listtrs

Listtrs is a non-interactive, command-line utility used for listing contents of a tree-like filesystem structure. It is designed to be a minimal and straightforward tool, making it easy to use and customize. Listtrs is typically invoked from the command line, where it takes a list of filenames as input, listing them in a directory tree format.

Listtrs' primary functionality can be described as a hybrid between a tree listing tool and a directory walker. It recursively traverses the directory structure, printing the file hierarchy in a precise and consistent format. This feature makes listtrs particularly useful for developers and system administrators who require a detailed representation of a project's directory structure.

In an effort to maintain parsimony, the listtrs command-line interface is deliberately restricted. The tool does not accept switches or directives to customize its behavior, with the exception of whether the listrsexec flag is set. When enabled, this flag causes listtrs to execute external commands attached to nodes in the output tree. This allows for users to perform customized actions during the processing of the directory structure, further increasing the utility of the tool.

It is worth noting that listtrs was initially designed with compatibility and minimalism in mind, adhering to traditional Unix-like philosophy. This approach has led to widespread adoption across a variety of Linux distributions, and has piqued the interest of open-source enthusiasts and system engineers alike. As a direct result of these values, listtrs has seen regular contributions and adaptation to suit diverse needs.
