Please look at using the command ln -s <directory> to <target directory> First create the directory you want for all the logs to go into, then creates the soft t link. Example:
ln -s Spirent SpirentTestCenter_logs Once completed, issue the command ls -al this will show "lrwxrwxrwx 1 <user> <user> <date time> Spirent -> SpirentTestCenter_logs"
If you do this in another directory not owned by you make sure you are a member of a shared group with group read/write permissions.
For more information please do a Man ln in a linux or Solaris environment
