easier:

for CMD in `\ls -1 "$GISBASE"/scripts/?\.*` ; do
  ash -n "$CMD"
done

/usr/local/src/grass/grass63/dist.i686-pc-linux-gnu/scripts/i.spectral:
252: Syntax error: Bad substitution
/usr/local/src/grass/grass63/dist.i686-pc-linux-gnu/scripts/r.tileset:
258: Syntax error: Bad for loop variable


So i.spectral includes a Bashism too. It is limited to the COORD[]
array, so probably not too hard for someone to fix that.

r.tileset covered in another email to follow.
