Since procps 3.3.10, free does not output the "-/+ buffers/cache" line anymore. On the other hand, the data from it can be calculated from the memory values, so just do the calculation manually (with awk).
This is the third rewrite of the virt-df program. It very much
follows the outline of the Perl program which this replaced in
libguestfs 1.7.14.
main.c - main program
domains.c - dealing with libvirt, only used if libvirt is around
at compile time
df.c - getting the stats from libguestfs
output.c - writing the output, CSV output
virt-df.h - header file
Note this also uses the shared options parsing code in
'fish/options.[ch]'.
