backup-copy
backup-copy - my backup script - using this, I can keep a backup at a cost of only about 2Mb/day. Uses the hard-linking power of rsync(1)
Usage: backup-copy [OPTION...] [--] [repository]
Backup interesting files as set in the config file.
Simple usage:
backup-copy # does a backup - put this in cron!!
backup-copy -l # shows what backups are available
backup-copy --delta :now -v # shows what's changed since last backup
backup-copy -f /etc/passwd # show distinct versions of that file
Details.
Backups will go to:
<repository>/backup-copy/$HOST/YYYY/MM/DD-hh_mm
with <repository> in the form of either 'hostname:directory' or
'directory' (default is /var). 'directory' must already have a subdirectory
'backup-copy/$HOST' otherwise the --init option can be given to create it.
If using a remote system as <repository>, you need to have the ssh
key pushed to the remote for login without password.
Environment parameters can be set in the config file as follows:
MUST_BE_ROOT="yes" # to restrict to root (or "" or unset)
DEFAULT_DESTINATION= # repository to use (overridden by a repository on the
command line)
TEST_FILE= # invariant inoded file to test consistency
EXCLUDES= # list of rsync patterns to exclude
INCLUDES= # list of rsync patterns to include
EXPIRE= # remove backups older than this number of days
KEEP_MONTHLY= # only keep one backup per month of anything older than this
Options:
-b, --brief On all diff operations, report only whether the
files differ, not the details of the differences.
-c, --config=config-file override the config file (the default is the first
in the list:
/home/bhepple/.config/backup-copy.achar
/home/bhepple/.backup-copy.achar
/home/bhepple/.config/backup-copy
/home/bhepple/.backup-copy /etc/backup-copy)
Default is '/etc/backup-copy'.
-C, --check-links=dates don't backup - just check the backup tree ensuring
that hard links are correct (this can be slow,
particularly on a remote repository). The argument
'dates' is in the format
'[first|last|prev|YYYY/MM/DD-HH_MM[,last|prev|YYYY/MM/DD-HH_MM]'.
The dates may be wildcarded (with * and ?) but if
two dates are specified, the first may not be
wildcarded. The dates 'first', 'last' and 'prev'
are expanded to the first, last and previous
backup dates respectively. If only one date is
given, then all files in the backup repository are
compared to the files under that date directory.
If two args are given then the comparison is
between the first date directory and the second
one(s) - but intermediate dates are not
interpolated. eg to check the latest backup
against the previous one, use 'prev,last'. Note
that when duplicates are found then the new link
is created using the first date directory as the
base.
--debug even more verbosity
--delta=dates don't backup - just diff two backups. The dates
are given as '[date1][,date2]' with a date in the
format 'first|last|prev|now|YYYY/MM/DD-HH_MM' eg
'2011/01/18-21_13,2011/01/26-21_13'. A blank date
means the last (latest) backup. The dates 'first',
'last' and 'prev' are expanded to the first, last
and previous backup dates respectively. A date of
'now' compares against the live system (this can
be quite slow on a remote backup as the files must
be downloaded before the diff is done. Fast on a
local backup.) Thus to compare the live system
with the latest backup use ',now'. You can get
the list of available backups with the --list
option. The number of files that differ is
returned in the exit code.
-D, --diff do a diff after the backup
-f, --file-vers=file don't backup - just list the distinct versions of
'file' available in the repository with their
sizes. Note that this isn't terribly useful if run
on a directory or symbolic link.
-H, --host=host override the host name. Default is 'achar'.
-i, --init initialise repository if necessary
-l, --list don't backup - just list the backups in the
repository
-n, --dryrun dry run - just print what would be done
--progress show progress
-q, --quiet be quiet
-w, --warn warn about suspicious filenames
-h, --help print this help message
-V, --version print version and exit
Mandatory or optional arguments to long options are also mandatory or optional
for any corresponding short options.

r
r - run a command with sudo or popup a root xterm
Usage: r [OPTION...] [--] [command] Run 'command' as root via the 'root' program if available else sudo. If command is not given then start up a root shell. You might want to customise the XTERM setting in this script if you want something different from "myterm --" Note that you need to take care of the /etc/sudoers file by adding the NOPASSWD:: flag to your line. Ideally be a member of wheel group and: %wheel ALL=(ALL) NOPASSWD: ALL Options: -v, --verbose be verbose -X, --use-x prefer X instead of console -h, --help print this help message -V, --version print version and exit

given then a 'camel case to underscore' replacement will be done eg CamelCase
-> camel_case. Does not touch .svn, 'cscope*', 'TAGS' or '*~' files. It's often
a good idea to use -n,--dryrun and copy, paste and modify the command before
running it manually.
Options:
-c, --allc-files only looks at *.[ch], *.cxx, *.hpp & *.cpp files

-h, --help print this help message
-V, --version print version and exit

Usage: v [OPTION...] [--] file(s)
View a file using an application appropriate to its type depending on whether
you're running from a console or under X. Prefer console apps over X.
Does not rely on lesspipe.sh
Passes all files to the viewer if it makes sense to do so. Also, only the first
file is inspected to decide how to view/edit/exec.
Options:
-a, --all view all media files under PWD (recursively)
-e, --edit edit or exec instead of view (default if run as
'x')
-n, --dryrun just print what would be done
-v, --verbose be verbose
-x, --use-x prefer X instead of console
-h, --help print this help message
-V, --version print version and exit

Usage: vnc [OPTION...] [--] [user@]hostname[:display#|::port]
Connects to the first existing vncserver or x11vnc on the remote if any. If
none, runs vncserver on the remote and vncviewer on the local, using the
geometry and dpi of the local to make fonts look right.
Options:
-d, --dont-keep don't keep the remote session going.
-D, --desktop create a remote desktop link to the :0 desktop
with x11vnc
-g, --geometry=WxH geometry WxH (or 'full' to use the same as the
current screen). Default is 'full'.

for future use. Default is 'ask'.
--kill=display kill remote display
-l, --list list vncports on remote
-n, --dname=desktop-name desktop name to pass in VNCDESKTOP to
~/.vnc/xstartup eg :0
-N, --new don't look for an existing vnc session on the
remote - create a new one.
-p, --sshport=port port to use for ssh
-v, --verbose be verbose
--via use --via $HOST localhost:$VNCPORT
-h, --help print this help message

Requires zenity.
Usage: xcheck [OPTION...] [--] <x-command>
Run a X command capturing stdout and stderr. If it gives an error, popup a
viewer with the messages.

Also removes any crufty xwin-utils backup file
/home/bhepple/.local/share/xwin/$WINDOW_ID.
Options:
-f, --force always display output
-v, --verbose be verbose
-w, --watch=time time to watch the app. 0==forever. Default is '5'.
