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 program 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.

       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 written to standard error.

BUGS

       Fsplit assumes the subprogram name is on the first noncomment line of the subprogram unit.  Nonstandard source formats may confuse fsplit.

       It is hard to use -e for unnamed main programs and block data subprograms since you must predict the created file name.

NAME

     split -- split a file into pieces

SYNOPSIS

     split [-a suffix_length] [-b byte_count[k|m] | -l line_count -n chunk_count] [file [name]]

DESCRIPTION

     The split utility reads the given file and breaks it up into files of 1000 lines each.  If file is a single dash or absent, split reads from
     the standard input.  file itself is not altered.

     The options are as follows:

     -a      Use suffix_length letters to form the suffix of the file name.

     -b      Create smaller files byte_count bytes in length.  If 'k' is appended to the number, the file is split into byte_count kilobyte
	     pieces.  If 'm' is appended to the number, the file is split into byte_count megabyte pieces.

     -l      Create smaller files line_count lines in length.

     -n      Split file into chunk_count smaller files.

     If additional arguments are specified, the first is used as the name of the input file which is to be split.  If a second additional argument
     is specified, it is used as a prefix for the names of the files into which the file is split.  In this case, each file into which the file is
     split is named by the prefix followed by a lexically ordered suffix using suffix_length characters in the range ``a-z''.  If -a is not speci-
     fied, two letters are used as the suffix.

     If the name argument is not specified, 'x' is used.

STANDARDS

     The split utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     A split command appeared in Version 6 AT&T UNIX.

     The -a option was introduced in NetBSD 2.0.  Before that, if name was not specified, split would vary the first letter of the filename to
     increase the number of possible output files.  The -a option makes this unnecessary.
