textutil:tldr:075af

The command you provided is:

textutil -convert ${rtf} -font ${Times} -fontsize ${10} ${path-to-foo-txt}

This command is using the textutil utility to convert a text file foo.txt to an RTF (Rich Text Format) file with specific font and font size.

Here is an explanation of each part of the command:

• textutil: It is a command-line tool available on macOS that can manipulate various types of text documents.
• -convert ${rtf}: This option specifies the conversion format for the input file. In this case, the rtf variable is used, which should contain the desired output format.
• -font ${Times}: This option sets the font of the output RTF file. The Times variable is used here to specify the font name.
• -fontsize ${10}: This option sets the font size of the output RTF file. The 10 variable is used here to specify the font size.
• ${path-to-foo-txt}: This is the path to the input text file (foo.txt). The command will convert this file to an RTF file with the specified font and font size.

Note: The ${} syntax suggests that the values for rtf, Times, and 10 may be variables that should be replaced with their actual values when running the command.
