The diffoscope command is a tool used to compare and analyze differences between two directories or files.
In the given command, "--exclude ${pattern}" is an optional argument that allows you to exclude certain files or directories from the comparison. ${pattern} represents the pattern or name of the files/directories you want to exclude. It can be a regular expression pattern or just a simple name.
"${path-to-directory1}" and "${path-to-directory2}" are the paths to the directories you want to compare. These paths should be replaced with the specific paths to the directory you want to compare.
By executing this command, you will be running the diffoscope tool and comparing the contents of the two directories, while excluding any files or directories that match the given pattern.
