randomly renaming files
I have a directory of files that look like filename 001.ext, filename 002.ext, etc. I'd like to rename the files with unique random numbered names, so that the original filenames are stripped and the files are given a new, random number name. I'm not super new to UNIX, but I don't often use it for this kind of scripting. I'm going to keep browsing the forums for usable code, but any suggestions you may have quickly would certainly be very appreciated. Thanks always.

VSTP(1) BrlNet User's Manual VSTP(1)
NAME
vstpg, vstpp - VisioBraille file transferring
SYNOPSIS
vstpg [-ifbnd] [-s socketport] [-k keyname] [-o configname] file ...
DESCRIPTION
vstpg (resp. vstpp) gets (resp. puts) files from (resp. onto) a VisioBraille terminal.
For communicating with the terminal, you must launch brltty with the BrlNet driver, and telling BrlNet to use the VisioBraille driver.
Before putting on the terminal, file names are truncated to 8 characters without any extension.
Before getting from terminal, leading path and trailing extensions are removed, but put back for local filename.
COMMAND-LINE OPTIONS
-i ask for confirmation of transfer, for each file (on the terminal)
-f don't ask for such a confirmation (default)
-b if they exists, recursively rename the old files with an added .x suffix, just like logrotate does
-n do not keep such backup file (default)
-s socketport
use socketport as the port number instead of default for connecting to BrlNet
-k filename
use filename as key path instead of default for reading BrlNet's authentication key
-d use current directory rather than the download directory (see vbs_dir below)
-o filename
also read filename as config file
CONFIG FILE
vstpg and vstpp read a configuration file $HOME/.vstprc which contains keywords or equalities, one per line (what follows a # is ignored).
You can ask them to also read any other file thanks to the -o option.
Here are keywords:
backup make -b option the default
nobackup
make -f option the default
and equalities:
keyname = filename
use this file instead of default, to find BrlNet's authentication key
socketport = port
use this port number, instead of default, to connect to BrlNet
vbs_ext = .ext
use .ext as an extension for downloaded files (.vis by default) this is overriden on command line if an extension is provided in the
file name
vbs_dir = path
use path instead of current directory for putting files, except when using the -d option, or if the filename begins with '.'
RETURNED VALUE
1 syntax error on command line
2 connection with BrlNet error
3 Unix file error
4 Protocol error
16 interrupted by user
SHELL EXPANSIONS
Beware of special chars: * and . are often expanded by your shell, hence vstpp * will probably do what you want, putting every file exist-
ing in the current directory onto the terminal, but vstpg * may not do what you want: it will only get every file which already exist in
the current directory, skipping those you just created on your terminal ! If you want to get every file which exist in the terminal, you
should use vstpg '*' or something similar (please read your shell manual).
The same warning applies to other special chars, such as $, ~, &,... which should be protected by surrounding arguments by quotes (') or by
using single backslashes () just before them (please read your shell manual).
BUGS
The one we could find has been corrected :)
