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

find out how much space are occuipied by files smaller than 1024K

The command gives size of all files smaller than 1024k, this information, together with disk usage, can help determin file system parameter (e.g. block size) or storage device (e.g. SSD v.s. HDD).

Note if you use awk instead of "cut| dc", you easily breach maximum allowed number of records in awk.

Alternatives

There is 1 alternative - vote for the best!

find dir -size -1024k -type f -print0 | du --files0-from - -bc

The original didn't use -print0 which fails on weird file names eg with spaces.

The original parsed the output of 'ls -l' which is always a bad idea.

Know a better way?

If you can do better, submit your command here.

What others think

Would fail if filenames contain spaces or other junk. Better to use -print0 with find and -0 with xargs.
