Patch Level: 0
Release Status: release


Description:

The conditional expression [ -t -a <anything true> ], e.g. [ -t -a -n
"blabla" ],
should be true when run on a terminal.

This could have to do with the following mentioned in CHANGES:
        Changes between bash-2.05-beta2 and bash-2.05-beta1
        1. Changes to Bash
        o. Fixed a bug in `test' that caused it to occasionally return
incorrect
           results when non-numeric arguments were supplied to `-t'.

Or did I just get it wrong, and -t without arguments should never have
worked ?


Repeat-By:

Type this statement from a terminal:

if [ -t -a -n "blabla" ]; then
        echo 'terminal recognized'
else
        echo 'terminal NOT recognized'
fi
