"Use the source, Luke" <grin>

from the changelog for bash2.05
-------------------------- quote ----------------------------
This document details the changes between this version,
bash-2.05-release, and the previous version, bash-2.05-beta2.

3.  New Features in Bash

a.  The `>&word' redirection now works in POSIX mode as it does by default,
    since POSIX.2 leaves it unspecified.
-------------------------- end quote ------------------------

RH 7.2 host (bash2-05):

bash-2.05$ ./testredir
Test with \&\>
Test with \>\&
==========================
testredir1 started
==========================
testredir1 started
bash-2.05$ cat testredir testredir1
#! /bin/sh
bash-2.05$ ./testredir ; cat testredir testredir1
Test with \&\>
Test with \>\&
==========================
testredir1 started
==========================
testredir1 started
#!/bin/sh

echo "Test with \&\>"

./testredir1 &> testredir1a.log

echo "Test with \>\&"

./testredir1 >& testredir1b.log

echo "=========================="
cat testredir1b.log
echo "=========================="
cat testredir1b.log
#!/bin/sh

echo "testredir1 started"

bash-2.05$

(that is, expected results -- I have made quoting changes on
the echo, and the she-bang to conform to my coding style)

--------------------------------------------

RH 7.1 (bash2.04) -- Expectedly, I do not get the second file
either:


[root at serverc /root]# ./testredir ; cat testredir testredir1
Test with \&\>
Test with \>\&
testredir1 started
==========================
testredir1 started
==========================
cat: testredir1b.log: No such file or directory
#!/bin/sh

echo "Test with \&\>"

./testredir1 &> testredir1a.log

echo "Test with \>\&"

./testredir1 >& testredir1b.log

echo "=========================="
cat testredir1a.log
echo "=========================="
cat testredir1b.log
#!/bin/sh

echo "testredir1 started"

[root at serverc /root]#
