Jul 16, 2017 | www.ostechnix.com

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 https://github.com/alexanderepstein/Bash-Snippets

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 ./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.

[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 (http://comp.eonworks.com/scripts/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

    • Here are scripts for the Bourne Again Shell (bash). They are mostly for tutorial purposes, as some do not really do anything useful, other than display information, or do simple calculations. Some are more complicated and are useful in the concept of what they were made to do. They are all free to use if you may desire so. (Luke Th. Bullock 1997)

  • These are some scripts, configuration files and man pages from my Unix/X Window System home environment. They were developed and collected to allow me to maintain an enhanced, consistent home environment across many varieties of Unix and many separate home directories. As such, they generally favor portability over efficiency and restrict themselves to ubiquitous Unix tools when possible, but take advantage of better tools when available. As a systems administrator in a heterogenous environment, I've found them to be useful.

    Feel free to browse and borrow from these files as you wish. I'm afraid there's often little or no documentation or comments, so you may be on your own to figure out what some of them are good for. Most of my scripts (ie, except those in the "Other Authors" section) will only print a usage message if run with a -h flag. Most of the scripts will port "as is" to most versions of Unix and have any configuration options specified at the top of the script file.
