Divide large data files into smaller files

Hello everyone!

I have 2 types of files in the following format:

Code:
1) *.fa

>1234
...some text...
>2345
...some text...
>3456
...some text...
.
.
.
.

2) *.info

>1234
...some numbers...
>2345
...some numbers...
>3456
...some numbers...
.
.
.
.

I need to split these huge files (~300-400Mb), into smaller files (around 30-40Mb each). Also, I don't want to divide the data (i.e. every record starting with '>' should have its corresponding information in one smaller file).

Can someone please suggest a way to do this using unix commands?

Thanks!!!

NAME
getunimap - dump the unicode map for the current console to stdout SYNOPSIS
getunimap [ -s ] [ -C console ] DESCRIPTION
The getunimap program is old and obsolete. It is now part of setfont (1). The getunimap program outputs the unicode map (also called a "Screen Font Map") for the current console to standard output. The -C option may be used with Linux 2.6.1 and later to get the map for a console different from the current one. Its argument is a path- name. The output of getunimap is of the form 0xAA U+1234 # comment where 0xAA is the font character code and U+1234 is a unicode character, that if displayed, will be displayed using glyph 0xAA in the font. Many unicode characters may be mapped to the same glyph. the Hash symbol # is used as a comment delimiter; characters after a hash sign (to the end of the line) are comments. The -s option will sort and merge elements, sorting on font character. Hence, it will produce output of the form: 0x22 U+1234 U+5678 U+3456 0x23 U+0023 etc., listing the multiple unicode characters that map to a font glyph. The output of getunimap is of the form accepted by setfont and psfaddtable SEE ALSO
