you should provide a target, to work on

this can be

-package
The program works on designed installed rpm package.
-file
The program works on designed file, which should be a part from a rpm package.
-rollback
The program works from designed log file, and rollback (revert) the changes.

OPTIONS

-help
Print a brief help message and exits.
-man
Print the manual page and exits.
-version
Print the program release and exit.

-batch
The program works without interactive questions (the default mode is interactive)
-dryrun

-file
The program works on designed file, which should be a part from a rpm package.
-rollback
The program works from designed log file, and rollback (revert) the changes.
-all
If no attribute are specified, the program work on all, as if this flag is set. It is the same as : -user -group -mode -time -size -md5
-user
This is the owner attribute
-group
This is the group attribute
-mode
This is the file permissions : read-write-execute for user, group, other
-time
This attribute is the date of last changes on file.
-size
This is the file size attribute. This is a ``read-only'' attribute : it can not be restored by the program.
-md5
md5 is a checksum (a kind of fingerprint) : if the file content is changed, the checksum will change too. A difference on this attribute means the file content was changed. This is a ``read-only'' attribute : it can not be restored by the program.

USAGE

the rpm command to control changes

rpm -V rpm

same effect (just display) but more detailed (display values)

rpmrestore -n -package rpm

interactive change mode, only on time attribute

rpmrestore -time -package rpm

interactive change mode, on all attributes except time attribute

rpmrestore -all -notime -package rpm

batch change mode (DANGEROUS) on mode attribute with log file

rpmrestore -batch -package rpm -log /tmp/log

interactive change of mode attribute on file /etc/motd

rpmrestore -mode -file /etc/motd

interactive rollback from /tmp/log

rpmrestore -rollback /tmp/log

batch rollback user changes from /tmp/log

rpmrestore -batch -user -rollback /tmp/log

CONFIGURATION

the program can read rcfile if some exists. it will load in order

/etc/rpmrestorerc

~/.rpmrestorerc

.rpmrestorerc

In this file,

# are comments,

and parameters are stored in the following format : parameter = value

example :

verbose = 0

dry-run = 1

batch = 0

NOTES

you should be superuser to restore attributes, other users can only check changes

on batch mode, we recommend to use log file
