pup:tldr:49a24
This command uses two command-line tools, cat
and pup
, to extract JSON data from an HTML file.
-
cat
is a command used to concatenate and display the contents of files. In this case, it is used to read and display the content of the file referenced by the variable${index-html}
. -
${index-html}
is a variable that holds the name or path of the HTML file. It is assumed that the variable has been previously assigned a valid value. -
The
|
symbol is a pipe and is used to redirect the output of thecat
command to the input of the next command (pup
). -
pup
is a command-line tool used for parsing HTML. It allows you to extract and manipulate data using CSS selectors. In this command, it is used to extract JSON data. -
'${div} json{}'
is a pup command that specifies which elements to extract and their format. In this case, it selects alldiv
elements and then formats the extracted data as JSON.
So, the command reads the content of the HTML file specified by the ${index-html}
variable using cat
, passes it to pup
through the pipe, and extracts all div
elements as JSON data.
