fsplit(1) BSD General Commands Manual fsplit(1)
NAME
fsplit - split a multi-routine Fortran file into individual files
SYNOPSIS
fsplit [-e efile] ... [file]
DESCRIPTION
fsplit takes as input either a file or standard input containing Fortran
source code. It attempts to split the input into separate routine files
of the form name.f, where name is the name of the program unit (e.g.
function, subroutine, block data or program). The name for unnamed block
data subprograms has the form blkdtaNNN.f where NNN is three digits and a
file of this name does not already exist. For unnamed main programs the
name has the form mainNNN.f. If there is an error in classifying a pro-
gram unit, or if name.f already exists, the program unit will be put in a
file of the form zzzNNN.f where zzzNNN.f does not already exist.
-e efile 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 files.
DIAGNOSTICS
If names specified via the -e option are not found, a diagnostic is writ-
ten to standard error.
HISTORY
The fsplit command appeared in 4.2BSD.

BUGS
fsplit assumes the subprogram name is on the first noncomment line of the
subprogram unit. Nonstandard 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.
