`di` is a highly portable program to display disk information.
It features the ability to display the disk usage in the format you prefer.
With version 4.39, a Tcl extension is now available.
It provides a 'diskspace' command that returns a dictionary with
the filesystem information.%|%
The dictionary returned is nested and keyed by the mount point.
The dictionary keys are: device, fstype, total, free, available, totalinodes, freeinodes, availableinodes, mountoptions, display.
The total, free and available space are returned as bytes.
'display' is returned when the `di` format specifier is not empty. The data returned is a list of the display items.
Any of the `di` options may be used to change the data returned in the 'display' key. See the `di` manual page for the complete list.
Example usage:
======
# assuming the diskspace extension is in the same directory as your script...
set ext [info sharedlibextension]
set lfn [file normalize [file join [file dirname [info script]] diskspace$ext]]
load $lfn
set di [diskspace -f {} /] ; # get only the basic information for root filesystem
/ {device /dev/sda1 fstype ext4 total 485893496832 free 269818650624 available 245113102336 totalinodes 30138368 freeinodes 29762805 availableinodes 29762805 mountoptions rw,errors=remount-ro}
set di [diskspace -f {up} /] ; # also get the used space and percentage used.
/ {display {201.2G 50%} device /dev/sda1 fstype ext4 total 485893496832 free 269818736640 available 245113188352 totalinodes 30138368 freeinodes 29762805 availableinodes 29762805 mountoptions rw,errors=remount-ro}
lassign [dict get $di / display] useddisplay percused
set di [diskspace -d 1 -f up /] ; # instead, get the used value in bytes.
/ {display {216074854400 50%} device /dev/sda1 fstype ext4 total 485893496832 free 269818642432 available 245113094144 totalinodes 30138368 freeinodes 29762805 availableinodes 29762805 mountoptions rw,errors=remount-ro}
lassign [dict get $di / display] usedbytes percused
set di [diskspace -f {}] ; # get information on the usual list of filesystems.

To build the Tcl extension:
Most systems:
cd C; make -e tcl-sh
Windows Cygwin:
cd C; make -e CC=gcc NO_PIE=yes tcl-sh
Windows Msys:
cd C; make -e WINAPI=T NO_PIE=yes LDFLAGS_SHARED="-static-libgcc" tcl-sh
