hello dovecot@dovecot.org:

I want to see the contents of dovecot.index.cache .  Is there any command can make it become visible character displayed ?

strings(1); for example: strings mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.cache

For details see: http://wiki2.dovecot.org/IndexFiles#Cache_file

...

the command idxview can displayed doveoct.index and logview can dispalyed dovecot.index.log but it seems no command to displays dovecot.index.cache for us.

Using idxview and logview indicates the you are using Dovecot v1.x. You should consider to update to a more recent AND better supported version.

thank you Timo Sirainen: is that The contents of the dovecot.index file containing the content of index.cache or they are the same one ? It seems that dovecot.index is major.

Looking at dovecot.index also displays dovecot.index.cache contents. (The cache file is unusable without dovecot.index.)

I mean when you run "idxview dovecot.index”, it actually opens both dovecot.index and dovecot.index.cache (and also dovecot.index.log) and combines all of their contents and displays the merged output. dovecot.index contains only pointers inside the dovecot.index.cache file, but without these pointers the dovecot.index.cache isn’t very usable.
