Why don't you try something like

Code:

*/2 * * * * /usr/bin/ls /home > /home/test/ls.txt

Actually, does /usr/bin/ls exist or is it an inate system command?

Code:

*/2 * * * * ls /home > /home/ls.txt

works for me, whereas the version I posted previously produces a zero length file

It may be because the cron process didn't have permission to create the file (e.g. /home/test/ doesn't exist, or has the wrong permissions). Only the logs will tell you for sure. Check /var/log/cron and read your email for any messages from cron.

for non-working cron job always watch the log file.
The default log file for cron job is /var/log/cron
