Code:
exec xtractall.sh

Is there some requirement to use exec on the iphone OS? What if you tried leaving that off? Normally, exec is rarely or never required.
---------------------------
Code:
After:
/var/mobile/Media/Downloads/Ac:                directory
/var/mobile/Media/Downloads/Ac.deb:            Debian binary package (format 2.0)
/var/mobile/Media/Downloads/Brc:               directory
/var/mobile/Media/Downloads/Brc.deb:           Debian binary package (format 2.0)
/var/mobile/Media/Downloads/CleanUP:           directory
/var/mobile/Media/Downloads/CleanUP.deb:       Debian binary package (format 2.0)
Pascals-iPhone:~ root# cd /var/mobile/Media/Downloads
Pascals-iPhone:/var/mobile/Media/Downloads root# ls
Ac/      Ac.deb.x/  Brc.deb*    CleanUP/      CleanUP.deb.x/
Ac.deb*  Brc/       Brc.deb.x/  CleanUP.deb*

Doesn't make sense. "After:" (from file *) shows six files / dirs. The ls shows nine. Doesn't add up. Try doing ls -l to help figure out what the difference is, why three .x dirs supposedly show up in one listing, not the other.

----------------------
Code:
Before:
/var/mobile/Media/Downloads/Ac:                directory
/var/mobile/Media/Downloads/Ac.deb:            Debian binary package (format 2.0)
/var/mobile/Media/Downloads/Ac.deb.x:          directory
/var/mobile/Media/Downloads/Brc:               directory
/var/mobile/Media/Downloads/Brc.deb:           Debian binary package (format 2.0)
/var/mobile/Media/Downloads/Brc.deb.x:         directory
/var/mobile/Media/Downloads/CleanUP:           directory
/var/mobile/Media/Downloads/CleanUP.deb:       Debian binary package (format 2.0)
/var/mobile/Media/Downloads/CleanUP.deb.x:     directory

---------------------------------------------------

If the Before: situation already has both Ac and Ac.deb.x directories, then when mv Ac.deb.x Ac runs, it does not rename Ac.deb.x to Ac, but instead moves Ac.deb.x to be a subdirectory of the existing Ac directory. The script assumes that the renamed directories do not already exist.
Code:
$ file *
dir:        directory
dir.deb.x:  directory
file.deb.x: ASCII text
$ ls dir
$ mv dir.deb.x dir
$ file *
dir:        directory
file.deb.x: ASCII text
$ ls dir
dir.deb.x

Taking into account that the final directory may already exist, and adding an ls -ld at the end:
Code:
# Remove .deb.x extension from any directory name
# DIR=/var/mobile/Media/Downloads
DIR=/tmp/xxx
echo Before:
file $DIR/*
for old_sub in $DIR/*.deb.x; do
  if [ -d "$old_sub" ]; then
    new_sub=$(echo "$old_sub" | sed "s/\.deb\.x$//")
    if [ -d "$new_sub" ]; then
      echo "$new_sub" already exists
      # take action, such as: rmdir "$new_sub"
      # take action, such as: rm -r "$new_sub"
      # take action, such as: exit
    fi
    mv "$old_sub" "$new_sub"
  fi
done
echo After:
file $DIR/*
ls -ld $DIR/*
