cowsay: Print an ASCII cow with custom eyes saying "hello, world".
$ cowsay -e ${characters} "${hello, world}"
try on your machine
The command "cowsay" is a fun, text-based program in Unix-like operating systems that generates an image of a cow with a speech bubble containing a given message. It uses ASCII art to create the cow image.
In this specific command, "cowsay -e ${characters} "${hello, world}"":
- "cowsay" is the main command that generates the cow image and speech bubble.
- "-e" is an option flag used to specify a particular character set that determines the appearance of the cow's eyes. "${characters}" is a placeholder that should be replaced with the desired character set.
- "${hello, world}" is a placeholder that should be replaced with the message you want the cow to say. In this case, it says "hello, world."
For example, if you wanted to use the "oo" eye character set instead of the default "oo", and have the cow say "hello, world", the command would be: "cowsay -e oo "hello, world""
The output of this command would be an ASCII art image of a cow with a speech bubble containing the message "hello, world", and the eyes of the cow would be represented by the characters specified in the "-e" option.
