Example with spearfish landsat data below (tried with other data as
well):

# launch fresh-baked grass6_dev
grass65 /geo/grassdb/nc_spm_08/PERMANENT/


# one-liner using 3 bands
(echo 3; r.covar  lsat7_2002_10,lsat7_2002_20,lsat7_2002_30) |
m.eigensystem

r.covar: complete ...
 100%
Segmentation fault (core dumped)


# extra-info
# intentionally provide _4_ instead of _3_ in echo
# m.eigensystem aborts because of "incomplete input..."
(echo 4; r.covar  lsat7_2002_10,lsat7_2002_20,lsat7_2002_30) |
m.eigensystem

r.covar: complete ...
 100%
 Incomplete input file
