# `pipectl` - a simple named pipe management utility

`pipectl` is a tool to create and manage short-lived named pipes that can be

used to e.g. control a longer-lived program using short commands from elsewhere

in the system without needing a complex IPC mechanism such as UNIX domain

sockets.

## Features

- Create a named pipe using `pipectl -o | long-running-program`

- Send something to that program's stdin using `echo "input line" | pipectl -i`

- Create multiple named pipes simultaneously by naming them with `--name` or `-n`

- Create a named pipe at a custom path by using `--path` or `-p`

- Cleans up after itself when the program exits and removes the pipe

- Allows synchronizing writes to the pipe with the `--lock` or `-l` option

## Usage

```

usage: pipectl [options]

options:

  -h, --help    show this help

  -o, --out     create a pipe and print its contents to stdout

  -i, --in      write stdin to an open pipe

  -n, --name N  use a pipe with a custom name instead of the default

  -p, --path P  use a custom path P for the pipe created by pipectl

  -f, --force   force create a pipe even if one already exists

  -l, --lock    use flock(2) to synchronize writes to the pipe

  -v, --verbose print debug messages on stderr

```

## Environment Variables

`pipectl` will use the environment variables `XDG_RUNTIME_PATH` and `TMPDIR` to

discover the preferred directory for the named pipes created by it. If both are

unset, `pipectl` falls back to placing the pipe in `/tmp`.

## Installation

`pipectl` is already packaged in many distros and can be installed via the

package manager:
