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.

     -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 written 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 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] [-p pattern] [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.

     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 n lines in length.

     -p pattern
	     The file is split whenever an input line matches pattern, which is interpreted as an extended regular expression.	The matching line
	     will be the first line of the next output file.  This option is incompatible with the -b and -l options.

     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, the file is split into lexically ordered files named with prefixes in the range of ``x-z'' and with
     suffixes as above.

STANDARDS

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

HISTORY

     A split command appeared in Version 3 AT&T UNIX.

BUGS

     For historical reasons, if you specify name, split can only create 676 separate files.  The default naming convention allows 2028 separate
     files.  The -a option can be used to work around this limitation.

     The maximum line length for matching patterns is 65536.
