Slight change.
Within "ksh" this should catch virtually every way of invoking the script (including ./scriptname and through $PATH ) and return an absolute path to the script.

Code:

whence -p "${0}"

However if the script is invoked with a path containing "." or ".." the result of the whence still contains those characters.

Finding a clean path to the script itself involves cleaning up the result of "whence".
One tortuous way is to:
1) Find the inode number of the script (extract from "ls -id").
2) User "dirname" to extract the path to the script,
"cd" to the directory containing the script,
and then store the result of "pwd -P".
The "-P" switch to "pwd" eliminates the effect of links.
The "pwd" also eliminates "." and ".." from the middle of the directory name.
3) Finally use "find" from the stored "pwd -P" with -xdev and -inum switches
to find the raw path to the script.

There has to be a better way!

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
       directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script,  service  passes  COMMAND and OPTIONS it to the init script unmodified.  All scripts should support at least the start and
       stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the  start
       command.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
