With help of tips from 'here and there' , I just created a simple script to
1. declare one array and some global variables
2. read the schema names from user (user input) and want2proceed flag
3. if user want to proceed , keep reading user input schema name
4. exit the loop if user doesn't want to proceed or it reaches Maximum schema numbers (3)
5 assigns the arrays to global variable only if arrays are not null
This work fine up to this stage . But wants to know any thing could be done to optimize the script or to make the script compact.
And Now I am planning to call other shell scripts with parameter as array value. Its template is also given in the above script .
The basic questions are , Is there any ..
1. change could be done to optimize the script or to make it compact ?
2. function to change the case of input schema name ?
3. technique to validate user input flag (y/n)
4. make the echo and input in the same line.
