cmd常用命令

直接搜索栏输入CMD后（不要立即回车进入），按住CTRL+SHIFT+ENTER键可直接进入管理员模式命令行。
notepad "%systemroot%/system32/drivers/etc/hosts" cmd 打开 hosts

网络DNS修复

1.检查配置是否由于dns,ping www.baidu.com,如果出现是dns域名解析错误，就是dns的问题
2. 配置dns,检查是否配置好，可以ping dns
3. 刷新dns 缓存ipconfig -flushdns,需要等待2-3分钟
4. 如果没有解决就是ips问题输入命名（管理员）netsh winsock reset catalog
5. 重启电脑

用命令行打开文件

在运行中输入命令：

d:\test..\

或者在命令提示符里面输入:

explorer c:\files\(绝对路径)
explorer files (相对路径)
start d:\test..\
explorer和start的区别是
start必须使用绝对路径，
explorer既可以使用绝对路径也可使用相对路径。

即可以打开指定的文件夹，并可以在文件夹内操作，和一般文件夹一样;

git bash 基于win10

创建软连接,note：target 必须是绝对路径，且软连接是linkfile /d/gitlab 不存在这一点与linux中有些不同

 ln -s -T /d/Projects/RemoteHub/gitlab/ /d/gitlab

zutnlp@zutnlp:/home$ ln --help
Usage: ln [OPTION]... [-T] TARGET LINK_NAME   (1st form)
  or:  ln [OPTION]... TARGET                  (2nd form)
  or:  ln [OPTION]... TARGET... DIRECTORY     (3rd form)
  or:  ln [OPTION]... -t DIRECTORY TARGET...  (4th form)
In the 1st form, create a link to TARGET with the name LINK_NAME.
In the 2nd form, create a link to TARGET in the current directory.
In the 3rd and 4th forms, create links to each TARGET in DIRECTORY.
Create hard links by default, symbolic links with --symbolic.
By default, each destination (name of new link) should not already exist.
When creating hard links, each TARGET must exist.  Symbolic links
can hold arbitrary text; if later resolved, a relative link is
interpreted in relation to its parent directory.

Mandatory arguments to long options are mandatory for short options too.
      --backup[=CONTROL]      make a backup of each existing destination file
  -b                          like --backup but does not accept an argument
  -d, -F, --directory         allow the superuser to attempt to hard link
                                directories (note: will probably fail due to
                                system restrictions, even for the superuser)
  -f, --force                 remove existing destination files
  -i, --interactive           prompt whether to remove destinations
  -L, --logical               dereference TARGETs that are symbolic links
  -n, --no-dereference        treat LINK_NAME as a normal file if
                                it is a symbolic link to a directory
  -P, --physical              make hard links directly to symbolic links
  -r, --relative              create symbolic links relative to link location
  -s, --symbolic              make symbolic links instead of hard links
  -S, --suffix=SUFFIX         override the usual backup suffix
  -t, --target-directory=DIRECTORY  specify the DIRECTORY in which to create
                                the links
  -T, --no-target-directory   treat LINK_NAME as a normal file always
  -v, --verbose               print name of each linked file
      --help     display this help and exit
      --version  output version information and exit

The backup suffix is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control method may be selected via the --backup option or through
the VERSION_CONTROL environment variable.  Here are the values:

  none, off       never make backups (even if --backup is given)
  numbered, t     make numbered backups
  existing, nil   numbered if numbered backups exist, simple otherwise
  simple, never   always make simple backups

Using -s ignores -L and -P.  Otherwise, the last option specified controls
behavior when a TARGET is a symbolic link, defaulting to -P.
