texliveonfly:tldr:3b14e

This command is most likely used in a Unix-like operating system (e.g., Linux) to run a TeX document using the texliveonfly script.

Here is the breakdown of the command:

texliveonfly: This is the name of the script being executed. It is a utility provided by the TeX Live distribution to automatically download and install any missing packages required by a TeX document.

--texlive_bin=${path-to-texlive_bin}: This is an option passed to the script specifying the location of the texlive_bin directory. The ${path-to-texlive_bin} placeholder should be replaced with the actual path to the directory containing the TeX Live binaries.

${source-tex}: This is another placeholder that should be replaced with the actual path to the TeX source file (*.tex) you want to compile.

When this command is executed with the appropriate values for ${path-to-texlive_bin} and ${source-tex}, the texliveonfly script will be invoked to compile the TeX document. It will check for any missing packages using the specified texlive_bin directory and automatically download and install them if needed, ensuring that the document can be successfully compiled without any missing dependencies.
