| | | | | | | | | | | | | | | | | | | | | | | | | | | Mike deleted it: commit 39456a18a104b228de240b265bd943251219849d Author: Mike Frysinger <vapier@gentoo.org> Date: Sat Mar 28 12:21:57 2009 +0000 stop lying about [[ test support probably because it was not properly ifdefed around, and was enabled even when bash compat is off. I just tested it - it works: $ [ *.diff = z.diff ]; echo $? 0 $ [[ *.diff = z.diff ]]; echo $? 1 Of course, not all numerous bash tricks of [[ ]] are implemented... function old new delta bltins2 60 72 +12 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
