Well, then there's the case with the non-existing file and the other case with an empty file. What about this: f=/tmp/ff && >>$f && [ "$(tail -c1 $f)" ] && echo >>$f || :;stat $f >>$f # like `touch', but no fork (makes sure the file # exists) so `tail' will not fail tail -c1 $f # on an empty file will return "" (as if there was a # a <newline> there ;stat $f # is there just to show what's going on Cheers, -- Cristian _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
