Handling parameters in Shell Functions
Hi,

Please help me with the below situation where I have to handle the parameters passed to a function in a unique way.

Below is the code, which I am trying to execute. I basically want to pass the parameter to a function, where I am trying to get user input into array(s). I want to name the array(s) based on the parameter. Please help me do it!!

Code:
 
#! /bin/sh
 
#GET_TABLE FUNCTION
get_table()
{
  i=0;
 
  set -A $1_file_array NULL;
  set -A $1_db_array NULL;
  set -A $1_table_array NULL;
 
  echo " Please enter tables that are affected in '<DBName>.<Tablename(s)>' format      :"
 
  while read file
  do
    if [ ${#file} -gt 0 ]; then
      $1_file_array[$i]=$file
      $1_db_array[$i]=${file%.*}
      $1_table_array[$i]=${file#*.}
      i=`expr $i + 1`
    fi
  done
  $1_count=${#$1_file_array[@]}
  return $1_count
}
 
# CALL FUNCTION GET_TABLE WITH 'SRC' AS PARM
get_table src
 
# DISPLAY THE LOADED ARRAY
j=0;
src_count=$?
while [ $j -lt src_count ]
do
# BELOW ARE THE ARRAY NAMES I WISH TO SEE
    echo "File: ${src_file_array[$j]}"
    echo "DB: ${src_db_array[$j]}"
    echo "Table: ${src_table_array[$j]}"
    j=`expr $j + 1`
done

Please let me know for any questions.

Thanks
Bharath

cpanplus::shell

CPANPLUS::Shell(3)					User Contributed Perl Documentation					CPANPLUS::Shell(3)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
