Popular `awk` terminal commands

Sort a file by line length

Sorts a text file by line length (including spaces). The `-s` flag indicates that any lines that are the same length are kept in the relative order that they occurred in the input.

Sum all numbers in a file

Uses awk to sum all the numbers in a file. This command is also resilient to big numbers since it internally converts each number to a string.
