PARTITION DIFFERENCES QUERY
Since many changes can occur to a partition over time, you may only
want to look for specific types of changes. This window allows one
to search for specific changes.
General Fields
Find Filenames like
Use this field to specify file names to use in the search pattern.
The file names can contain the standard UNIX wild card matching
characters `*', `?' and `[ ]'. This field will accept more than one
entry. Leave a blank space between each unique filename for multiple
entries. This is a good mechanism to use if you only want to check
for changes in a certain area of a partition.
Skip Filenames like
This is the opposite of Find Filenames like. The filenames entered
here create an exclusion list. Any filename entered here will NOT be
matched by the search. This field uses the same format as the
previous field. This is a good way to ignore files that change on a
regular basis and omit unnecessary entries in the report.
Owner Names
Use this field to find only those files whose owners match the names
of the users entered. This field will accept more than one entry.
Leave a blank space between each unique owner for multiple
entries.To exclude any files owned by certain users, place a !
before those usernames. For example:
root bin uucp Only files belonging to users root, bin, or
uucp
!root !bin All files except those belonging to users
root and bin
Group Names
This field is similar to the Owner Names field, except you can
specify user group names to use (or exclude) instead of user names.
Min. File Size
Use this field to limit the search to files larger than a certain
size. The default unit is bytes, but by appending one of the letters
k, m, or g, the corresponding unit size of kilobytes (KB), megabytes
(MB) or gigabytes (GB) will be used. This can be useful when you are
looking for log files growing out of control.
Max. File Size
This field is similar to the Min. File Size field, except you can
specify the maximum file size allowed in the search.
New Files
Click on the Yes button (the default) to search for new files which
did not exist in the previously saved snapshot.
Include contents of new/lost dirs
When Enlighten searches for new or lost files and it comes across a
new/lost directory, this selection determines if the contents of the
new/lost directory should be included in the search. Click on the
Yes button (the default) if you want Enlighten to look at the
complete contents of the new/lost directory in this case. Otherwise,
click on the No button to just put the name of the new/lost
directory into any report results.
Lost Files
Click on the Yes button (the default) to search for files which did
exist in the previously saved snapshot and now no longer exist.
Attempt to determine renamed files
Sometimes, files are renamed. Normally this is considered to be a
creation of a new file and the loss of the old one. Click on the Yes
button (the default) if you want Enlighten to attempt to determine
if the file has been renamed or not.
This check is not fool proof; it will only find a file being renamed
(moved) within the same directory in which it was originally found.
Altered Files
Click on the Yes button (the default) to search for files which have
changed since the previously saved snapshot. There are many
different ways a file can change. These can be selected and/or
limited by using the following fields. The default value for all of
these fields is also set to Yes.
Size
Use this filed to search for files that have either increased or
decreased in size and/or to search for changes within certain
ranges. In the second case, you may enter the range of size changes
that should be searched for in the corresponding Ranges field.
Each size range should be separated by a blank space. The range can
be prefixed by a minus (-) sign to denote a decrease in the size or
a plus (+) sign to denote an increase in size. If no sign is given,
then an increase in size is assumed. A range has the following
format:
[+/-]<minsize>[<unit>]-[<maxsize>[<unit>]]
The square brackets ([]) denote that the field is optional. The
fields are:
+ Search for files that have increased in size
- Search for files that have decreased in size
<minsize> The minimum size that file has changed in size
<maxsize> The maximum size that file has changed in size
<unit> The unit of size, with the possible units being:
b Bytes
k Kilo bytes
m Mega bytes
g Giga bytes
% Relative increase in size in terms of per cent
The following are all valid range examples:
1000 File which increased in size by 1000 bytes
-2k File which decreased in size by 2 Kb (2048 bytes)
10% File which increased in size by 10 percent
100-10k File which increased by 100 bytes but not more than 10 Kb
-10k-2m File which decreased in size by 10Kb but not more than 2Mb
User Ownership
Click on the Yes button to search for files that have changed user
ownership. Sometimes you may want to focus on changes in ownership
for just a few users or a specific group of users (e.g., chown to
root). In this case, you can specify those entries in the
corresponding Ranges field. Leave a blank space between each unique
username or user ID (UID) for multiple entries.
Group Ownership
This field is similar to the User Ownership field, except you can
specify user group names or group IDs (GIDs) to use instead of user
names or user IDs (UIDs).
Mode
Click on the Yes button to search for file permission changes. If
you only want to look for specific mode changes (e.g., new setuid
programs), you can specify those entries in the corresponding Ranges
field. Leave a blank space between each set of mode changes for
multiple entries.
You can use two formats to search for specific mode changes:
[+/-]<numeric mode>
[+/-]<who><modes>
Use the first format to search for added or lost permissions
followed by UNIX style octal <numeric mode>. Enlighten will search
for files that have had one of the specified bits changed in the
file permissions, e.g., use +007 to look for any gaining of
permissions for the other user type. Only experienced UNIX
administrators should use this format.
Use the second format to search for where a type of user (<who>)
and/or a type of mode (<modes>) permissions were added or lost.
The <who> permission values are:
u Look for changes to the user's permissions
g Look for changes to the group's permissions
o Look for changes to the others' permissions
a Look for changes to any of these permissions (user, group,
and other). This is the default value.
The <modes> permission values are:
r Look for changes to the read permissions
w Look for changes to the write permissions
x Look for changes to the execute permissions
s Look for changes to the setuid permissions
t Look for changes to the sticky bit permissions
The following are examples of the second format:
+orwx Look for any gaining of permissions for other user types
+s Look for any files gaining setuid/setgid privileges
-ax Look for any loss of executable permissions for all user types
Updated
Updated files are files that have been modified without having the
size of the file increase or decrease. This often happens to
database files where data in the middle of the file is replaced with
new data. Click on the Yes button if updated files should be part of
the search.
Accessed (read)
Every time a file/program is read or executed, the access date is
updated. Since many files are typically read or executed between
snapshots, the list of read files may become quite long. Click on
the No button if read files should not be included in the search.
Buttons
Execute Search
The search criteria may use one or any combination of the above
fields. Once you've entered your search criteria, click on the
Execute Search button. The List of Changed Files window will appear
with a list of the files which met the criteria, as shown in the
example below.
As mentioned previously, disk snapshot comparisons are time
intensive operations and this may take a while.
From here, you can execute more commands such as edit, backup, and
chown to manipulate the displayed files' characteristics. See "File
List" on page 5-31 for more details on using this window and "View
Files" on page 5-9 to use its buttons.
Clear Fields
Click on this button to clear the existing choices in all fields.
Close
Click on this button to discard any changes and close the window.
