so there is no way to use the 'at now +' command options? maybe I can
query the time add thirty seconds then initiate the at command.

while looking at man at again i see
at -f $HOME/future -t201312271220.00
is there a way of generating the date output similar to the format
used in the example
[year][month][day][24 hour][minute].[sec] + 30 sec.

If you're really doing it the way you're saying, you can just do:

at now
sleep 30
../startscripts
ctrld

But you said "I'm trying to use a script that uses the 'at' command to
start scripts.". If you really are using a *script* that uses the 'at'
command, then you will have to insert the "sleep 30" either in the
invoking script or the invoked script. However your example is not a
script, but commands entered at the command line (in a script you can't
have commands after the "at" command and you can't have a ctrld (well
you can do *similar* things, but not those exact things)).

BTW, IIRC "at now", i.e. without '+ ...' can sometimes give problems
because the imaginary time 'now' has already passed when at(1) actually
executes. IIRC, the at(1) manual page has another command which is
essentially a "at now" but without the mentioned problem. IIRC, that
other command is 'batch'.

date +%Y%m%d%H%M.%S
You'll have to figure out how to add 30.

(sleep 30 && ./startscripts &) /dev/null 2>&1

Besides reading "man at" users could use "man batch".

perl -e 'print scalar(localtime(time + 30)), "\n"'
or
perl -e 'use POSIX; print scalar(strftime("%Y%m%d%H%M.%S", localtime(time + 30))), "\n"'
