duc:tldr:f5117
The command "duc ls -Fg -R ${-usr-local}" has the following components:
-
"duc" is the name of the command being executed. It is likely referring to the "Disk Usage" tool, which is used to analyze and display disk usage statistics.
-
"ls" is an argument or option provided to the "duc" command. It instructs the command to list the specified directories or files.
-
"-Fg" are additional arguments or options provided to the "duc ls" command:
- "-F" option displays file types using appended characters, such as a slash '/' for directories.
- "-g" option displays the output in a human-readable format, using appropriate units (e.g., kilobytes, megabytes, gigabytes).
-
"-R" is an argument or option provided to the "duc ls" command. It stands for "recursive" and tells the command to list directories and files recursively, i.e., including all subdirectories.
-
"${-usr-local}" seems to be a shell variable or parameter being used in the command. The exact meaning and value of this variable would depend on the context in which the command is being run.
