 This command attempts to parse every URL for every package in Spack
 and prints a summary of how many of them are being correctly parsed.
 It also prints a histogram showing which regular expressions are being
 matched and how frequently:
 
-.. command-output:: spack url test
+.. command-output:: spack url summary
 
 This command is essential for anyone adding or changing the regular
 expressions that parse names and versions. By running this command
