[GRASS5] i.group and g.mlist/tcsh problem

Hi,

with tcsh we have an annoying problem here (works fine with bash):

GRASS 5.7.cvs > i.group gr=avgroup in=`g.mlist rast sep=, pat="av*"`
Word too long.

GRASS 5.7.cvs > g.mlist rast pat="av*" | wc -l
    601
GRASS 5.7.cvs > g.mlist rast pat="av*" | wc -c
  19232

19232 characters are really not that much. Any tricks to
extend that (solution for non-root users)?

Thanks

Markus

G57cvs> i.group gr=avgroup in=`g.mlist rast sep=, pat="av*"`

Is tcsh going to take a command longer than 4096 chars long?

maybe pipe 'g.mlist sep=\n' to a file and then use a loop with head &
tail to feed 100 names at a time until done..

.. or just make a $MAPSET/group/groupname/REF file directly with awk.
Apparently just "$map $mapset\n"

...mhhh...

Thanks for the info.

Maybe the best trick is to tell the sysadmin to change to bash login shell?
