d69a3c8e3a Very useful when you need to test for certain permissions. I imagine 
this would be most useful when dealing with more advanced permission
schemes.

c12d8e2df2 Show counting lines awk reads from STDIN 
This is useful, but not if this is _all_ you're after; in those
cases, you're better off just using `free | wc -l` or similar.

However, there may be times you need to count the number of lines in
order to achieve _other_ things programmed in awk, which would then be
crucial!

For example, you may wish to output text informing the user of how many
log entries were discovered in one or more files given to awk.

ff4af91485 Access environment variables from within awk. 
ENVIRON is a special associative array variable, and LS_COLORS is an
index therein. If you want to see the available variables you could
use, you could execute the trusty `env` command.

fec416c763 Show using awk without data via STDIN 
This is useful for those times you want to just do something in awk, -
on-the-fly, without having to rely on its standard input (STDIN).

It's especially handy when you want to perform floating-point
arithmetic, if you're not a shell like ZSH which does support it.

Fix Merge two dicts 
The square brackets are wrong and will generates a `SyntaxError`, the correct way is to use curly brackets. I have tested this before making the update.
