I don't need to check connectivity but if config files are the same in certain directories. I am also not trying to sync them exactly the config files will have different IP addresses in them and different database names, this is why I can't just use rsync but was trying to hash something out that would tell me if they are different and list out the differences through making a couple of files and then doing a compare. Perhaps rsync will do this but I didn't think so.
So the script that you are hoping to create just gives you a list of files that need to be investigated further; it doesn't sync files. Isn't that exactly what:
The first time through it is likely to give you lots of false positives due to timestamp differences. But if you use rsync to synchronize those false positives (to sync the timestamps) and files that really need to be synced, subsequent runs should give you a greatly reduced list of files on which you actually need to perform your detailed md5sum checks.
And, obviously, if there are intentional IP and database name differences in some of your config files, md5sum isn't going to help you determine if there are also other differences in those files that shouldn't be present or that should cause a more complicated partial sync.
Hi, I'm writing a shell script that calls a few commands that prompt the user for two simple yes/no questions. if the answers are consistent (the first is a yes, the second is a no), what would my expect script look like? Google is only giving me answers for scripts where I telnet or ssh. right now... (3 Replies)
And not to start. I can compare files, that's easy. The problem is that I compare files in a directory, and check if these files exist in another directory. The problem is that the file names are not the same. So I have to compare with "md5sum" or something similar. How I can do?
All this in... (7 Replies)
I was wondering if anyone could provide some assistance. I trying to run an expect script within bash and get the results of a variable called RESULT.

I'm having trouble with some automated sftp pulls. I'm using expect inside bash scripts and spawning SFTP. Some times the expect seems bog down.

I'm trying to think of a way to compare two boxes and make sure their files will be the same. There may be extra files on one side and some on the other.
I also need to make sure the file content is identical.

mrb
MRB(8) System Manager's Manual MRB(8)NAME
mrb - manage incremental snapshots with rsync/make.
SYNOPSIS
mrb command
DESCRIPTION
mrb is a simple aid to creating efficient incremental snapshots of a set, or sets, of directories whenever that may be required. It may be
used as part of a regular automated backup regime, or for manually checkpointing changes at convenient points in time.
COMMANDS
The following commands are recognised (where 'MODULE' is the name of one of your snapshot definitions):
new-MODULE
Create a skeleton definition for a new snapshot 'MODULE'.
dest-MODULE
Create the destination dir for 'MODULE'. This directory must exist to create a snapshot.
snap-MODULE
Create a snapshot of 'MODULE'.
sync Create snapshots of all defined modules. If run as root this may be configured to include the modules of other users too (see
MRB_SYNC_USERS in ~/.mrb/defaults).
help Show mrb's own help text.
CONFIGURATION FILES
Per-user configuration
The following files may be used to specify global and local configuration options.
/etc/default/mrb
system default configuration.
~/.mrb/defaults
per-user configuration.
Per-user options
The following options control behaviour for all of a user's modules.
MRB_SNAPSHOT_LOG
An optional file path where transfer details will be recorded. If unset these details will not be logged.
MRB_SYNC_USERS
A space separated list of users whose modules should be included in a sync. This is mostly only useful for root, as mrb will assume
the identity of each user before creating snapshots of their modules. If unset, only the invoking user's modules will be sync'ed.
MRB_CONFDIR
An space separated list of the directories to search for module definition (*.mrc) files. They will be searched in the order given,
with new modules added by default to the last one listed. There should be few reasons to change the default value.
Per-module configuration
The default MRB_CONFDIR value will search for module definitions in:
/etc/mrb/*.mrc
~/.mrb/*.mrc
Those created by new-MODULE will be placed in this latter location by default.
Per-module options
In each case module below is the name of the particular module that the value set should apply to. These options should be defined in a
file named module.mrc.
module_SRC
A space separated list of the files and (top level) directories to include in the snapshots for this module.
module_DEST
The directory root where snapshots of module should be stored.
module_INCLUDE
An optional list of rsync(1) include patterns.
module_EXCLUDE
An optional list of rsync(1) exclude patterns.
module_FILTER
An optional list of rsync(1) filter patterns.
module_FILTER_FILE
An optional filename for rsync(1) dir-merge filtering support.
module_RSYNC_OPTIONS
Optional additional rsync(1) options to pass verbatim when it is invoked.
module_PRECOMMAND
An optional shell command to invoke just prior to creating a new snapshot. If the command does not return a successful exit status,
then the snapshot creation will be aborted before it begins. It may be used to mount removable media or similar.
module_POSTCOMMAND
An optional shell command to execute after making the snapshot. It will not be called if the snaphot creation failed at an earlier
stage, and its return status may halt a sync operation if it fails with more modules still to process. It may be used, for example,
to unmount removable media again.
module_USER
An optional user name to check that mrb is running as before performing a snapshot. This can be used to ensure you have the correct
permisson to access the files being mirrored before you get too far.
SEE ALSO rsync(1), make(1).
