fScan Reference Manual, Chapter 2 (CmdLineOptions): options
The OPTIONS command lets you specify command line options from files or interactively. With no arguments this allows options to be entered via an interactve menu. If NAME is a character string, it is assumed to refer to a file named 'name.fscan'; the contents of that file will then be inserted into the fScan command line. If that file is not found in the current directory it will be looked for in your fScan home directory. Your fScan home directory can be defined via the global environment variable FSCANUSRHOME. If the file is not found there it will be looked for in the system-wide fScan home directory, specified by the global environment variable FSCANHOME. The default for FSCANHOME is: /usr/local/lib/FSCAN
NOTE: The '-options' can be omitted when NAME refers to a '.fscan' file,
provided that NAME is more than 2 characters long. This means you
can use “-name”, instead of “-options name”. For example,
'-recon' is the same as '-options recon'
and '-physiofilter' is the same as '-options physiofilter'
In the command line, the “-options name” or “-name” arguments themselves are replaced by “[-options name]” or “[-name]” and ignored thereafter. This is done so that the command history (which is stored in each output file) reflects the command arguments as specified, as well as the final arguments actually used in processing.
To find the option files currently available, enter “-options” with no arguments.
