I found the solution of this :
for information to create new link to far directory is :
ln -s (source) (destination) ...just this ..
example
you have one directory name vantrix contain 7 txt files..
vantrix path is : /opt/spotxde/software/var/logs/vantrix
to make one link in new directory ..do this .
1- create new directory
mkdir test
2- create link to vantrix in test directory
the link command is :
ln -s /opt/spotxde/software/var/logs/vantrix/ /test/ ....just
3- check now test directory ..you will find vantrix directory in it .
thansk for all ..
