Merge 295fe153ad into 60b6aa40ad

Hello, I've added a small blockquote below the description to indicate that this method of accessing an indefinite number of function arguments has been superseded by the use of the spread operator via rest parameters for ES6+ compatibility.

+# Open Current Tab In New Window With Vimium
+
+Sometime I have a busy Chrome window going with a bunch of tabs open for
+various lines of work as well as a number of tabs that I've neglected to close.
+I then open a new tab, find something useful, and realize I'm at a "branching
+point". I'm about to start in on a specific chunk of work that will probably
+involve opening several more tabs and switch back and forth between some
+dashboards. I want to start all of this from a fresh slate -- or at least from
+a fresh Chrome window.
+
+With [Vimium](https://github.com/philc/vimium), I can hit `W` (`Shift-w`) to
+have the current tab move from the current window to a new window. The original
+window, minus that one tab, will be left as is so that I can go back to it as
+needed.

+# Have Script ShellCheck Itself When Executing
+
+The [ShellCheck](https://www.shellcheck.net/) utility can be run against bash
+scripts to check if there are any warnings or errors we should fix. It works
+great as long as we remember to run it.
+
+I wondered if I could make it easier on myself by not having to remember to run
+it. What if my bash script were to `shellcheck` itself?
+
+Here is an example script where at the beginning it looks for and runs the
+`shellcheck` utility against `$0` (the path of the script). This is kind of
+meta. As the script is executing, it has an external program run against the
+entire contents of itself. If there are any `shellcheck` issues, they get
+displayed and the program exits early.
+
+```bash
+#!/bin/bash
+
+# Exit immediately if any command fails
+set -e
+
+# Self-validation using ShellCheck
+if command -v shellcheck &> /dev/null; then
+    echo "Validating script with ShellCheck..."
+
+    # $0 refers to the script itself
+    if ! shellcheck "$0"; then
+        echo "ShellCheck found issues in the script. Exiting."
+        exit 1
+    fi
+    echo "Script validation passed."
+else
+    echo "Warning: ShellCheck not found. Skipping validation."
+fi
+
+echo "Script execution continuing..."
+
+# shellcheck warning here
+read -p "Continue with current operation? (yes/no): " CONTINUE_WITH_EXISTING
+if [[ ! "$CONTINUE_WITH_EXISTING" =~ ^[Yy][Ee][Ss]$ ]]; then
+    echo "Operation cancelled."
+    exit 1
+fi
+```
+
+This last bit of the script with the `read` command will trigger a warning from
+`shellcheck`.
+
+```bash
+$ ./check.sh
+Validating script with ShellCheck...
+
+In ./check.sh line 23:
+read -p "Continue with current operation? (yes/no): " CONTINUE_WITH_EXISTING
+^--^ SC2162 (info): read without -r will mangle backslashes.
+
+For more information:
+  https://www.shellcheck.net/wiki/SC2162 -- read without -r will mangle backs...
+ShellCheck found issues in the script. Exiting.
