How to run Bourne shell script on Unix.

I wrote a simple Bourne shell script to test, but I don't know how to run it on Unix system.  Thanks for help. Mitsuru

#!  /bin/sh
#  SHOWINFO: Bourne shell acript to display an information file

#  If the information file exists, display its contents.
#  Otherwise, if the files does not exist, but if an older version exists, display the older version.  
#  If neither file exists, display an error message
     if   [-f  info]
     then
          echo "This information file has been found.";
          more info
     elif   [-f  info.old]
     then
          echo "Only the old information file was found.";
          more info.old
     else
          echo "The information file was not found."
     fi
