print code 3-up and syntax-highlighted for easy beach-time study

This is the setup I'm using for my largest project. It gives 357 lines per page (per side), which makes it fairly easy to carry around a significant amount of code on a few sheets of paper. Try it.

(I stick to the 80 column convention in my coding. For wider code, you'll have to adjust this.)

for i in $(seq 1 50) ; do echo Iteration $i ; done

2009-02-08 23:03:31

User: abcde

Functions: echo seq

seq can produce the same thing as Perl's ... operator.

Optionally, one can use {1..50} instead of seq. E.g. for i in {1..50} ; do echo Iteration $i ; done

sed -n '10,20p' <filename>

2009-02-08 22:34:04

User: ergut

Functions: sed

Up
Down

Print all the lines between 10 and 20 of a file

Similarly, if you want to print from 10 to the end of line you can use: sed -n '10,$p' filename

This is especially useful if you are dealing with a large file. Sometimes you just want to extract a sample without opening the entire file.

This will output the sound from your microphone port to the ssh target computer's speaker port. The sound quality is very bad, so you will hear a lot of hissing.
