Here is probably the problem - I expect so.
But - maybe I don't understand what you say - no, I'm not ignoring the
output from top. I suppose you can run this in Smile (or any
equivalent if you don't have Smile):
do shell script "top -tl 2 -o cpu -p '$aaaaaa $cccc ^bbbbbbbbbbbbbbbb'"
this returns a meaningful result OMM...

Hi Axel, thanks for tactfully giving me an occasion to make myself

My script runs on idle. It does:
1. do shell script "top"
2. do shell script "ifconfig"
3. do shell script "mkdir"
Usually it works all right. Sometimes, what I observe is:
The top tool doesn't normally terminate until the user enters
CONTROL C.
I thought AppleScript would wait forever for the termination but
perhaps it is timing out after an interval that isn't uniform. You
are ignoring the output from top. Isn't that what you're looking
for? You say it runs all right sometimes. How do you observe the
output from top?
Does top have an option to run just once? The info in man top seems
to insist on an interactive display on a TTY.
