STYLE environment variable)
-r, --reverse reverse order while sorting
-R, --recursive list subdirectories recursively
-s, --size print the allocated size of each file, in blocks
-S sort by file size, largest first
--sort=WORD sort by WORD instead of name: none (-U), size (-S),
time (-t), version (-v), extension (-X)
--time=WORD with -l, show time as WORD instead of default
modification time: atime or access or use (-u);
ctime or status (-c); also use specified time
as sort key if --sort=time (newest first)
--time-style=TIME_STYLE time/date format with -l; see TIME_STYLE below
-t sort by modification time, newest first
-T, --tabsize=COLS assume tab stops at each COLS instead of 8
-u with -lt: sort by, and show, access time;
with -l: show access time and sort by name;
otherwise: sort by access time, newest first
-U do not sort; list entries in directory order
-v natural sort of (version) numbers within text
-w, --width=COLS set output width to COLS. 0 means no limit
-x list entries by lines instead of by columns
-X sort alphabetically by entry extension
-Z, --context print any security context of each file
-1 list one file per line. Avoid '\n' with -q or -b
--help display this help and exit
--version output version information and exit
The SIZE argument is an integer and optional unit (example: 10K is 10*1024).
Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).
The TIME_STYLE argument can be full-iso, long-iso, iso, locale, or +FORMAT.
FORMAT is interpreted like in date(1). If FORMAT is FORMAT1<newline>FORMAT2,
then FORMAT1 applies to non-recent files and FORMAT2 to recent files.
TIME_STYLE prefixed with 'posix-' takes effect only outside the POSIX locale.
Also the TIME_STYLE environment variable sets the default style to use.
Using color to distinguish file types is disabled both by default and
with --color=never. With --color=auto, ls emits color codes only when
standard output is connected to a terminal. The LS_COLORS environment
variable can change the settings. Use the dircolors command to set it.
Exit status:
0 if OK,
1 if minor problems (e.g., cannot access subdirectory),
2 if serious trouble (e.g., cannot access command-line argument).

-r, -R, --recursive remove directories and their contents recursively
-d, --dir remove empty directories
-v, --verbose explain what is being done
--help display this help and exit
--version output version information and exit
By default, rm does not remove directories. Use the --recursive (-r or -R)
option to remove each listed directory, too, along with all of its contents.
To remove a file whose name starts with a '-', for example '-foo',
use one of these commands:
rm -- -foo
rm ./-foo
Note that if you use rm to remove a file, it might be possible to recover
some of its contents, given sufficient expertise and/or time. For greater
assurance that the contents are truly unrecoverable, consider using shred.

[drive:][path]dirname1 指定要重命名的目录。
dirname2 指定目录的新名称。
/Y 取消确认覆盖一个现有目标文件的提示。
/-Y 对确认覆盖一个现有目标文件发出提示。
命令行开关 /Y 可以出现在 COPYCMD 环境变量中。这可以用命令行上
的 /-Y 替代。默认值是，除非 MOVE 命令是从一个批脚本内
执行的，覆盖时都发出提示。
Dos另有单独命名文件的命令 ren
重命名文件。
RENAME [drive:][path]filename1 filename2.
REN [drive:][path]filename1 filename2.
请注意，你不能为目标文件指定新的驱动器或路径。
chmod命令
chmod：更改文件或目录的权限。例如，chmod 755 file1将更改file1的权限，使其可读、可写和可执行。

hann@HannYang:~$ cd --help
cd: cd [-L|[-P [-e]] [-@]] [dir]
Change the shell working directory.
Change the current directory to DIR. The default DIR is the value of the
HOME shell variable.
The variable CDPATH defines the search path for the directory containing
DIR. Alternative directory names in CDPATH are separated by a colon (:).
A null directory name is the same as the current directory. If DIR begins
with a slash (/), then CDPATH is not used.
If the directory is not found, and the shell option `cdable_vars' is set,
the word is assumed to be a variable name. If that variable has a value,
its value is used for DIR.
Options:
-L force symbolic links to be followed: resolve symbolic
links in DIR after processing instances of `..'
-P use the physical directory structure without following
symbolic links: resolve symbolic links in DIR before
processing instances of `..'
-e if the -P option is supplied, and the current working
directory cannot be determined successfully, exit with
a non-zero status
-@ on systems that support it, present a file with extended
attributes as a directory containing the file attributes
The default is to follow symbolic links, as if `-L' were specified.
`..' is processed by removing the immediately previous pathname component
back to a slash or the beginning of DIR.
Exit Status:
Returns 0 if the directory is changed, and if $PWD is set successfully when
-P is used; non-zero otherwise.【对应Dos命令】
两边的文件系统属性不一样，只有attrib功能比较类似
显示或更改文件属性。
ATTRIB [+R | -R] [+A | -A] [+S | -S] [+H | -H] [+O | -O] [+I | -I] [+X | -X] [+P | -P] [+U | -U]
[drive:][path][filename] [/S [/D]] [/L]
+ 设置属性。
- 清除属性。
R 只读文件属性。
A 存档文件属性。
S 系统文件属性。
H 隐藏文件属性。
O 脱机属性。
I 无内容索引文件属性。
X 无清理文件属性。
V 完整性属性。
P 固定属性。
U 非固定属性。
[drive:][path][filename]
指定属性要处理的文件。
/S 处理当前文件夹及其所有子文件夹中
的匹配文件。
/D 也处理文件夹。
/L 处理符号链接和
符号链接目标的属性
总结
以上介绍的这些基础命令基本上Dos，Linux两系统都有，熟悉这些命令可以帮助用户更加方便地管理自己的文件和目录。当然还有文件查看类的命令，比如 more命令两系统都有这个命令；另外 linux 的 cat 对应 dos 的 TYPE。
总的来说，相比较还是Linux的外部命令更丰富一点，还有 find, stat, grep 等等这些功能强大的外部命令在Dos里没有相对应的命令（小众的非官方的自己编写的除外）。
