Determine space taken by files of certain type

find . -name <pattern> -ls | awk 'BEGIN {i=0}; {i=i+$7}; END {print i}'
Just how much space are those zillions of database logs taking up ? How much will you gain on a compression rate of say 80% ? This little line gives you a good start for your calculations.

What Others Think

The awk part could be written different, so the command will be: find . -name -ls | awk '{i += $7} END {print i/1048576 "MB"}' When the variable i is used for the first time it has no value so you could use the i += writting. Or you could leave it like this, it's up to you: find . -name -ls | awk 'BEGIN {i=0} {i += $7} END {print i/1048576 "MB"}'
