Re: Would it be possible/hard to write a version of 'at' that executes "right away" to get around ssh username=SYSTEM?

And in case anyone is interested, here is a bash function that launches a
command via 'at' at the next minute and returns the number of seconds until
the launch (actually if you are less than 5 seconds before the next minute,
it waits until the minute after so that at has time to setup - you could
probably use a number smaller than 5 seconds of course)
function at_launch ()
local h m s wait command
set -- $(date +"%H %M %S")
h=$((10#$1)) #Note explicitly use base 10 so that 08 and 09 not
interpreted as bad octal
m=$((10#$2 +1)) #Advance minutes by 1
wait=$((60 - $s))
[ $s -gt 55 ] && let "m += 1" "wait += 60" # Make sure >5 seconds left
[ $m -ge 60 ] && let "m %= 60" "h += 1" #Overflow minutes
let "h %= 24"
at $h:$m $(cygpath -w $(which bash.exe)) -c \"$command\" > /dev/null
