[GRASS-user] reverse output of g.mlist

[Stefan Sylla]

Dear list,

if have some Landsat 7 sets that I want to patch together to fill up the
gaps. To get things a little faster, I wanted to pipe the output of g.mlist
to r.patch so that I do not need to type in everything by hand. My problem
now ist, that g.mlist prints the raster-maps in alphabetical/numeric order.
As the cloud cover is lowest for the (numerical) last raster map, I'd like
to reverse the output of g.mlist so that the last map will be on top of the
r.patch process. I tried as follows:

The standard output of my g.mlist-pattern is as follows:
~ > g.mlist type=rast sep=, pat="*B10"
129_04720110101_B10,129_04720110117_B10,129_04720110306_B10


My aim is to reverse the output as follows
129_04720110306_B10,129_04720110117_B10,129_04720110101_B10


which I tried with:
g.mlist type=rast sep=, pat="*B10"|sort -r


But the output remains as:  
129_04720110101_B10,129_04720110117_B10,129_04720110306_B10


Any ideas about what I am doing wrong here?
