#The script written by Grifter from http://forums.debian.net
#It scans your NH mailbox for deleted MH files (like ",1"), make them readable and put them
#into the trash folder which you have to create.
###########################################################################################

# Set this dir to be the location of where you want
# the files moved, be aware that this should be the
# dump for all deleted mails, it should not be an
# existing mailbox that has to compete with 'real'
# mails
UN=/home/rex/Mail/trash

# Set this dir to be the root of the mailstructure
# you want to search for ",filenames"
DEUX=/home/rex/Mail

# Check for the latest mail, stripping the padding zeroes
# (let doesn't preserve the padding zeroes, so we need to
# re-pad them later on)
VARCOUNT=`ls $UN | sed -r 's/(0*)(.*)/\2/' | tail -n 1`

# Check if it's the first run, if not we'll let the var
# iterate higher, so the next filename won't overwrite
# the previous mail

# Here we start the loop to find ",filenames", when it finds one
# it will test how many characters the current count has, first
# testing for 5 characters where no padding is needed, if the
# var doesn't have 5 chars it will test for 4, and pad one zero
# infront of the count, otherwise it will continue down the list,
# adding extra zeroes as needed, to make it 5 characters
