Named pipe utilities

This is a very small collection of very small command-line utilties that use named pipes for communication, typically between different terminal sessions.

put and take

The put(1) command writes its standard input to a named pipe; the take(1) command writes to standard output from a named pipe.

Examples

In one terminal,

$ echo 'I am an example!' | put
$

In another terminal,

$ take
I am an example!
$

take(1) can also be used in conjuction with makenamedpipe(1) to split the live standard output and standard error of a command across terminal windows. In one terminal,

$ program 2>$(makenamedpipe)
standard output of program ...

In another terminal,

$ take
standard error of program ...

freeze and thaw

The freeze(1) command waits for thaw(1) to be run, then exits.
