dfeta -- Disk Freespace ETA Estimation

SYNOPSIS

dfeta sample dfeta -d /usr/bin/df dfeta dfeta -h

DESCRIPTION

dfeta samples disk freespace information on regular periods. then it can show (rough) estimate time when disk/device will be full. to sample current status (free space) on all local filesystems: dfeta sample to get estimates for the sampled filesystems: dfeta eta or just: dfeta 'dfeta sample' is supposed to be run on regular basis (for example from the crontab). to attach it to every hour in the crontab you need to enter this line: 0 * * * * /usr/local/bin/dfeta sample dfeta holds current statistics in: $HOME/.dfeta/data each 'sample' command will backup previous data file.

EXAMPLE OUTPUT

Device | Mount point | Estimate full at | Full in | /dev/sda2 | / | [never] | [n/a] | /dev/sdb2 | /third | Fri Sep 3 2010 | in 2 months | /dev/sde2 | /home/cade/back | Mon Apr 14 2011 | in 9 months |
