get diskusage of files modified during the last n days

sudo find /var/log/ -mtime -7 -type f | xargs du -ch | tail -n1
get diskusage of files (in this case logfiles in /var/log) modified during the last n days: sudo find /var/log/ -mtime -n -type f | xargs du -ch n -> last modified n*24 hours ago Numeric arguments can be specified as +n for greater than n, -n for less than n, n for exactly n. => so 7*24 hours (about 7 days) is -7 sudo find /var/log/ -mtime -7 -type f | xargs du -ch | tail -n1
Sample Output
$ sudo find /var/log/ -mtime -7 -type f | xargs du -ch | tail -n1
25M     total

or

$ sudo find /var/log/ -mtime -7 -type f | xargs du -ch | grep total
25M     total

you don't always have to use xargs: find /var/log -mtime -7 -type f -exec du -ch {} + | tail -n1

Alternatively: sudo find /var/log -mtime -n -type f -exec du -ch {} + | tail -n1 This will also execute du only once.
