What is tsort info?

Tsort is a command-line utility in Unix-like operating systems that is used to perform topological sorting on directed graphs. It takes a list of items as input, along with a list of pairs representing the dependencies between the items, and outputs a sorted list of items such that for any pair of items A and B, if A depends on B, then B appears before A in the sorted list.

Tsort is commonly used in software build systems and package managers to determine the order in which dependencies should be built or installed. It is a simple but powerful tool for managing complex dependencies and ensuring that tasks are executed in the correct order.

The tsort command can be run from the command line with the syntax:

tsort [inputfile]

Where [inputfile] is a file containing the list of items and their dependencies. The output of tsort is a sorted list of items, which can be redirected to a file or used as input to another command.

Overall, tsort is a useful tool for managing dependencies and ensuring that tasks are executed in the correct order in complex systems.
