Heloo all.

my r.roughness script was working fine, but today I tried to use it
and get this:

(BTW, GRASS 6.3-cvs, Ubuntu Linux 6.10)

: 221: ==: unexpected operator

GRASS_INFO_MESSAGE(2621,1): Scanning input for column types ...

GRASS_INFO_MESSAGE(2621,2): Maximum input row length: 0

GRASS_INFO_MESSAGE(2621,3): Maximum number of columns: 0

GRASS_INFO_MESSAGE(2621,4): Minimum number of columns: -1

GRASS_INFO_ERROR(2621,5): x column number > minimum last column number
GRASS_INFO_ERROR(2621,5): (incorrect field separator?)

Does this have something to do with the recent changes in parser?

The script is attached

No, changes in Ubuntu. Now it uses [d]ash as the default /bin/sh, not
Bash, and your script uses Bash specific tricks:

    east=$(echo "scale=6; $west + $grid" | bc);

either make those sh compatible,

    east="`echo "scale=6; $west + $grid" | bc`"

or change the shebang to #!/bin/bash
