This can be a bit tricky in portable shell, but maybe this is closer
to what you want:
if [ `/bin/ls /dumps` != '' ]

I'll try that, but IIRC if the dir is empty, ls still returns a linefeed.
brb.
Nope, tried with !='' and !='\n', with almost the same result, the diff being
that now the error message on the console is minus the ending ] now.
./flush.sh: line 173: [20091019011512: command not found
In portable shell, there must be space before and after the '[' and ']'
as well as before and after the comparison operator.
I fail to see why bash is looking for that ls return as a command to be
executed, almost like bash is busted, and its been ages since bash was
updated. This script has worked many times since the last time I saw a bash
update go by.
its enough to make a fellow wish it was beer-thirty and I haven't even
finished my first cup of tea!
