[solved] Script creation (how to include options in the script)
Hi guys i have written a script which takes the options given to him and execute itself accordingly.
for example
if a script name is doctortux then executing doctortux without option should made doctortux to be executed in automatic mode i.e. doctortux -a
or if a doctortux is needed to run in interactive mode we need to specify -i option.

To simulate above conditions i m using following code.
Is it the best practice to achieve the above mentioned goal?
Code:
if [ -z "$1" ] || [ "$1" == "-a" ]
then
echo "________________________________________________________________"
echo "Mode:Automatic use doctortux -i for Interactive mode"
MODE="Automatic"
echo "________________________________________________________________"
else
if [ ! -z "$1" ]
then
if [ "$1" ==  "-i" ]
then
echo "________________________________________________________________"
echo "Interactive mode selected:(Work in progress)"
MODE="Interactive"
echo "________________________________________________________________"
else
echo "$1 is not a Valid Option.Exiting from script.."
exit 1
fi
fi
fi

The above code is modified as you said .However i have some doubt to be asked.
1)How would i consider automatic mode when no option is provided with the script name?
2)why "/usr/local/sbin/doctortuxv1: illegal option -- f" illegal option is said when i have given -f?

Code:
while getopts ai option
do
case "$option" in
a) echo "Automatic Mode Selected";;
i) echo "Interacive Mode Selected";;
[?]) echo "Please select proper option";;
esac
done

output:

Code:
# doctortuxv1 -a
Automatic Mode Selected
# doctortuxv1 -i
Interacive Mode Selected
# doctortuxv1 -f
/usr/local/sbin/doctortuxv1: illegal option -- f
Please select proper option
# doctortuxv1

Code:
#!/bin/bash

if [ $# -eq 0 ]
then
  echo "Automatic Mode Selected"
else
  while getopts ai option 2>/dev/null
  do
    case "$option" in
      a) echo "Automatic Mode Selected";;
      i) echo "Interacive Mode Selected";;
      ?) echo "Please select proper option";;
    esac
  done
fi

exit 0
#finis

Code:
[house@leonov] bash code.bash -a
Automatic Mode Selected
[house@leonov] bash code.bash -i
Interacive Mode Selected
[house@leonov] bash code.bash -f
Please select proper option
[house@leonov] bash code.bash
Automatic Mode Selected
