A script is running from an unknown location in the system.How we can find its exact location.We only know the name of the script.

lsof will probably show the full path of the script for you.

You can also use locate command to locate the full path with file name of your file.
Example-

Try any/all of

locate
fuser
lsof
find
ps -auxwww

lsof -r 1 <script name>

The question is similar to whether a running script can determine its own location. It is not possible in all cases. More at Greg's WIKI.
