【轉】linux建立軟連結

標籤：des   style   blog   http   color   使用   os   io   

執行個體：ln -s /home/gamestat    /gamestat

 

linux下的軟連結類似於windows下的捷徑

 

ln -s a b 中的 a 就是源檔案，b是連結檔案名稱,其作用是當進入b目錄，實際上是連結進入了a目錄

如上面的樣本，當我們執行命令   cd /gamestat/的時候  實際上是進入了 /home/gamestat/

 

值得注意的是執行命令的時候,應該是a目錄已經建立，目錄b沒有建立。我最開始操作的是也把b目錄給建立了，結果就不對了

 

刪除軟連結：

   rm -rf  b  注意不是rm -rf  b/

 

ln  a b 是建立永久連結

建立連結的使用方法如下：

 

 

[[email protected]_YQ_64_79 /]# 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.

When creating hard links, each TARGET must exist.

 

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

  -n, --no-dereference        treat destination that is a symlink to a

                                directory as if it were a normal file

  -i, --interactive           prompt whether to remove destinations

  -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

  -v, --verbose               print name of each file before linking

      --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
