Spostamento di una gerarchia Maildir sotto un'altro account

Questo script sposta tutta la posta dell'account sorgente in una sottocartella dell'account destinazione.

Uso:

sudo /tmp/sposta_maildir src_account dst_account

cat | sudo tee /tmp/sposta_maildir > /dev/null <<'EOFile'
#!/bin/bash
SRC="$1"
DST="$2"

if [ "$(id -u)" -ne "0" ]
then
        echo You must be root to run this script. Aborting.
        exit 127
fi
 
if [ -z "$1" -o -z "$2"  ]
then
        echo Usage: sposta_maildir src_account dst_account
        exit 127
fi

if [ ! -e /home/${SRC}/Maildir ]
then
        echo /home/${SRC}/Maildir does not exist. Aborting
        exit 127
fi

if [ ! -e /home/${DST}/Maildir ]
then
        echo /home/${DST}/Maildir does not exist. Aborting
        exit 127
fi

echo Moving /home/${SRC}/Maildir to /home/${DST}/Maildir/.${SRC}

cd /home/${SRC}/Maildir
for VAR in .*
do
        if  [[ "$VAR" != "." && "$VAR" != ".." ]]
        then
                set -x
                mv "$VAR" ".${SRC}$VAR"
                set +x
        fi
done
set -x
mkdir  .${SRC}
mv cur .${SRC}
mv new .${SRC}
mv tmp .${SRC}

mv .${SRC}* /home/${DST}/Maildir

chown -R ${DST}: /home/${DST}/Maildir
