pygmentize:tldr:d2aee

The given command pygmentize is a syntax highlighting tool used in programming and markup languages. Let's break down the different parts of the command:

1. pygmentize: It is the executable command for pygmentize, the syntax highlighting tool.

2. -f html: It specifies the output format. In this case, the output will be in HTML format.

3. -O "full,linenos=True": The -O option is used to pass options to pygmentize. In this case, it sets the options full and linenos to True. full means that the entire file is highlighted, and linenos adds line numbers to the highlighted code.

4. -o ${output_file-html}: It specifies the output file name. In this command, the output file name is defined using a variable called output_file. If that variable is not set, a default value html is used as the output file name.

5. ${input_file}: It specifies the input file name. It is expected that there is a variable named input_file that contains the actual input file name. The command will read this file and apply syntax highlighting to it.

To summarize, this command uses pygmentize to highlight the syntax of a given input file (specified by ${input_file}), generates the highlighted code in HTML format, adds line numbers, and saves the output to a file (specified by ${output_file-html}).
