That's great news!

Unfortunately, the "@" in the --date argument is necessary for it to
work correctly when SOURCE_DATE_EPOCH is specified:

  $ date -u "+%F %R:%S %Z" --date=1412583777
  date: invalid date ‘1412583777’
  $ date -u "+%F %R:%S %Z" --date=@1412583777
  2014-10-06 08:22:57 UTC
  $ date -u "+%F %R:%S %Z" --date=
  2017-12-06 00:00:00 UTC

At least, that's how it works on my Debian system...

+No reference from run-parts messages about missing DHCP client.  Turns out Debian 8.10 "Jessie" provides a package named isc-dhcp-client, or offers it as part of their package mirrors lists, but its recommended rather than required when installing the ifupdown package.  Adding this package solved the problem of no action and no messages occurring when attempting to bring up one or another network interface card whose config settings called for DHCP to be applied to those interfaces.  - TMH

+Unfortunately, the "@" in the --date argument is necessary for it to
+work correctly when SOURCE_DATE_EPOCH is specified:
+  $ date -u "+%F %R:%S %Z" --date=1412583777
+  date: invalid date ‘1412583777’

+  $ date -u "+%F %R:%S %Z" --date=
+-12-06 00:00:00 UTC
+At least, that's how it works on my Debian system...

 Simple bash script to back up MYSQL databases to local .sql file, in following figure.  Ted noting that script variables are not consistently capitalized, would be better form to capitalize all or none of them.  Ted also noting that script could read database user passphrase from a file, a file which could be root-only readable and located in a place different from the script, which is likely to be run as a cron job.

+=== [[#top|^]] directory bookmarking script ===
+For ease of navigating long directory paths Ted has written a amending script to the [[bash_start_up_script|Bash start up script]].  The directory bookmarker is open sourced by its author,
+*  https://github.com/tedhavelka/directory-bookmarker
+On a system which has Bash or Gitbash but no default user start up script, a minimal .bashrc file can be created containing something like the following, which happens to be tailored for Gitbash installed under Windows 10:
+<pre>
+#!/usr/bin
+if [ -e $HOME/Desktop/dot-bashrc-amendments.sh ]; then
+    . $HOME/Desktop/dot-bashrc-amendments.sh
+fi
+# --- EOF ---
+</pre>
+This start up file assumes there is a shell script named <code>dot-bashrc-amendments.sh</code> in the user's Desktop directory, under their home directory.  This is a typical Windows path, but not a typical Unix or Linux path.  This path came about during author's early gitbash use, when it was unclear which path gitbash was adopting as the user's home directory.  This uncertainty, it turned out, came from some intermittently available network mapped volumes.  The reader is encouraged to make their own best choice of a stable and sensible path or location for their start up files.
+As of this Monday 2018-11-05 wish list for directory bookmarker script includes:
+<ul>
+  <li> automatic dating of latest update of given bookmark<br />
+  <li> verbose listing of directory bookmarks in given group of bookmarks<br />
+  <li> option for users to give title to each group of bookmarks<br />
+  <li> option for users to further annotate groups of bookmarks<br />

+##
+##  FILE:  .bashrc-amendments, also named dot-bashrc-amendments.sh
+##
+##
+##  LAST TOUCHED:  2017-12-14 THU
+##
+##
+##  DESCRIPTION:  short script to amend Debian and Ubuntu and or
+##    Bourne shell run-time config file, normally named '.bashrc'.
+##    Adds directory book-marking for up to thirty directories -- or
+##    file system paths -- making these accessible by means of
+##    three- and four- character aliases of the form 'gdnn' where
+##    nn is an integer in the range 1 to 30.
+##
+##
+##  HOW TO USE THIS SCRIPT:
+##
+##    To enjoy directory bookmark aliases in this file, in a bash
+##    command line environment, the user may source this file by
+##    hand,
+##
+##    $ . dot-bashrc-amendments.sh
+##
+##    or alternately for convenience a given user may amend their
+##    .login or .bashrc start-up script to include a line which
+##    does the same sourcing of this file.
+##
+##
+##
+## - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
+##
+##  NOTES ON IMPLEMENTATION:
+##
+##   (1) When this script is called with no arguments, it reads a run-
+##     time config file to determine which group of file-stored,
+##     bookmarked paths to read into shell variables and to make readily
+##     accessible via path navigation aliases.  If the run-time config
+##     is not found the shell creates it and populates it with its
+##     identifier '1' for the first group among 1..9 supported groups
+##     of path (also referred to as directory) bookmarks.
+##
+##   (2) When this script is called with a first argument in the range
+##     1..9, a single character number representation, the script
+##     writes this number to its run-time config file, and uses this
+##     number to choose among groups of saved paths written to the
+##     given user's dot-bashrc-amendments stored path files.  If not
+##     called with a valid bookmarks group id, this script falls back
+##     to doing the tasks in (1)
+##
+##
+##
+##
+##  TO DO:
+##
+##    [ ]  add to this script function which detects and shows
+##         the script's own aliases, and another function(s) to
+##         allow user to change aliases, e.g. in event that alias
+##         conflicts with a locally installed command,
+##
+##    [ ]  add to this script the ability to open arbitrary text
+##         file containing bookmarked paths, and to show it without
+##         replacing present bookmarks,
+##
+##    [ ]  add to this script a function to show bookmarks it
+##         holds and status of whether each given bookmark exists
+##         as a valid path on the local file system,
+##
+##    [ ]  2017-12-02 - add parameters sanity check to routine 'read_bookmarks_file',
+##
+##    [ ]  2017-12-02 - add settings file to store latest selected group of bookmarks,
+##
+##
+##
+##
+##
+##  TO CONFIRM:
+##
+##    [ ]  2017-12-02 - make sure that variable 'index' is visible in
+##         the scope of the script which sets the alias 'sp' which
+##         saves bookmarked paths,

+=== [[#top|^]] shell arrays and array implementation ===
+Classic Unix/*nix shell command interpreters are not designed to provide full or detailed mathematical operations support.  Variables tend to be weakly typed and treated as strings, but Bourne Again SHell or bash has some basic math facilities.  This in turn lends support to some limited, kind of clunky array syntax.  But this array facility in one or more versions of Unix based shell can be better than no array support.  Some references:
+*  https://www.geeksforgeeks.org/array-basics-shell-scripting-set-1/
+*  https://tldp.org/
+  *  https://tldp.org/LDP/abs/html/arrays.html
+Also may be worth looking at example 11-14, second shell script which omits 'do' and 'done' keywords in shell FOR-loop construct:
+  *  https://tldp.org/LDP/abs/html/loops1.html
+. . . there may be syntax here which allows for more sane, flexible array element assignments.

+Beyond the biodiverse forests on the outer edges of Madeira Island, the land rises, reminding hikers that this Portuguese island is the tip of a shield volcano. Trails allow passage up into these higher elevations, including paths created from the island’s old (and still functioning) aqueduct system. Some of the decommissioned channels, called levadas, have been repurposed as hiking trails.
