run-when

Monitor filesystem for changes and run a specific executable some time after the changes are announced.

Usage

sh run-when --help

``` run-when 1.0.0 Aalekh Patel Run a (debounced) command upon changes to the filesystem.

USAGE: run-when [OPTIONS] --file --command-file

OPTIONS: -c, --command-file An executable to run once a change is detected

-f, --file <FILE>
        The file/directory to watch. If a directory is specified, will watch all files in it
        (but not recursively, unless -r is also specified)

-h, --help
        Print help information

-r, --recursive
        Whether to watch a directory recursively

-t, --debounce-period <DEBOUNCE_PERIOD>
        The debounce period (i.e. wait for a duration of X before running the specified
        executable) [default: 600ms]

-V, --version
        Print version information

```

Examples

• Watch the src directory for changes and once every 600ms run the build script stored in build.sh.

Suppose the contents of build.sh are:

```sh

!/usr/bin/sh

cargo build --release ```

Then we can run the following to start a watcher on the src directory and all children files recursively. sh run-when --file src --recursive --command-file ./build.sh
