One of the most useful little tools for information parsing that I’ve used has
awk will allow you to pipe text through it and use
printf() function to format text as you require it to be formatted. It
also has a basic scripting language that lends further functionality, making it
an ubiquitous tool in the POSIX arsenal. Need to format a list of US States for
a Maruku table? Not a problem. Copy / Paste it into a text file and pipe it
I’ll break that line down for you.
awk to separate columns by
printf( begins the print formatting function.
%4s denotes a string padded with four spaces.
| makes Maruku interpret a table column.
%-20s denotes a left-align string padded up to 20 spaces.
$1, $2, $3 tells
printf() to use the first, second, and third columns.
It’s really pretty easy. The information goes through
stdin() and exits
stdout() as per usual, unless you specify otherwise. I highly recommend
reading more about
awk, as you’ll definitely find a use for it once you do.
