disk_usage does not work

[anlek]

I believe that the actual call for usage fails

Line 21 in disk_usage.rb
usage = df -P | grep -i " #{self.mount_point}$" | awk '{print $5}' | sed 's/%//'
should be
usage = df -P | grep -i #{self.mount_point} | awk '{print $5}' | sed 's/%//'

At least that's what I think it should be.

This works for me on OSX and Debian Linux. What operating system are you on? The reason that a space is included in the regex is so that a mount_point of /rw would not accidentally match something like /lib/init/rw.

Actually, I might have been wrong. I tested the command on Ubuntu and it didn't return a correct result and after I read a few blogs and tested it again a few weeks later, it worked fine. So please close off the issue.

I have the same problem than anlek has before.

Ubuntu 10.4

$ df -P | grep sda1
/dev/sda1             19610300   3112624  15700760      17% /

Actual regex:
$ df -P | grep -i " /dev/sda1$" | awk '{print $5}' | sed 's/%//'
$ (none results)

Modified regex:
$ df -P | grep -i "^/dev/sda1 " | awk '{print $5}' | sed 's/%//'
$ 17

Thanks for your work

I don't know if it could be a good idea to modify the valid? method so it could test that the regex responds with not empty result.
