One of the reasons I love Linux is the fact you can combine a few commands and do the most boring jobs in seconds, way better then manual work could have; An example ? I wanted to have a “random” file structure with not empty files. (so files with content) So I created 100 directory’s and added 10 files to each directory with random content and increasing size.  Sounds like allot of work right ?

for a in {1..100}; 
do  
  mkdir dir$a/; 
  cd dir$a; 
  
  for i in {1..10}; 
  do 
    dd if=/dev/urandom of=file_$i.log bs=1M count=$i; 
  done; 
  cd ..; 
  
done

Bam ! Although full disclaimer, bash should take the credit here ! Thx bash <3 <3 <3
