Icinga1 Commandline Interface
Project status overview
automated mirrorer for webcomics and image galleries
Create thumbnail index for a set of images
Whitelist remote commands via ssh config
findmnt --raw --noheadings --output options --target SOME_DIRECTORY | grep -qE '(^|,)ro($|,)'
findmntis a handy alternative to
mountwhen writing scripts
- SOME_DIRECTORY does not have to correspond to a mountpoint. If it doesn't, findmnt will traverse its parent directories until it finds the corresponding filesystem / mountpoint.
- a simple
grep rowould also match options like
errors=remount-ro, so we make sure to only match the single
rooption. It must be delimited by commas or the start/end of the option string.
I have a set of maildirs (one for each mailing list / other context) and want to know which of them contains unread mail without firing up my MUA.
Luckily, this is easy to do on the commandline without even looking at mail contents, as there's (mostly?) two kinds of unread mail:
- new and unprocessed mail. These messages are stored in
Maildir/new, so if there's anything in there, it's an unread mail
- new but no longer "Recent" mail. These messages have not been read yet, but
have already been transferred to a MUA using a Read-Write operation, causing
them to be marked as no longer new on the server side. They are stored in
Maildir/curalongside read mail, but do not have the "Seen" (S) flag set.
This is easy to check with zsh globbing:
new/*(N) expands to a non-empty
list if new and unprocessed mail is present, and
cur/*~*,*S*(N) expands to
a non-empty list if old but unread mail is present. Note that it requires
extended_glob zsh option to be set.
TIL: If esptool can successfully communicate with an ESP8266, but the chip seems stone dead otherwise (i.e., no flashed programs work), it may be due to a wrong flash mode.
- The ESP8266 bootloader sends some debug output at 74880 baud after each reset.
- This baud rate is not supported by screen – miniterm.py (provided by python-serial) can handle it just fine, though.
- If it complains about a “
csum err”, you probably flashed the wrong file / at the wrong address / used the wrong flash mode (there are differences e.g. between various NodeMCU / D1 mini shipments!)
esptool -fm doutseems to be a safe (but slow) fallback
- Fix miscalculated delays of prematurely terminating trains
- Lookahead and lookbehind are now interpreted with 1-minute granularity. Note that this also affects the default lookahead.
- Fix floating point-related test failures on some architectures
- Performance improvements
- Distinguish between cancelled/additional arrivals and departures
Travel::Status::DE::IRIS::Result: New accessors
is_cancellednow only returns true if both arrival and departure have been cancelled.
- Remove support for Vorarlberger Verkehrsverbund (VVV) backend (no longer working, apparently superseded by non-EFA software)
- Update EFA URLs for Verkehrsverbund Rhein-Ruhr (VRR2) and Verkehrsverbund Rhein-Neckar (VRN) backends
- Add support for Braunschweiger Verkehrs-GmbH (BSVG)
- Add support for departures in Mainz supplied by the local URA service (MvgMainz)
- ura-m: Show stop-specific messages (if present)
- New module:
Travel::Status::DE::URA->new: add option
