+fatrace - report system wide file access events
+
+## monitor filesystem access by process name
+
+figure out why your hard drives are waking up at seemingly random times.
+
+**just monitor the current mount point**
+
+to only monitor filesystem access in the mounted path `/mnt`, change into that directory and use the `-c` flag. `-t` adds a timestamp and `-o` writes everything out to a file
+
+```shell
+cd /mnt
+fatrace -c -t -o /tmp/fatrace.log
+```
