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. AUTHOR
Asa Romberger and Jerry Berkman 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. 4.2 Berkeley Distribution April 29, 1985 FSPLIT(1)

NAME
split -- split a file into pieces SYNOPSIS
split -d [-l line_count] [-a suffix_length] [file [prefix]] split -d -b byte_count[K|k|M|m|G|g] [-a suffix_length] [file [prefix]] split -d -n chunk_count [-a suffix_length] [file [prefix]] split -d -p pattern [-a suffix_length] [file [prefix]] DESCRIPTION
The split utility reads the given file and breaks it up into files of 1000 lines each (if no options are specified), leaving the file unchanged. If file is a single dash ('-') or absent, split reads from the standard input. The options are as follows: -a suffix_length Use suffix_length letters to form the suffix of the file name. -b byte_count[K|k|M|m|G|g] Create split files byte_count bytes in length. If k or K is appended to the number, the file is split into byte_count kilobyte pieces. If m or M is appended to the number, the file is split into byte_count megabyte pieces. If g or G is appended to the num- ber, the file is split into byte_count gigabyte pieces. -d Use a numeric suffix instead of a alphabetic suffix. -l line_count Create split files line_count lines in length. -n chunk_count Split file into chunk_count smaller files. -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 prefix argument is not specified, the file is split into lexically ordered files named with the prefix ``x'' and with suffixes as above. ENVIRONMENT
The LANG, LC_ALL, LC_CTYPE and LC_COLLATE environment variables affect the execution of split as described in environ(7). EXIT STATUS
The split utility exits 0 on success, and >0 if an error occurs. SEE ALSO
csplit(1), re_format(7) 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
The maximum line length for matching patterns is 65536. BSD
