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.

purge installed but unused linux headers, image, or modules

will purge: only installed apps: /^ii/!d avoiding current kernel stuff: /'"$(uname -r | sed "s/$.*$-$[^0-9]\+$/\1/")"'/d using app names: s/^[^ ]* [^ ]* $[^ ]*$.*/\1/ avoiding stuff without a version number: /[0-9]/!d

RTFM function

Same as the other rtfm's, but using the more correct xdg-open instead of $BROWSER. I can't find a way to open info only if the term exists, so it stays out of my version.

Search commandlinefu.com from the command line using the API

Search for one/many words on commandlinefu, results in vim for easy copy, manipulation. The -R flag is for readonly mode...you can still write to a file, but vim won't prompt for save on quit. What I'd really like is a way to do this from within vim in a new tab. Something like $ :Tex path/to/file but $ :cmdfu search terms

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Encode a file to MPEG4 format

Encode video.avi into newvideo.avi using the libav codec to produce an MPEG4 file with a bitrate of 800

draw matrix using dot

Find all files containing a word

shorter :p
