You also need to be away that referring to positional parameter $25 will usually end up being interpreted as ${2}5, i.e. the value of parameter two, followed by the literal value 5.

Someone in their wisdom here managed to code scripts that look like this:-
Code:
date_req=$22013

The idea being that the month is passed in as positional parameter 2 and the year is appended. Apart from looking awful, of course we then ended up editing the script each year - oh, and the year was not necessarily the calender year that the process was running in either.

It works for us (very badly and will be replaced soon) but you might get very confused by the use of:-
Code:
title=$25
echo $title

.... giving you the output gM5

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).
