+#### My solutions to the [advent of code 2020](https://adventofcode.com/2020)
+
+My solutions to the 2 daily exercises in both C and Bash (also Cobol for day 1, I may try some other languages).
+
+#### My own rules:
+ - **C** : Only *standard* libraries (for example, no external sort).
+ - **bash**: Pure bash only: No external commands allowed (grep, sed, etc...).
+
+#### Done:
+ -  Day  1:     Bash, C, and Cobol
+ -  Days 2-18:  Bash and C
+ -  Days 19-20: Bash
