Beepmein
A reminder/alarm script using ‘at’ as back.
beepmein now + 3 minutes
^
'at' time format
beepmein 22:10
^
also 'at' time format
beepmein 3
^
in 3 minutes (beepmein shortcut)
beepmein --alarm 8:00
^
Will play audio sample,
that you defined by setting alarmSample.
Must be first parameter.
beepmein --test # test beep and notification
# More testing
beepmein --reaction reminder_text
beepmein --reaction --alarm alarm_text
killall beepmein # kill all running playback/beeping
# Notes:
at -l # will list pending jobs (or atq)
at -r <num> # will remove job <num> (or atrm)
Note: ‘at’ doesn’t use seconds, max precision seems to be minutes.
Some debate.
With Debian buster ‘at’ jobs may be found in /var/spool/cron/atjobs.
pipeBeepmein
Pipe-menu of some sort intended for jgmenu, using cvs format.

Naive script to convert hex colors as seen in .Xresources to Lxterminal friendly format.
https://raw.githubusercontent.com/brontosaurusrex/bucentaur/master/.experiments/bin/urxlx
Usage:
urxlx ~/.Xresources | xclip
Converts this
! special
*.foreground: #f8f8f2
*.background: #272822
*.cursorColor: #f8f8f2
! black
*.color0: #272822
*.color8: #75715e
! red
*.color1: #f92672
*.color9: #f92672
...
to this
fgcolor=rgb(248,248,242)
bgcolor=rgb(39,40,34)
palette_color_0=rgb(39,40,34)
palette_color_8=rgb(117,113,94)
palette_color_1=rgb(249,38,114)
palette_color_9=rgb(249,38,114)
...
then paste the results to strategic location in ~/.config/lxterminal/lxterminal.conf and win.

Note: Do backup ~/.Xresources first.
