Script to echo "File permissions or ownership changed from required " when accidentally changed.
Hi All,
I have to work in the late nights some times for server maintenance and in a hurry to complete I am accidentally changing ownership or permission of directories
which have similar names ( /var in root and var of some other directory ).
Can some one suggest me with the logic or already available script by which the change in ownership or permission of a directory can be tracked from previous state..

dohash(8) System Manager's Manual dohash(8)
NAME
dohash, undohash - Hashes or unhashes IMAP configuration directories
SYNOPSIS
/usr/sbin/dohash [-f] [-h] [-i]
/usr/sbin/undohash
OPTIONS
The following options are available only for the dohash command: Forces the hashing process to continue even if the command encounters
errors. Prints a usage message for the command. Runs the hashing process interactively.
DESCRIPTION
The dohash command converts the IMAP configuration directories from the format for older versions of the Cyrus IMAP4 Revision 1 server to
the new format for Version 1.6.1 or higher.
Starting with Version 1.6.1 of the server, the IMAP user files in the quota and user directories are stored in a through z subdirectories,
sorted by the first character of each user name. This arrangement reduces the number of entries in a given directory and consequently
increases performance and scalability. The dohash command creates the a through z subdirectories and sorts the existing IMAP files as
described; the undohash command reverses this process, in case you need to revert to a previous version of the server.
You can optionally sort the users' directories in the IMAP mail spool in the same manner if you enable the hashimapspool option in the
/etc/imapd.conf file before invoking the dohash command. See imapd.conf(4) for more information.
Note that you must be logged in as the imap user to use the dohash command; otherwise, the newly-created subdirectories will not have the
proper ownership.
EXAMPLES
The following example shows output from the dohash command: # /usr/sbin/dohash configuration directory /var/imap... hashing user directory
hashing quota directory done hashing
In this example, the configuration directory is /var/imap; therefore, you could check that the dohash command has successfully hashed the
directories by using the ls command as follows: # ls /var/imap/quota /var/imap/user /var/imap/quota: a b c d e f g h i j k l m
n o p q r s t u v w x y z
/var/imap/user: a b c d e f g h i j k l m n o p q r s t u v w x y z
The slash () indicates line continuation.
FILES
Configuration file for the IMAP server. Specifies the location of the IMAP configuration directory.
