Unix command line : How to get the total size of modified files in the last 30 days
You could do this by having find output the size of each file, then total them up with awk
find . -name '*' -mtime -30 -printf '%s\n' | awk '{s+=$1} END {print s}'
Try piping the output of your working find command to du to see if the output its satisfactory. You can use the du switches -c to produce a total, and optionally -h to make it human readable.
eg:
<your command> | du -cbecomes:
find . -name '*' -mtime -30 | du -c If you only want the total line:
find . -name '*' -mtime -30 | du -c | grep "total"Produces output:
360 totaland using du -ch produces:
360K total
