#! /bin/bash
i="y"
echo "Enter name of database "
read db
while [ $i = "y" ]
do
clear

echo "4.Make a dir"
echo "5.Copy a file"
echo "6.Rename file"
echo "7.Delete file"
echo "8.Edit file"
echo "9.Add e record"
echo "10.Delete data"
echo "11.Exit"
echo "Enter your choice"
read ch
case $ch in
1)echo "Enter id "
read id
grep -i "$id" $db ;;
2)echo "Current Dir is : "
pwd;;
3)echo "Directories are"
ls;;
4)echo "Enter dir name to create"
read d
mkdir $d
echo $d" Dir is created";;
5)echo "Enter filename from copy"
read f1
echo "Enter filenm2 to be copied"
read f2
#cat $f1 > $f2
cp $f1 $f2
