1. PV command
You may have seen the mock captions in the movie, they seem to have been knocked out in real time. Wouldn't it be nice if I could achieve this effect in the terminal?
This can be done. We can install the ' PV ' command on Linux systems via ' apt ' or ' yum ' tool. The installation commands are as follows.
The code is as follows:
# Yum Install PV
[on RedHat based Systems]
The code is as follows:
# sudo apt-get install PV
[on Debian based Systems]
After the ' PV ' command was successfully installed, we tried to run the following Single-line command to view the effect of live text output at the terminal.
The code is as follows:
$ echo "Tecmint[dot]com is a community of Linux nerds and Geeks" | PV-QL 10
Note: the ' q ' option indicates ' quiet ', no other output information, the ' L ' option indicates the maximum number of bytes converted per second. Adjust the value of a number (which must be an integer) to display the text effect in a different direction.
2. Toilet command
Using a single-line script command ' toilet ' to display a text with a border added to the terminal what about it? Again, you have to make sure that ' toilet ' is installed on your computer. If not, please use apt or yum installation. (Translator note: ' Toilet ' is not in Fedora's official warehouse, you can download the source code from GitHub to install)
The code is as follows:
$ while true; Do echo $ (date | Toilet-f term-f border–tecmint) "; Sleep 1; Done
Note: The above script needs to be paused using the Ctrl+z key.
3. Rig command
This command generates a random identity message and address at a time. To run this command, you need to install ' rig ' with apt or yum. (Translator: ' Rig ' is not in Fedora's official warehouse, I only found the Ubuntu Deb on Rpmseek and can use it to install.)
The code is as follows:
# rig
4. Aview command
What do you think of displaying pictures in the terminal in ASCII format? We must install the package ' Aview ' with apt or yum. (Translator Note: ' Avieww ' is not in Fedora's official warehouse and can be installed by downloading source code from Aview's Project home page.) There is a picture named ' Elephant.jpg ' in the current working directory, and I want to view it in ASCII mode on the terminal.
The code is as follows:
$ Asciiview Elephant.jpg-driver Curses
5. Xeyes command
In the last article, we introduced the ' Oneko ' command, which shows a mouse that follows the mouse pointer movement. ' Xeyes ' is a similar graphics program, and when you run it, you can see the little monster's two eyeballs following your mouse movement.
The code is as follows:
$ xeyes
6. Cowsay command
Do you remember the last time we introduced this order? It can display a predetermined text and a character consisting of a cow. What if you want to use other animals instead of cows? View list of available animals:
The code is as follows:
$ cowsay-l
How to use ASCII to depict snake-like swallowing?
The code is as follows:
$ cowsay-f elephant-in-snake Tecmint is best
What happens to a goat?
The code is as follows:
$ cowsay-f GNU Tecmint is best
