我试图在 Solaris 操作系统上复制链接，但发现它不是简单地复制链接，而是复制链接指向的目录/文件的全部内容？这在 AIX、HP-UX、Linux 等其他操作系统中是没有的。

这是 Solaris 操作系统的正常行为吗？

Charlie 很接近，您需要 -L、-H 或 -P 标志以及 -R > 标志(可能只是 -R -P)。 chmod(1) 和 chgrp(1) 也存在类似的标志。我粘贴了下面的手册页的摘录。

示例:

$ touch x
$ ln -s x y 
$ ls -l x y 
-rw-r--r--   1 mjc      mjc            0 Mar 31 18:58 x
lrwxrwxrwx   1 mjc      mjc            1 Mar 31 18:58 y -> x
$ cp -R -P y z
$ ls -l z
lrwxrwxrwx   1 mjc      mjc            1 Mar 31 18:58 z -> x
$ 

或者，默认情况下，普通的旧 tar 会愉快地使用符号链接(symbolic link)，甚至是 Solaris 附带的古老版本:

tar -cf foo | ( cd bar && tar -xf - )

(其中 foo 是符号链接(symbolic link)或包含符号链接(symbolic link)的目录)。

 /usr/bin/cp -r | -R [-H | -L | -P] [-fip@] source_dir... target

 ...

 -H    Takes actions based on the type and  contents  of  the
       file  referenced  by  any symbolic link specified as a
       source_file operand.

       If the source_file operand is a symbolic link, then cp
       copies  the  file  referenced by the symbolic link for
       the source_file  operand.  All  other  symbolic  links
       encountered  during  traversal of a file hierarchy are
       preserved.


 -L    Takes actions based on the type and  contents  of  the
       file  referenced  by  any symbolic link specified as a
       source_file operand or any symbolic links  encountered
       during traversal of a file hierarchy.

       Copies files referenced by  symbolic  links.  Symbolic
       links encountered during traversal of a file hierarchy
       are not preserved.


 -P    Takes actions on any  symbolic  link  specified  as  a
       source_file  operand  or any symbolic link encountered
       during traversal of a file hierarchy.

       Copies symbolic links. Symbolic links encountered dur-
       ing traversal of a file hierarchy are preserved.
