Linux command line can perform any complex task very easily and with perfection and can be interesting and joyful.

Funny Linux Commands

The former Post comprises 20 funny Linux Commands/Script (and subcommands), which our readers highly appreciate. The other post, though not that popular as the former comprises 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 with 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 the ‘pv‘ command in your Linux system by using the ‘apt‘ or ‘yum‘ tool. Let’s install the ‘pv‘ command as shown.

$ sudo apt install pv  [On Debian/Ubuntu & Mint]
$ sudo yum install pv  [On CentOS/RHEL 7]
$ sudo dnf install pv  [On CentOS/RHEL 8 & Fedora]
$ sudo pacman -S pv    [On Arch Linux]
$ sudo pkg_add -v pv   [On FreeBSD]

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 
install pv command

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.

$ sudo yum install toilet  [On CentOS/RHEL 7]
$ sudo dnf install toilet  [On CentOS/RHEL 8 & Fedora]
$ sudo pacman -S toilet    [On Arch Linux]
$ sudo pkg_add -v toilet   [On FreeBSD]

Once installed, run:

$ while true; do echo “$(date | toilet -f term -F border –Tecmint)”; sleep 1; done
install toilet in linux

Note: The above script needs to be suspended using the 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.

$ sudo pacman -S rig    [On Arch Linux]
$ sudo pkg_add -v rig   [On FreeBSD]

$ sudo dnf install xeyes  [On CentOS/RHEL 8 & Fedora]
