In our past following articles, we’ve shown some useful articles on some funny commands of Linux, which shows that Linux is not as complex as it seems and can be fun if we know how to use it. Linux command line can perform any complex task very easily and with perfection and can be interesting and joyful.
The former Post comprises of 20 funny Linux Commands/Script (and subcommands) which was highly appreciated by our readers. The other post, though not that much popular as former comprises of Commands/ Scripts and Tweaks which lets you play with text files, words, and strings.
This post aims at bringing some new fun commands and one-liner scripts which is going to rejoice you.
1. pv Command
You might have seen simulating text in movies. It appears as, it is being typed in real-time. Won’t it be nice, if you can have such an effect in terminal?
This can be achieved, by installing ‘pv‘ command in your Linux system by using ‘apt‘ or ‘yum‘ tool. Let’s install ‘pv‘ command as shown.
# yum install pv [On RedHat based Systems] # sudo apt-get install pv [On Debian based Systems]
Once, ‘pv‘ command installed successfully on your system, let’s try to run the following one-liner command to see the real-time text effect on the screen.
$ echo "Tecmint[dot]com is a community of Linux Nerds and Geeks" | pv -qL 10
Note: The ‘q‘ option means ‘quiet’, no output information and option ‘L‘ means the Limit of Transfer of bytes per second. The number value can be adjusted in either direction (must be an integer) to get the desired simulation of text.
2. toilet Command
How about printing text with border in a terminal, using a one-liner script command ‘toilet‘. Again, you must have ‘toilet‘ command installed on your system, if not use apt or yum to install it.
$ while true; do echo “$(date | toilet -f term -F border –Tecmint)”; sleep 1; done
Note: The above script needs to be suspended using ctrl+z key.
3. rig Command
This command generates a random identity and address, every time. To run, this command you need to install ‘rig‘ using apt or yum.
4. aview Command
How about viewing an image in ASCII format on the terminal? We must have a package ‘aview‘ installed, just apt or yum it. I’ve got an image named ‘elephant.jpg‘ in my current working directory and I want to view it on the terminal as ASCII format.
$ asciiview elephant.jpg -driver curses
5. xeyes Command
In the last article, we introduced a command ‘oneko‘ which attaches jerry with a mouse pointer and keeps on chasing it. A similar program ‘xeyes‘ is a graphical program and as soon as you fire the command you will see two monster eyes chasing your movement.
6. cowsay Command
Do you remember last time we introduced command, which is useful in the output of the desired text with an animated character cow. What if you want other animals in place of cow? Check a list of available animals.
$ cowsay -l
How about Elephant inside ASCII Snake?
$ cowsay -f elephant-in-snake Tecmint is Best
How about Elephant inside ASCII goat?
$ cowsay -f gnu Tecmint is Best
That’s all for now. I’ll be here again with another interesting article. Till then stay update and connected to Tecmint. Don’t forget to provide us with your valuable feedback in the comments below.
