Hi RudiC,
The standard split utility creates output filenames with sequence "numbers" added to the end of a given output filename prefix where the "numbers" aren't numeric; they are names like fasta.aa, fasta.ab, fasta.ac, ...
Like you said, awk would work well for this.
Hi laura,
To get the requested output, one could use something like:
but that would produce names with varying output lengths that would be inconvenient to process if you wanted to handle them in the same order that they originally appeared in the file named out1. If you do later want to process them in that order, you would probably be happier with something more like:
which would produce all 34900 output files with names that start with 5 decimal digits (with leading zeros on the first 9999 files so normal listings of the produced files are in the order you probably want.
If you intend to try this on a Solaris/SunOS operating system, change awk in both of the above suggestions to /usr/xpg4/bin/awk or nawk.
As RudiC said, next time you need help, plan to tell us what operating system as well as what shell you're using and show us what you have tried to solve the problem on your own. We want to help you learn how to do stuff like this on your own; not to act as your unpaid programming staff.

BASHBUG(1) General Commands Manual BASHBUG(1)NAME
bashbug - report a bug in bash
SYNOPSIS
bashbug [--version] [--help] [email-address]
DESCRIPTION
bashbug is a shell script to help the user compose and mail bug reports concerning bash in a standard format. bashbug invokes the editor
specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill in the appropriate
fields and exit the editor. bashbug then mails the completed report to bug-bash@gnu.org, or email-address. If the report cannot be
mailed, it is saved in the file dead.bashbug in the invoking user's home directory.
The bug report format outline consists of several sections. The first section provides information about the machine, operating system,
the bash version, and the compilation environment. The second section should be filled in with a description of the bug. The third sec-
tion should be a description of how to reproduce the bug. The optional fourth section is for a proposed fix. Fixes are encouraged.
ENVIRONMENT
bashbug will utilize the following environment variables if they exist:
EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs.
HOME Directory in which the failed bug report is saved if the mail fails.
TMPDIR Directory in which to create temporary files and directories.
