How to estimate the storage size of all files not named *.[extension] on the current directory

With this sentence we can estimate the storage size of all files not named *.jpg on the current directory.

The syntax is based on Linux, for Unix compliance use:

find ./* -prune ! -name '*.jpg' -ls |awk '{TOTAL+=$7} END {print int(TOTAL/(1024^2))"MB"}'

We can change the jpg extension for whatever extension what we need

Summarize size of all files of given type in all subdirectories (in bytes)

This deals nicely with filenames containing special characters and can deal with more files than can fit on a commandline. It also avoids spawning du.

find / -type f -size +1000000000c
