FSPLIT(1) BSD General Commands Manual FSPLIT(1)NAME
fsplit -- split a multi-routine Fortran file into individual files
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 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.
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. 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.

SPLIT(1) BSD General Commands Manual SPLIT(1)NAME
split -- split a file into pieces
split [-a suffix_length] [-b byte_count[k|m]] [-l line_count] [-p pattern] [file [name]]
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.
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.
SEE ALSO csplit(1), re_format(7)STANDARDS
The split utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
A split command appeared in Version 3 AT&T UNIX.
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.

im new to this forum..excuse me if anythng wrong.
I have a file containing 600 MB data in that. when i do parse the data in perl program im getting out of memory error.

can any one tell me what is the code... (1 Reply)
I have a set of input data that I split into batches using the following command:
split -l 4000000 MyInput.in Split_a
Once I get the split files, I run a certain command on the split files that spews an output. So far I have been doing it without a for loop. How can I translate the... (2 Replies)
i need a little help from you :) ... i need to split a file into separate files depending on two conditions using scripting. The file has no delimiters. The conditions are col 17 = "P" and col 81 = "*", this will go to one output file; col 17 = "R" and col 81 = " ". Here is an example.

I have a file which I want to split into several files based on a condition. This files has several records. I want one record per file. Each record ends with a //. So, I want to separate files based on this condition. I want split files to be named with the name across the field ID (for... (2 Replies)
