All those commands are to be run from the command line, not inside an nwchem input file python block.

fft1d is a MatLab or octave script and only needs the file name as an argument, i.e.,
 octave -q fft1d.m x.dat > xw.dat
...unless you have explicitly set your desktop environment to execute .m files using octave.
