generally people make the mistake of assuming an environment where a
cron script would not have so for example, running...

ls assumes the environment of /bin so if you want to bury it in a script
run from cron, you would replace 'ls' with '/bin/ls' if you want it to
run... etc. Always provide absolute paths to scripts that may possibly
be run without an environment. Don't take for granted that whatever you
get for 'echo $PATH' will also be the same for a script.
