A mix of things...
zdiffwalk walks through snapshots, showing you zfs diff output.
Usage: zdiffwalk dataset
Once running, you can nagivate using:
j next pair
k previous pair
l display a list of snapshots
g go to a specific point in the list
z zoom
q quit
cleanupdates tests hash values of files downloaded by freebsd-update
and deletes any files who fail their hash. Obviously, it requires root
privileges to delete anything. If run as !root, it will show warnings.
Usage: cleanupdates
(yes, that's it.)
voicemailpasswordcheck does basic sanity checking for Asterisk VM password changes. Add or comment rules as you see fit. Pull requests are welcome.
To use this, add the following to /etc/asterisk/voicemail.conf:
[general]
externpasscheck=/usr/local/bin/voicemailpasswordcheck
(or add to the section if it already exists.) Then .. put the file where you think it should go. :-)
mailqgrep helps you search through your Sendmail maillogs.
Usage: mailqgrep [options] [daterange] searchstring
where options are any of:
-h this help
-d include debug output (there isn't much of it)
-p pretty-print (indents et al)
-q quiet (not implemented)
-v verbose (show search string, default if on tty)
and where daterange is blank for the current day, 0 for yesterday,
1 for the day before, etc. Assuming you're rotating logfiles daily.
grab fetches files from a remote server, perhaps safely.
grab -h
grab [-div] [user@]host:file ...
For each file that grab copies, the target location is tested
for permission and available space. If tests for any files fail,
then no files are copied and temporary files are removed.
dedup deduplicates files with hard links
dedup -h
dedup [-nv] [dir/ ...]
Deduplicates all files in given directories using hard links.
File similarity is based on a hash calculated with b2sum or md5.
Older files are hardlinked to newer files.
narp named arp
narp
narp -g
Provides modified `arp -an` output, with names from /etc/ethers.
When run interactively or with `-g`, uses vt100/xterm/ansi codes
for boldface.
sshswitch ssh connections via the best means possible
sshswitch [ip address] [command line]
Gets used by openssh ProxyCommand to connect directly to an IP
if that IP is on the local network (i.e. is in the ARP table),
or run a command to connect to it otherwise.
nrmlz normalize IP and MAC addresses
nrmlz [address]
Returns the address you provided in lower case, leading zeros
stripped from IPs and added to components of MACs.
