fsplit - split a multi-routine Fortran file into individual
fsplit [-e efile [...]] [file]
fsplit takes as input either a file or standard input containing Fortran
source code. It attempts to split the input into separate
of the form name.f, where name is the name of the program
function, subroutine, block data or program).
The name for unnamed block data subprograms has the form
where NNN is three digits and a file of this name does not
For unnamed main programs the name has the form mainNNN.f.
If there is
an error in classifying a program unit, or if name.f already
program unit will be put in a file of the form zzzNNN.f,
does not already exist.
The options are as follows:
Normally each subprogram unit is split into a separate file.
When the -e option is used, only the specified subprogram units
are split into separate files. e.g.,
$ fsplit -e readit -e doit prog.f
will split ``readit'' and ``doit'' into separate
If names specified via the -e option are not found, a diagnostic is written
to standard error.
The fsplit command appeared in 4.2BSD.
Asa Romberger and Jerry Berkman
fsplit assumes the subprogram name is on the first noncomment line of the
subprogram unit. Non-standard source formats may confuse
It is hard to use -e for unnamed main programs and block data subprograms
since you must predict the created file name.
