[Novices] very simple at commands

[Steve Petersen]

Oh, right, piping.  I reckon I could do that.  (If I remember, and 
remember to enclose the command I want to pipe into "echo".)

Hmn.  How might I (or you!) write a shell script that takes an at-like 
time spec and a command line and does the command at the time?  I 
*think* using that script would be easiest for me to remember later, and 
anyway it would be a good lesson for me in shell scripting.  A script 
'doat' where I could type

	$ doat now + 1 minute echo "Go to the meeting"

That would seem hard to code up.  Maybe easier with a '-c' between them 
(though that would also take remembering).

Also, I had forgotten (or never knew) that standard output of at gets 
mailed.  I don't often use it for echo, as in my example, but is there 
any way to send it to the invoking terminal instead?

Maybe I should just remember ^D.  I used to use it 15 years ago for 
writing email, after all.  But I can't think of another case where I use 
it today.

Thanks again novice-helpers,
Steve
