Event Notify Test Runner
========================
A utility for running arbitrary commands when files change. Uses kqueue(2) or
inotify(7) to avoid polling. `entr` was written to facilitate rapid feedback
on the command line.
Source Installation - BSD, Mac OS, and Linux
--------------------------------------------
./configure
make test
make install
To see available build options run `./configure -h`
Docker and WSL
--------------
Incomplete inotify support on _Windows Subsystem for Linux_ and _Docker for Mac_
may cause `entr` to respond incorrectly. Setting the environment variable
`ENTR_INOTIFY_WORKAROUND` enables `entr` to operate in these environments.
Linux Features
--------------
Symlinks can be monitored for changes by setting the environment variable
`ENTR_INOTIFY_SYMLINK`.
Man Page Examples
-----------------
Rebuild a project if source files change, limiting output to the first 20 lines:
$ find src/ | entr -s 'make | head -n 20'
Launch and auto-reload a node.js server:
$ ls *.js | entr -r node app.js
Clear the screen and run a query after the SQL script is updated:
$ echo my.sql | entr -cp psql -f /_
Rebuild project if a source file is modified or added to the src/ directory:
$ while sleep 0.1; do ls src/*.rb | entr -d make; done
Auto-reload a web server, or terminate if the server exits
$ ls * | entr -rz ./httpd
