If you spend all day editing in vi then switching your fingers to Emacs mode just for the command line can be difficult. Use set -o vi in your bash shell and enjoy the power of a real editor.

sudo netstat -punta

Functions: echo sleep

This will ring the system bell once if your script exits successfully and twice if it fails. So you can go look at something else and it will alert you when done. Don't forget to use 'xset b [vol [pitch [duration]]]' to get the bell to sound the way you want.

pkill -U MYWIFE

User: gracenotes
Functions: tr

Reads psuedorandom bytes from /dev/urandom, filtering out non-printable ones. Other character classes can be used, such as [:alpha:], [:digit:] and [:alnum:]. To get a string of 10 lowercase letters:

tr -dc '[:lower:]' < /dev/urandom | head -c 10

(on destination machine) nc -l 1234 > whatever; (on source machine) nc destination 1234 < whatever;
2009-02-05 21:35:08

Einstein's razor: As simple as possible, but not simpler.

On the destination machine netcat listens on any port (1234 in the example) and sends anything it receives into a file or pipe. On the source machine a separate netcat takes input from a file or pipe and sends it over the network to the listener.

This is great between machines on a LAN where you don't care about authentication, encryption, or compression and I would recommend it for being simpler than anything else in this situation. Over the internet you should use something with better security.

tar's directory and sends to netcat listening on port 10000

On the client end:

netcat [server ip] 10000 | tar xfvz -

This will send it over the network and extract it on the clients machine.

Replaces A with B in binary file "orig" and saves the result to "new". You must have the hex representations of A & B. Try od: echo -e "A\c" | od -An -x

Scan pages in, clean them up in an image editor, save to individual files. Use this command to convert each page to PDF. Combine in Acrobat Professional, and use the built-in OCR with the "Searchable Image (Exact)" option. Gives excellent image quality and file size (avoids awful JPEG image recompression that Acrobat and other OCR systems tend to do.)

Use this to turn a page with snippets of equations into vector paths that Adobe Illustrator can handle without choking on font embedding and substitution issues. Good for keeping fonts consistent when labeling charts and diagrams. Also good for embedding formulas into diagrams.
