[KLUG Members] calling functions from the shell

[bill]

If I create the following file and mark it executable how would I call the
function?

#!/bin/bash

         BACKDIR= /backup
         WINCMD= /usr/bin/smbclient

         function CopyWinHost(){

         # tars and gzips "windows shares" to a local directory using samba's
         # smbclient
         # argument 1 is the remote host window's host name
         # argument 2 is the share name to be backed up

            echo $1,$2,$3
            REMOTE= $1
            SHARE= $2
            DEST= $3

          # create a tarred gzip file using samba to copy direct from a
          # windows pc
          # 12345 is a password.  Needs some password even if not defined on
          # remote system
            $WINCMD \\\\$REMOTE\\$SHARE 12345 -Tc -|gzip > $DEST
            echo `date`": Done backing up "$REMOTE" to "$DEST
            echo
         }
