d1216a4253 Add an example of trap command (#1826) 
* Begin writing document for PCRE

Started writing learnxinyminutes document for PCRE to cover general purpose regular expressions. 
Added introduction and a couple of details.

The old example was incorrect. It's replaced with a simple one.

* Add first example

* Added more example and a table for proper formatting

* Add few more examples

* Formatting

* Improve example

* Edit description of character classes

* Add a way to test regex

Add https://regex101.com/ web application to test the regex provided in example.

* Add example of trap command 

trap is a very important command to intercept a fatal signal, perform cleanup, and then exit gracefully. It needs an entry in this document.

Here a simple and most common example of using trap command i.e. cleanup upon receiving signal is added.

* Revert "Add example of trap command"

8b7a2fff9a Don't use ALL_CAPS variable names. 
ALL_CAPS variable names are traditionally "reserved" for use by the
shell/system.

(People often try to use PATH for things locally and then wonder why their
commands all stop working for example.

248284c91b [bash] Replace seq with {1..3}, explain backticks 
`seq` is not standard, it's not available in MINGW and others.
Using backticks is not the recommended way - e.g. they can't be nested.
