case statement in unix
Thanks robin, have modified the code and it works only if one file exists (it doesn't work in case redundant file name exists)

Have read the file testing today and written the below code based on my understanding. it works fine. but the problem var_1 and var_2 are not resetting (how do i initialize the values because it takes the already exists value)

Program Flow:
1) Get a word from user
2) check whether a file or directory exists in the given name
3) if not, display no dir or file was exists in the given name
Code:
#!/bin/sh
# Get a word from user and check whether a filename or directory exists in the same name

echo "enter a name \c"
read name

# if its a file, var_1 will have 0
var_1=`[ -f $name ];echo $?`

# if its a directory, var_2 will have 1
var_2=`[ -d $name ];echo $?`

    if [ $var_1 -eq 0  -a $var_2 -eq 1 ]
       then
         echo "Given name has both file and dir"

     elif [ $var_1 -eq 0 -a $var_2 -ne 1 ]
      then
         echo "Given name is a file"
    elif [ $var_2 -eq 1 -a $var_1 -ne 0 ]
      then
         echo "Given name is a directory"
    else
         echo "neither a file nor a dir"
fi

Can you please help me.

echo(3XCURSES)						  X/Open Curses Library Functions					    echo(3XCURSES)

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       int echo(void);

       int noecho(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.

       Upon successful completion, these functions return OK. Otherwise, they return ERR.

ERRORS

       No errors are defined.
