[NTLUG:Discuss] An Oddity (bug) in Redhat 7.1

[Kenneth Loafman]

An interesting bug was found in RH 7.1 shell.  Redirection of both
stdout and stderr can be done with either >& or &>, with the first form
being predominate in use.  Both are semantically equivalent according to
the bash manual.  I've been using >& for years and its embedded in a lot
scripts since it works on every other distro.  Not so for Redhat 7.1.

  *** &> will redirect both while >& redirects nothing ***

I've attached a pair of files.  Put both files in a directory, run the
'testredir' script, and you should see only two lines, and two output
files should be created.  On a Redhat 7.1 system only one of the paths
works to create the log file.  The test for >& seems to ignore that and
the output file name.

Just thought you'd like to know.
