I distrust backquotes, and so use "$()" instead :P Hello, nice linux related posts going on here :)

I’ve always put inverted commas around the list part and the variable, like so:

#!/bin/bash

for I in “$( ls -rt *.sh )”
do
echo “$I”
done

[user@server ~]$ for I in “$( ls -rt *.txt )” ; do echo “$I”; done
fileone.txt
filetwo.txt
file three.txt

I wasn’t aware of the file globbing properties of “for”; thanks for that :)

Take ‘er easy,

MrKane

ps. I distrust backquotes, and so use “$()” instead :P

Caused me a lot of heartburn! Happy Globbing! I uncovered the differences between ‘for’ and the ‘while-read-do’ loop while writing a script some time ago. Caused me a lot of heartburn!
