+# Execution-counter
+This program uses `inotify` ([man page](https://man7.org/linux/man-pages/man7/inotify.7.html)) to monitor file accesses for each file in $PATH. A potential use-case is to find which files are not needed in a docker-image.
+
+
+## Build
+```
+gcc exec_tracker.c -o exec_tracker
+```
+
+
+## Usage
+```sh
+# Track number of times executables in PATH are accessed
+./exec_tracker
+
+# Track number of times regular files in <directory> is accessed
+./exec_tracker <directory>
+```
+
+## Acknowledgments
+The code borrows heavily from the `inotify` manual page in the Linux Programmer's Manual.
