Also, there is a PPA for Debian-based systems such as Ubuntu, Linux Mint.
$ sudo add-apt-repository ppa:navanchauhan/bash-snippets $ sudo apt update $ sudo apt install bash-snippets
An active Internet connection is required to use these tools. The usage is fairly simple. Let us see how to use some of these scripts. I assume you have installed all scripts.
1. Currency – Currency Converter
This script converts the currency based on realtime exchange rates. Enter the base currency code and the currency to exchange to, and the amount being exchanged one by one as shown below.
$ currency What is the base currency: INR What currency to exchange to: USD What is the amount being exchanged: 10 ========================= | INR to USD | Rate: 0.015495 | INR: 10 | USD: .154950 =========================
You can also pass all arguments in a single command as shown below.
$ currency INR USD 10
Refer the following screenshot.
2. Stocks – Display stock price details
If you want to check a stock price details, mention the stock item as shown below.
$ stocks Intel INTC stock info ============================================= | Exchange Name: NASDAQ | Latest Price: 34.2500 | Close (Previous Trading Day): 34.2500 | Price Change: 0.0000 | Price Change Percentage: 0.00% | Last Updated: Jul 12, 4:00PM EDT =============================================

4. Crypt – Encrypt and Decrypt files
This script is a wrapper for openssl that allows you to encrypt and decrypt files quickly and easily.
To encrypt a file, use the following command:
$ crypt -e [original file] [encrypted file]
For example, the following command will encrypt a file called ostechnix.txt, and save it as encrypt_ostechnix.txt in the current working directory.
$ crypt -e ostechnix.txt encrypt_ostechnix.txt
Enter the password for the file twice.
Encrypting ostechnix.txt... enter aes-256-cbc encryption password: Verifying - enter aes-256-cbc encryption password: Successfully encrypted
The above command will encrypt the given file using AES 256 level encryption. The password will not be saved in plain text. You can encrypt .pdf, .txt, .docx, .doc, .png, .jpeg type files.
To decrypt the file, use the following command:
$ crypt -d [encrypted file] [output file]
$ crypt -d encrypt_ostechnix.txt ostechnix.txt
Enter the password to decrypt.
Decrypting encrypt_ostechnix.txt... enter aes-256-cbc decryption password: Successfully decrypted
5. Movies – Find Movie details
Using this script, you can find a movie details.
