Did you create the tar file?
If so, why would you name a directory
using a "$"? If not, tell the creator
to fix this. I suspect there is a similar
problem accessing that directory on the remote.

Having said that you should be able to
access it as follows:

cd /arcagent/UAGENT/reloc/\$UAGENT_HOME

...but personally, I hate it when people
name directories like this "on purpose"
