Jul 16, 2017 |
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 prices? 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.

Bash-Snippets provides the following 12 useful tools:

  1. currency – Currency converter.
  2. stocks – Provides certain Stock details.
  3. weather – Displays weather details of your place.
  4. crypt – Encrypt and decrypt files.
  5. movies – Search and display a movie details.
  6. taste – Recommendation engine that provides three similar items like the supplied item (The items can be books, music, artists, movies, and games etc).
  7. short – URL Shortner
  8. geo – Provides the details of wan, lan, router, dns, mac, and ip.
  9. cheat – Provides cheat-sheets for various Linux commands .
  10. ytview – Watch YouTube from Terminal.
  11. cloudup – A tool to backup your GitHub repositories to bitbucket.
  12. qrify – Turns the given string into a qr code.
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

Sample output would be:

Cloning into 'Bash-Snippets'...
remote: Counting objects: 1103, done.
remote: Compressing objects: 100% (45/45), done.
remote: Total 1103 (delta 40), reused 55 (delta 23), pack-reused 1029
Receiving objects: 100% (1103/1103), 1.92 MiB | 564.00 KiB/s, done.
Resolving deltas: 100% (722/722), done.

Go to the cloned directory:

cd Bash-Snippets/

Git checkout to the latest stable release:

git checkout v1.11.0

Finally, install the Bash-Snippets using command:

sudo ./

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.

[Apr 05, 2010] Problem with rmlines

As of April 4 this problem was not independently verified, but caution in usage of script is recommended.

I have used rmlines (; but found it to be faulty. Though it worked on my test case, a larger file contained a number of lines that were processed erroneously. I have send a mail to the developer, who wrote back he had no time to look into the (confirmed) problem. On request, I can offer all details, test case, etc. My personal suggestion would be, to remove the link.

Here I used it for administrating a large production server, and it missed out on about 2-3% of the occurrences; to my dismay (and the frustration of my users).

Thanks again, Uwe
