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/tsort.

• 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
