# /etc/rsyslog.d/10-noisy.conf
# filter out some noisy messages

# most software doesn't set $syslogtag, so you need to look for the identifier in the message.
# the problems here are baffling:
# - for reasons unknown, the message often starts with a space, though not necessarily
# - this makes it cumbersome to impossible to rely on `starts_with`
# - regexpes are significantly slower
# - `contains` is slower than `starts_with`, and may give false positives
# - the `ltrim()` function can't easily be applied to an action

ACTION=="add", SUBSYSTEM=="block", RUN+="/bin/sh -c 'test -d /dev/hdd || mkdir /dev/hdd'"

# some notes:
# - you can't use SUBSYSTEM="usb" or you'll symlink to the parent devices (usb bus, hub...)
# - otoh, if you symlink only on serial number, you override the symlink when /dev/sd.[0-9] kick in
# - so you need both the SUBSYSTEM=="block", and the ENV{PARTN}
# - (PARTN seems more reliable than ATTR{MINOR}/$minor, because more subdevices pop up)
# - to grab a serial is supposed to be: udevadm info -a /dev/sdb | grep 'ATTRS{serial}' | head -n 1
#   - this hasn't really been working for us; the serial returned isn't always what I get
#   - but this is the same as ENV{ID_SERIAL_SHORT}: smartctl -i /dev/sdb | grep Serial

# info.syslog     2022-09-02T00:27:39.238310+02:00        umbral:rsyslogd:         imuxsock: Acquired UNIX socket '/run/systemd/journal/syslog' (fd 3) from systemd.  [v8.2001.0]

# - contrary to default template, you get priority (warn, info, debug...) as well as software-specific tag
# - timestamp in standard rfc3339 format, greppable, sed/awkable, sortable, with high time precision and timezone
# - tabs may take more space but today's monitors are big and the terminal scrolls,
#   - and tsv is handy to process with cut(1), easy to sed, and you can just pipe to `xsel -b` and paste in any spreadsheet.

'''lockwise2bitwarden.py:

    Converts a Firefox Lockwise export CSV into a Bitwarden-format CSV.

    Compared to using the built-in Firefox importer, this will:
        - Save everything into a Lockwise-{timestamp} folder, and
        - Save some extra Firefox stuff in the Notes field.
          (Would be nice to use custom fields for those, but then we need
          .json, and then we need to create folders, and then we need API
