| Today I was just curious which directory holds the deepest file on my Linux PC. | |
| The below command will print the dir with maximum depth. | |
| >find / -type d | awk -F "/" -v slash=0 '{if (NF > slash) { slash=NF; DIR=$0}} END { print DIR":"slash}' | |
| The result I got is 16 as max depth which was a ruby dir. |
