Show HN: Mustardwatch: Detect what files a program uses, rerun when they change

Usage: mustardwatch [OPTION...] COMMAND [ARG...] Run a command, tracing it to detect files it uses (or might use), and watch those files for changes. When a file changes, rerun the command. File events generated while the command is running are ignored. Files in common global directories (/bin, /dev, /etc, /lib, /proc, /sys, /tmp, /usr) are skipped by default. Files used by subprocesses are also tracked (but note that all subprocesses are killed when the main process exits). Options: -c, --clear clear screen before running program -d, --directories watch directories as well as regular files -g, --global do not skip files in common global directories -o, --out=FILE rather than respawning the process when files change, write out a list of watched files to FILE, then exit -v, --verbose show verbose output (watched files and events) (use multiple times for more verbose output) --help print this message
