You could try something like this, using pwd and ls -l to determine the absolute pathname:

Code:

file=$(cd -P -- "${0%/*}" 2>/dev/null; pwd -P)/${0##*/}  # get the physical path name of the file that is being specified
while :                                                  # iterate through symbolic links to arrive at the actual directory
do
  ls=$(/bin/ls -l "$file") 
  case $ls in
    l*) file=${file%/*}/${ls##*-> } ;;                   # if the file is a symbolic link then follow it, by replacing
    *)  break ;;                                         # the file name with what the link points to, if not then break the loop
  esac
done
actualdir=${file%/*}

You can never force this of course, since one could copy the script and make an adjustment of the variable, but it may help to make users aware....

On Linux one could also use readlink, but this is a more general approach, which should also work on most Unix platforms...

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
