Rebuilding SIS attachment links from log

[Hardy Flor]

I use this script for review. For a correct result Dovecot should not run.

#!/bin/bash

attdir="/var/files/attachments"
maildir="/var/mail"

cd "$attdir" || exit 1
find -type f -printf "%P\n" | grep -v "hashes" | sort -u 
 >"$maildir/attachments.s"
cd "$maildir" || exit 2
rm "$maildir/files.ok" "$maildir/files.fail" 2>/dev/null
for f in $(find -type f -name "m.*" -printf "%P\n"); do
   doveadm dump -t dbox "$f" | egrep "^msg.ext-ref" | while read z; do
     set -- $z
     while [ -n "$1" ]; do
       if [[ $1 == */* ]]; then
         test -r "$attdir/$1" && echo "$1" >>"$maildir/files.ok" || echo 
"$1" >>"$maildir/files.fail"
       fi
       shift
     done
   done
done
sort -u "$maildir/files.ok" >"$maildir/files.s"
diff -Nu "$maildir/attachments.s" "$maildir/files.s" | tee 
"$maildir/files.diff" | egrep "^\-"
