Tsort (Unix)
From Wikipedia, the free encyclopedia
- The correct title of this article is tsort. The initial letter is shown capitalized due to technical restrictions.
tsort is a command line utility initially written for use with the Unix operating system. It performs a topological sort on the standard input.
Common use:
$ tsort <option> processname ...
Let's make an example; if myfile is
a s b a a a
the output of
tsort myfile
is
b a s
According to its info page, this command was initially written for the linking of the programs in the first versions of Unix, where a file were processed in order; but since the usage of ar or ranlib, which generate symbols table before linking, this utility has lost its importance.
