[GRASS-user] Renaming many files with one command

[Vincent Bain]

Weird... sorry, I just notice you meant to rename rasters, not vectors.
Anyway, here it works as well with rasters

        GRASS 7.3.svn (local):~ > g.list rast
        open_h_aze
        open_h_qsd
        GRASS 7.3.svn (local):~ > for i in `g.list type=raster
        pattern=open_h_*`;do g.rename rast=$i,`echo $i | sed
        s/open_h_/blocked_h_/g`;done
        Rename raster <open_h_aze> to <blocked_h_aze>
        Rename raster <open_h_qsd> to <blocked_h_qsd>
        GRASS 7.3.svn (local):~ > g.list rast
        blocked_h_aze
        blocked_h_qsd
        GRASS 7.3.svn (local):~ >

Is there something in the raster names suffixes that could be hurting
sed ? could you provide a g.list rast output ?

Anyone else may suggest an explanation?

Bye,
Vincent.
