Top Forums UNIX for Advanced & Expert Users link and unlink , urgently... Post 12019 by Perderabo on Monday 17th of December 2001 11:06:42 AM

I doubt that there is any reasonable way to do this. The inode is a mount point, so the unlink system call can't touch it. I would just rename to "..." and leave it alone. It isn't causing much trouble. It's like a bullet too close to a spine...it's too risky to attempt removal.

One thing that might work would be to try nfs. Export or share the root volume. And then use nfs to "remotely" mount a second copy of it. Then try the unlink via nfs. This really should fail, but with nfs, you never know.

And the final option would be editing the raw device. You may have a program called fsdb for this purpose.

set_link

set link(1m)															      set link(1m)

NAME

       set link - Changes the value of a modifiable, single-valued attribute of a soft link

SYNOPSIS

       cdscp set link link-name attribute-name = attribute-value

ARGUMENTS

       The  full  name	of  the  soft link.  The name of the attribute to be modified.	Specify only one attribute at a time.  See Description for
       valid attribute names.  The value of a particular attribute.

DESCRIPTION

       The set link command changes the value of a modifiable, single-valued attribute of a soft link.	The following are valid attributes: Speci-
       fies the full name of the directory, object entry, or other soft link to which the soft link points.  Specifies a timeout value after which
       the soft link is either checked or deleted.  The timeout value contains both an expiration time and an  extension  time.  If  a	soft  link
       expires and its target entry is deleted, the soft link is deleted. If the soft link still points to an existing entry, its life is extended
       by the expiration time. Specify expiration-time in the format yyyy-mm-dd-hh:mm:ss (year-month-day-hour:minute:second).  Specify	extension-
       time in the format ddd-hh:mm:ss (day-hour:minute:second).

   Privilege Required
       You must have write permission to the soft link.

NOTE

       This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

EXAMPLE

       The  following  command	redirects a soft link named /.:/admin/work_disk from its current destination name, /.:/admin/work_disk01, to a new
       destination name, /.:/admin/work_disk03.  cdscp> set link /.:/admin/work_disk CDS_LinkTarget = /.:/admin/work_disk03
