duc: Run the ncurses console interface to explore the file system.
$ duc ui ${-usr}
try on your machine
This command seems to be written in a shell scripting language, like Bash.
The command starts with "duc ui" which suggests that it is invoking the "ui" subcommand of a program called "duc".
"${-usr}" is a variable surrounded by curly braces. The hyphen before "usr" implies that it is a negative flag, indicating the absence of the "usr" flag. The use of the curly braces is likely adding context to the variable name.
Without further information about the "duc" program and its available options, it is difficult to provide a definitive explanation. However, based on common patterns in command-line interfaces, it is possible that the command is executing the "ui" subcommand of "duc" with the "usr" flag disabled or removed.
This explanation was created by an AI. In most cases those are correct. But please always be careful and
never run a command you are not sure if it is safe.
