Hello World 
I want to create a conditional symbolic link in Solaris 10 so that if one destination becomes unavailable it should automatically point to another destination.
e.g. /dump/abc is destination.
/export/home/abc contains a copy of it
symbolic link should be /abc --> /dump/abc AND IF it's unavailable point to /export/home/abc
How can we do it in Solaris 10?
symbolic links are static, period.
This is a waste of cpu time but, add this to your root crontab
* * * * * /path/to/myscript.sh
myscript.sh:
[ -f /dump/abc ] && exit
unlink /dump/abc
ln -s /export/home/abc /dump/abc
Conditional symbolic links were part of some ancient unix flavors, like Sinix or Dynix in the early 90ies. The only condition they could implement was the universe a process was running in. Depending on that, the link pointed to different locations. But that is history now, conditional symbolic links are extinct.
