To run Mathematica on the background I use the following procedure. The
aim is to start Mathematica at a specific time, run Mathematica commands
which are stored in a file, store the results in another file, then exit

The procedure has nothing to do with Mathematica itself, but with the
Unix operating system. In other words, the same can be done to any
application. The Unix 'at hhmm' command starts off a process at military
time hhmm. The construct ends with ^D (Control key + D). The construct
'<< eof ... eof' tells the shell that the commands are input for
Mathematica rather than for the shell itself.

A working code is as follows. Suppose that at 4.15 pm we want
Mathematica do run the code in file 'MathRemoteCode.txt', store the
results of the computations (a list) in file 'computedList1645010297'
and finally exit.

'at' command

at 1645
math << eof
Exit[ ]
