linux建立软链接

发布时间:2022-11-15 10:26:19 所属栏目:Linux 来源:
导读:  实例:ln -s /home/gamestat /gamestat

  linux下的软链接类似于windows下的快捷方式

  ln -s a b 中的 a 就是源文件,b是链接文件名,其作用是当进入b目录,实际上是链接进入了a目录

  如上面
  实例:ln -s /home/gamestat /gamestat
 
  linux下的软链接类似于windows下的快捷方式
 
  ln -s a b 中的 a 就是源文件,b是链接文件名,其作用是当进入b目录,实际上是链接进入了a目录
 
  如上面的示例linux软链接,当我们执行命令 cd /gamestat/的时候 实际上是进入了 /home/gamestat/
 
  值得注意的是执行命令的时候,应该是a目录已经建立,目录b没有建立。我最开始操作的是也把b目录给建立了,结果就不对了
 
  删除软链接:
 
  rm -rf b 注意不是rm -rf b/
 
  1
 
  ln a b 是建立硬链接
 
  举例:
 
  cd test-sqlserver/
 
  593 ll
 
  594 ldd Consumer
 
  595 ll /lib64 |grep libodbc
 
  596 ln -s /usr/local/lib/libodbc.so.1 libodbc.so.2
 
  建立链接的使用方法如下:
 
  [root@WEB_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
 
  -blike --backup but does not accept an argument
 
  -d, -F, --directoryallow the superuser to attempt to hard link
 
  directories (note: will probably fail due to
 
  system restrictions, even for the superuser)
 
  -f, --forceremove existing destination files
 
  -n, --no-dereferencetreat destination that is a symlink to a
 
  directory as if it were a normal file
 
  -i, --interactiveprompt whether to remove destinations
 
  -s, --symbolicmake symbolic links instead of hard links
 
  -S, --suffix=SUFFIXoverride 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, --verboseprint name of each file before linking
 
  --helpdisplay 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, offnever make backups (even if --backup is given)
 
  numbered, tmake numbered backups
 
  existing, nil numbered if numbered backups exist, simple otherwise
 
  simple, never always make simple backup
