Recently I transfered a folder with big a mount of archives and something seemed to be missing, obviously I wanted to verify that the amount of files was correct and probably just like you, I couldn't find a simple Linux command to help me with this, in fact I found crazy commands like:
"echo $(($(ls -l | grep -v ^d | wc -l)-1))"
Until I found the simple and elegant "tree", if you don't have it already just run a simple:
"sudo apt-get install tree"
And then you'll have the simple response you were looking for:
"234 directories, 1786 files"
