Answer by Bruce Ediger for While/Read/Do/Done Loop Cutting Out Halfway Through Text File

You probably should redirect stderr of time /home/admin/all.sh into the log file or some other file. My guess is that you're missing the error message. crond typically emails any stdout or stderr output to the owner of the cron job. I can't tell from your info what user ID that is: might be root. Check the email on that machine for emails from crond to see what that says.
