tree: Print files within the tree hierarchy, using a wildcard (glob) pattern, and pruning out directories that don't contain matching files.

$ tree -P '${*-txt}' --prune

The command "tree" is a command-line utility that displays the directory structure of a given file system in a tree-like format.

In this command, the option "-P '${*-txt}'" is used to filter and display only the files that match the specified pattern.

The pattern '${-txt}' is a wildcard expression that matches all files ending with ".txt". Here, '${}' represents any characters (wildcard) before the extension "-txt". Therefore, this pattern will match any file with any name before the ".txt" extension.

The "--prune" option is used to exclude empty directories from the tree view. If a directory does not contain any files or subdirectories, it will be skipped and not displayed in the tree structure.

To summarize, the command "tree -P '${*-txt}' --prune" will generate a tree view of the file system, displaying only the files ending with ".txt" and excluding any empty directories.
