This method is not documented here. Then press Enter. Running SPSS as a background process Running SPSS in the background allows you to work on other things at your terminal while SPSS is running. You should redirect the output to prevent it being displayed on your terminal. The output is redirected to 'test.lst'.
Input is read from the command file 'command.sps' in directory 'itest'.
If the data is in a separate file, then the specification of data files is done within the DATA LIST command. Upper and lower case may be used interchangably in SPSS commands, but case is significant in the string designating the file name. In this case it is necessary to specify more transformation space. It can be increased by using the -s option. This means that the combined size of the output file being produced and the temporary workfile used by SPSS exceed the filespace left.
