great script

[mikes222]

You saved my life, great script. Just 2 possible enhancements:

• It would be nice to have a switch to also include the root directory. So for example if one executes the script with ./recover.sh m/shared/mike the mentioned directory itself should also be linked if the switch is set.
• If possible please escape the ampersand-character. Example:

ln -f /var/spool/cyrus/mail/m/user/michi/Entw&APw-rfe/* /var/spool/cyrus/mail/uuid/7/k/7kzoshey6w72aqj5tanqe0a5

In this case the german umlaut-a should rather be ....Entw\&APw-rfe...

One more thing, if the directory contains many, many files: The "*" character expands the command line with each file so there may be too many characters in the command line. In this case the ln command must be done in other ways. I did it with the following command which however is slower:

find /var/spool/cyrus/mail/m/user/<user> -maxdepth 1 -type f -name '*' -exec ln -f {} . \;

Just for reference, this is my interpretation of the second part of the script.

# get path of created mailbox
NEWPATH=$(/usr/lib/cyrus/bin/mbpath $SHORT_USER)
# get original path of mailbox
OLDPATH=$SPOOLDIR$1
if ! [ -d "$OLDPATH" ]; then
    err "Old path for $MBX ($OLDPATH) does not exist, please investigate, skipping"
    continue
fi
if ! [ -d "$NEWPATH" ]; then
    die "New path for $MBX ($NEWPATH) does not exist, you missed creating a mailbox"
fi
# link it
if [ $(ls $OLDPATH | wc -l) -gt 40000 ]; then
    echo echo $(ls $OLDPATH | wc -l) items for $OLDPATH
    echo find ${OLDPATH} -maxdepth 1 -type f -name \'*\' -exec ln -f {} $NEWPATH \\\;
else
    echo ln -f ${OLDPATH//\ /\\ }/\* $NEWPATH
fi | tee rootmbx.bash
chmod 755 rootmbx.bash

echo -----
echo linkmbx.bash created, please review before executing and then run it
echo manual work:
echo 1. might be too many argument, review output
echo 2. main inbox not linked, create inbox_recovered and link the contents. See the README for details on how to do that.

remaining open issues:

• escaping german umlauts
• if the given useraccount does NOT exists and has NO subdirectories it will not be created by this script. You need to create it manually before linking the mails with rootmbx.bash
