Da ridere, se non fosse da piangere. Da indignarsi, se contro l’ignoranza bastasse l’indignazione.

nessun sentire è mai troppo lontano.

– Rainer Maria Rilke

Ho sempre odiato i porci ed i ruffiani
e quelli che rubavano un salario
i falsi che si fanno una carriera

Did you ever need to look up a file and had no idea where it could be? Or did you want to know how a directory and its sub-directories are structured, but didn’t have any overview? This is where tree comes in.

By running tree you get a nicely looking directory tree, containing the current directory and all the sub-directories.

To install tree on Arch, use the command:

#pacman -S tree

Handy, isn’t it? But there’s more to it! If you look up the man page you see that, as an example, you can append the -lflag to follow symbolic links or append the -fflag to print the relative file path, which is useful if you need the relative path in your code base. Additionally, if you execute treefor a large directory with numerous sub-directories you may limit the depth of the sub-directory traversal to e.g. 2 levels via the tree -L 2 .

From Python 3.6 (and onwards) you can use underscores to make numbers easier to read.

Let’s look at an example:
