Splitting large files
Hi Unix gurus,
We have a masterfile which is to be split into smallerfiles with names as
masterfile00,masterfile01,masterfile03...etal
I was able to split the file using the "Split" cmd
but as masterfileaa,masterfileab..
Is it posiible to change the default suffix?
or is there any other cmd which does the needful
or do we need to rename the smallerfiles
thanking you in anticipation

SPLIT(1) BSD General Commands Manual SPLIT(1)
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.
