Re: Preventing "no matches found:"

Thanks to both. I was looking for the ,N, as I've come up with a few methods to "silence" it otherwise, but I felt there was likely a more elegant manner.

You can turn on noglob for a single pattern by adding a (N) flag.  So
you could just do:

rm ~/log/**/*.log(m+7,N)



I knew there was a flag like that but I couldn't find it offhand.



But that doesn't really solve your problem, because if rm has no
arguments, it'll complain.  Now, my personal advice would be to not
care, but if you do care, you could do this:
deadlogs=(~/log/**/*.log(m+7,N))
((#deadlogs)) && rm $deadlogs
I used xargs so rm would never be called without arguments, avoiding this problem. But your solution is a little more flexible, e.g. you could emit a 
message depending on whether any files will be/were removed:

    deadlogs=(~/log/**/*.log(m+7,N))
    if (( $#deadlogs == 0 ))
    then
    echo "No longs removed."
    else
    rm $deadlogs
    echo "$#deadlogs logs removed."
    fi
