pup: Transform a raw HTML file into a cleaned, indented, and colored format.

$ cat ${index-html} | pup --color

try on your machine

This command is a combination of two separate commands piped together using the "|" symbol.

cat ${index-html}: The cat command is used to read and display the contents of a file. In this case, ${index-html} is a variable that represents the name of a file. The exact value of this variable is not mentioned in the command. The contents of the file will be displayed by the cat command.
pup --color: The pup command is a command-line tool used for parsing HTML. It extracts data from the HTML structure using CSS selectors. In this case, --color is an option provided to the pup command to display the output with color highlighting.

So, when both commands are combined using the pipe symbol, the output of the cat command (file contents) will be passed as input to the pup command, which will parse the HTML and display the output with color highlighting.
