Bash script that waits for changes on files of a directory(watch) and executes a command(do) when a change is detected.
watch-and-do listen for changes in files of a directory. When a change is detected, then it waits a moment for more changes and if there are no more changes, then it executes a command. If the command is running when new changes are detected, then the process, where the command is running, is killed before starting a new process with a new execution of the command.
This bash script was created with the intention to watch changes in a folder of PHP code and then run unit tests with PHPUnit automatically. However it can be used to apply any command instead the PHPUnit command to run tests.
- Install the prerequisites in your local system.
- Clone this repository or download the file watch-and-do inside this repository to your local system.
watch-and-do WATCHDIR COMMAND
- WATCHDIR is the path to the folder to listen for changes in files.
- COMMAND is the command to execute when a change is detected.
$ /path/to/watch-and-do ~/my-project phpunit --group users
In this example, watch-and-do is not installed globally, then the path to the script is used. The first argument, ~/my-project, is the folder to watch for changes. The remaining is the command to execute. Note that --group and users are not arguments to watch-and-do but they are arguments to phpunit. The command could be a path to an executable script. In this example, phpunit is installed globally, so the path to the phpunit script is not required.
