Check Directory Existence Script

Create a Bash script named directory_exist.sh that prompts the user to enter a directory name. The script should then check if the directory already exists in the current location. If the directory exists, the script should print "Directory exist". If the directory does not exist, the script should create the directory and print "Directory created".

Requirements

The script should be named ~/project/directory_exist.sh.

The script should prompt the user to enter a directory name.

The script should check if the directory already exists in the current location using the -d option.

If the directory exists, the script should print "Directory exist".

If the directory does not exist, the script should create the directory using the mkdir command.

The script should print "Directory created" after creating the directory.

Example

To run the script, use the following command:

bash directory_exist.sh

Output:

Enter directory name new_directory Directory created
