A Collection Of Useful BASH Scripts For Heavy Commandline Users
======
![](https://www.ostechnix.com/wp-content/uploads/2017/07/A-Collection-Of-Useful-BASH-Scripts-720x340.png)
Today, I have stumbled upon a collection of useful BASH scripts for heavy commandline users. These scripts, known as **Bash-Snippets** , might be quite helpful for those who live in Terminal all day. Want to check the weather of a place where you live? This script will do that for you. Wondering what is the Stock price? You can run the script that displays the current details of a stock. Feel bored? You can watch some youtube videos. All from commandline. You don’t need to install any heavy memory consumable GUI applications.
As of writing this, Bash-Snippets provides the following 19 useful tools:
1. **Cheat** – Linux Commands cheat sheet.
2. **Cloudup** – A tool to backup your GitHub repositories to bitbucket.
3. **Crypt** – Encrypt and decrypt files.
4. **Cryptocurrency** – Converts Cryptocurrency based on realtime exchange rates of the top 10 cryptos.
5. **Currency** – Currency converter.
6. **Geo** – Provides the details of wan, lan, router, dns, mac, and ip.
7. **Lyrics** – Grab lyrics for a given song quickly from the command line.
8. **Meme** – Command line meme creator.
9. **Movies** – Search and display a movie details.
10. **Newton** – Performs numerical calculations all the way up to symbolic math parsing.
11. **Qrify** – Turns the given string into a qr code.
12. **Short** – URL Shortner
13. **Siteciphers** – Check which ciphers are enabled / disabled for a given https site.
14. **Stocks** – Provides certain Stock details.
15. **Taste** – Recommendation engine that provides three similar items like the supplied item (The items can be books, music, artists, movies, and games etc).
16. **Todo** – Command line todo manager.
17. **Transfer** – Quickly transfer files from the command line.
18. **Weather** – Displays weather details of your place.
19. **Youtube-Viewer** – Watch YouTube from Terminal.
The author might add more utilities and/or features in future, so I recommend you to keep an eye on the project’s website or GitHub page for future updates.
### Bash-Snippets – A Collection Of Useful BASH Scripts For Heavy Commandline Users
#### Installation
You can install these scripts on any OS that supports BASH.
First, clone the GIT repository using command:
```
$ git clone https://github.com/alexanderepstein/Bash-Snippets
```
Go to the cloned directory:
```
$ cd Bash-Snippets/
```
Git checkout to the latest stable release:
```
$ git checkout v1.22.0
```
Finally, install the Bash-Snippets using command:
```
$ sudo ./install.sh
```
This will ask you which scripts to install. Just type **Y** and press ENTER key to install the respective script. If you don’t want to install a particular script, type **N** and hit ENTER.
```
Do you wish to install currency [Y/n]: y
```
To install all scripts, run:
```
$ sudo ./install.sh all
```
To install a specific script, say currency, run:
```
$ sudo ./install.sh currency
```
You can also install it using [**Linuxbrew**][1] package manager.
To installs all tools, run:
```
$ brew install bash-snippets
```
To install specific tools:
```
$ brew install bash-snippets --without-all-tools --with-newton --with-weather
```
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
```
#### Usage
**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.
[![Bash-Snippets][2]][3]
**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
=============================================
```
The above output the **Intel stock** details.
**3\. Weather – Display Weather details**
Let us check the Weather details by running the following command:
```
$ weather
```
**Sample output:**
![][4]
As you see in the above screenshot, it provides the 3 day weather forecast. Without any arguments, it will display the weather details based on your IP address. You can also bring the weather details of a particular city or country like below.
```
$ weather Chennai
```
Also, you can view the moon phase by entering the following command:
```
$ weather moon
```
Sample output would be:
![][5]
**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]
```
Example:
```
$ 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.
The following command displays the details of a movie called “mother”.
```
$ movies mother

| Rated: R
| Genre: Crime, Drama, Mystery
| Director: Bong Joon Ho
| Actors: Hye-ja Kim, Bin Won, Goo Jin, Je-mun Yun

==================================================
```
**6\. Display similar items like the supplied item**
To use this script, you need to get the API key **[here][6]**. No worries, it is completely FREE! Once the you got the API, add the following line to your **~/.bash_profile** : **export TASTE_API_KEY=”yourAPIKeyGoesHere”**``
Now, you can view the similar item like the supplied item as shown below:
```
$ taste -i Red Hot Chilli Peppers
```
