getting unstuck

[Laura Eaves]

Ok, since your shell apparently doesn't have a basedir command, here's a 
script that uses find and nested for loops and doesn't need either basename 
or basedir:

for D in `find topdir -type d -print | sort -r`; do
    (cd $D
    for F in *; do mv $F "`echo $F | sed -e 's/-/_/g'`"; done
    )
done

I think that should do it -- note it will change the names from the deepest 
files to the topmost so you won't run into problems with the directory 
names.
