AWS Route53 hosted zone export

Frustrated with the manual domain migration process AWS has, I unsuccessfully tried to install cli53, route53-transfer. I instead wrote this oneliner to ease the export (which is not supported via the AWS console ATM). The output can be easily pasted into the "Import Hosted Zone" dialog in Route53. SOA/NS records are excluded since they cannot be automatically imported. Show Sample Output

Count all files in directories recursively with find

Counts the files present in the different directories recursively. One only has to change maxdepth to have further insight in the directory hierarchy.

Efficient remote forensic disk acquisition gpg-crypted for multiple recipients

Acquires a bit-by-bit data image, gzip-compresses it on multiple cores (pigz) and encrypts the data for multiple recipients (gpg -e -r). It finally sends it off to a remote machine.

Check a server is up. If it isn't mail me.

For some reason the 2&>1 does not work for me, but the shorter stdout/stderr redirection >& works perfectly (Ubuntu 10.04).

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Share Your Commands

Check These Out

Email yourself after a job is done

This is a two part command that comes in really handy if you're running commands that take longer than you're willing to wait. The commands are separated by the semicolon(;) The first command is whatever you're attempting to do. The second commands emails you after the job completes.

Uptime in minute

Want to run scripts/programs in the system after starting X minute [ For letting the system to free ]? This will give uptime in minute.

Kill any lingering ssh processes

Also ignoring "sshd" server is necessary since you should not kill ssh server processes.

See system users

Paste hardware list (hwls) in html format into pastehtml.com directly from console and return URI.

In this Linux box i need to become root to get the complete hardware list, so either become root before or call it with sudo as i did, your choice.

Annotate tail -f with timestamps

Update zone file Serial numbers

Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc. Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this. Make sure your server's date is correct, otherwise insert your own serial number. $rndc reload should usually follow this command.

Search some text from all files inside a directory

back ssh from firewalled hosts

host B (you) redirects a modem port (62220) to his local ssh. host A is a remote machine (the ones that issues the ssh cmd). once connected port 5497 is in listening mode on host B. host B just do a ssh 127.0.0.1 -p 5497 -l user and reaches the remote host'ssh. This can be used also for vnc and so on.

Touch a file using a timestamp embedded in the file name.

tstouch takes two arguments: a filename containing a timestamp, and an extended regular expression with the parenthesized section matching a timestamp of the form YYYYMMDDhhmm or YYYYMMDDhhmm.ss. It then touches the file with that timestamp.

Stay in the loop…
