BTW, when I disable mcstransd, I do get all "."s [root@rawhide ~]# while :;do mkdir d -Z xxx 2>/dev/null&&{t=X;rmdir d;}||t=.;printf $t;done bash: syntax error near unexpected token `}' What am I missing? bash requires extra spaces near braces (I use zsh, which doesn't). This works even with bash: while :;do mkdir d -Z xxx 2>/dev/null&&{ t=X;rmdir d; }||t=.;printf $t;done Fixed in mcstrans-0.2.8-1.fc9 |
