Submagic

A tiny utility that redirects stdin into a temporary file and then prints the full path to that file.

Why do I need this?

It helps you in situations where you’d like to feed the output of a program foo into another program bar, but bar only accepts a file name as an argument and refuses to work with standard input or Bash’s process substitution.

In other words, submagic allows you to run a shell command line like:

foo | submagic | xargs bar

if foo emits standard output but bar only accepts files.

This is the solution for the question Creating a temporary file from standard input on Unix Stack Exchange.

For practical usage examples, see USAGE.md.
