I'm trying to use at command in the following,

at 19:32 04/02/2015 < /usr/bin/python /home/myscript.py

But I get the error

syntax error. Last token seen: /
Garbled time

I'd like to run the script directly from shell without having to placing the python command in a .sh script and using at -f python.sh

Two problems;

  • The at date format is funny (not quite Yoda funny but still).

  • You are trying to use file redirection on something which isn't a file.

Try this instead;

at 19:32 Apr 2 <<':'
  /usr/bin/python /home/myscript.py
:

If I am reading the at timespec correctly, the year field is only two digits. It's still dd/mm/yy not American wacky mm/dd/yy.

at 19:32 02/04/15 <<<'/usr/bin/python /home/myscript.py'

Here strings are Bash only; yet another alternative is

echo '/usr/bin/python /home/myscript.py' | at 19:32 02/04/15

Everything right, except the timespec works on the "American wacky mm/dd/yy" :)
Hmm, looks like that is locale-dependent, actually. I was looking at an ancient BSD man page.
Ah, echoing any script/command does'nt seem to work here, does it work on your end? echo "any_command" | at 19:32 02/04/15
Huh? at doesn't care (and indeed cannot know) how the shell connects its standard input before it runs. A pipe is just as fine as a here document or (in Bash) a here string.
