Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

get diskusage of files modified during the last n days

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

What others think

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.
