Bash-Snippets - A Collection Of Useful BASH Scripts For Heavy Commandline Users

An active Internet connection is required to use most of these Bash scripts. The usage is fairly simple. Let us see how to use some of them. I assume you have installed all scripts.

1. Currency - Currency Converter

This Bash 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.

4. Crypt - Encrypt and Decrypt files

This script is a wrapper for openssl that allows you to encrypt and decrypt files quickly and easily.

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:

5. Movies - Find Movie details

Hi, thank you for the useful scripts, I’m currently using the ytview one. Just a little suggestion from me, it would be better if you could show the channel name & duration of the video too when searching for one, so the search result would look like this: [ChannelName] – [VideoTitle] – [VideoDuration]

I’m afraid this feature is not available in ytview script. Please send a feature request to the developer in GItHub. https://github.com/alexanderepstein/Bash-Snippets.

These are awesome scripts! Thanks! I have no problem running them anywhere on my Ubuntu machine, (I wanna say I didn’t even have to edit my $PATH, just started typing the commands and they worked), but when I downloaded them onto my mac via my bash terminal, for example I can only get the commands to run if I go into that script’s directory in this case geo and use the ./geo command.

Hi, great scripts, thanks.
Question though – how do you search for stocks or their symbols?
It’s easy for one word like Tesla or Intel, but how to search for example: Berkshire Hathaway?

That’s is a very good collection of little programmes!
However, I think the approach for getting bank currency rates is awkward: you must answer 3 questions and gets a bloated result.
I suggest a more UNIXy approach to get bank currency rates with the same excellent API these guys are using…

So I implemented a more ( what I expect to be) straightforward syntax with this Bash script. You can download it from the link below and test it. Run with “-h” to get a help page and get started. But syntax would be “erates.sh 1 USD JPY” to get the equivalent of one-US-Dollar in Japanese Yen.

Nice! Put it on GitHub and make it available for everyone.

I was looking in the source code and there is a nice function there..
It is easier if I just paste the comment from it (line 106):

## This function queries google to determine the stock ticker for a certain company
## this allows the usage of stocks to be extended where now you can enter stocks appple
## and it will determine the stock symbol for apple is AAPL and move on from there

So what you ask for should be working by default (even though this specific bash script does not work in my computer at all!)
