Please note that all the intermediate steps here are, by themselves, invalid, and are just being shown as steps in the process. Only the final step is the correct input. You want that string to all be in a fixed-width font. So to start with, you put .CW in front of it: .CW $ echo "foo bar" But the .CW macro takes a single argument and without any surrounding quotes that argument is going to end with the first space, so you need to enclose the entire argument in double quotes so that it's one argument: .CW "$ echo "foo bar"" Now you have the problem that the interior double quotes that should be part of the argument are going to be interpreted as ending the quoted string that comprises the argument. All of those double quotes inside the quoted argument have to be escaped. The way to do that is to replace each interior double quote with two consecutive double quotes: .CW "$ echo ""foo bar""" This looks like the string ends with three double quotes, but it's better to think of it as one escaped double quote, which is written as "", and then the double quote that ends the argument. This should then produce the output that you want. -- Russ Allbery (ea...@eyrie.org) <https://www.eyrie.org/~eagle/>
