duc: Index the /usr directory, writing to the default database location ~/.duc.db.
$ duc index ${-usr}
try on your machine
The command "duc index ${-usr}" is using the "duc" command-line tool to index user directories.
Here's a breakdown of the command:
- "duc": It is the name of the command-line tool.
- "index": It is the subcommand of the "duc" tool used to create an index of file sizes in directories.
- "${-usr}": It is a variable being used within the command, but its value is not provided in the given command. In shell scripting, the "$" symbol is used to denote a variable, and here "${-usr}" is referring to a variable named "-usr". The value of this variable would typically be provided elsewhere in the script or command invocation.
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.
