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 make rapid feedback and
automated testing natural and completely ordinary.
Source Installation - BSD, Mac OS, and Linux
--------------------------------------------
./configure
make test
make install
To see available build options run `./configure -h`
Docker and Windows Subsystem for Linux
--------------------------------------
Incomplete inotify support on WSL and Docker for Mac can cause `entr`
to respond inconsistently. Since version 4.4, `entr` includes a workaround:
Set the environment variable `ENTR_INOTIFY_WORKAROUND`.
`entr` will confirm the workaround is enabled:
```
entr: broken inotify workaround enabled
```
Man Page Examples
-----------------
Rebuild a project if source files change, limiting output to the first 20 lines:
$ find src/ | entr sh -c 'make | head -n 20'
Launch and auto-reload a node.js server:
$ find . -name '*.js' | entr -r node app.js
Clear the screen and run a query after the SQL script is updated:
$ echo my.sql | entr -p psql -f /_
Rebuild project if a source file is modified or added to the src/ directory:
$ while sleep 0.1; do find src -name '*.rb' | entr -d make; done
Self-terminate after a file is updated
$ find . -type f | entr -p 'kill $PPID'
