tsort

Perform a topological sort. A common use is to show the dependency order of nodes in a directed acyclic graph. More information: https://www.gnu.org/software/coreutils/manual/html_node/tsort-invocation.html.

• Perform a topological sort consistent with a partial sort per line of input separated by blanks:

tsort path/to/file

• Perform a topological sort consistent on strings:

echo -e "UI Backend\nBackend Database\nDocs UI" | tsort
