Comment on BASH: Split a string without ‘cut’ or ‘awk’ by Anon

Thuktun: If you double the % or #, then it matches as few as it can instead of as much as it can. Example:

> T=a,b,c,d
> echo ${T%%,*}
a
> echo ${T%,*}
a,b,c

Here’s how you could use multiple delimiters.. This is messy and I think there’s a better way but I havent figured it out yet.

#!/bin/bash

line=’content,100,2′

content=${line%%,*}

delay=${line#*,}

delay=${delay%,*}

instance=${line##*,}

echo $content

echo $delay

echo $instance

Is there a way to get this to work with more than once delimiter present?

hi,
what if file names with more than one whitespace are listed?

Anton,
Love the tutorial, great stuff and very helpful. I do have a question however. Suppose I am wanting to read specific contents within a text file like name, address, phone, etc… and put it into another file to archive. How do I read the file using Bash and make it look for keywords to recognize what I need it to read? (hope that makes sense) =)

I think its a great idea, if i can get hold of the parts that cheaply over hear in Endland, then i think i might have a go. it seems like a really interesting way to create art in public places. i always like playing with new mediums, and this sound like one of the more inventive ideas i’ve heard of recently. you probably won’t get this cos the last update was last year, but thanks anyway. Rxx

Great idea for the shuffle! The “sort” might or should be “sort -n”, at least for consistency. BTW, I compared your shuffle() with a simple perl script using mainly “splice(@array, rand @array, 1)”. The perl shuffles 40k lines in 0.5 seconds whereas your shuffle() takes 8.2 seconds on a 2.4 GHz Xeon. Of course, the difference is of less importance when the number of lines is lower.
