comment Is there a way to redirect output to a file without buffering on unix/linux?
@Calmarius: compiling coreutils should be quite easy. Just grab a new version from ftp.gnu.org/gnu/coreutils and give it a go. It's standard ./configure && make fare. You don't even have to install it afterwards, you can just use the stdbuf binary off src/.

comment How network devices affect TTL
@Pacerier: allow me to clarify. With IPv4 a router has to decrement the TTL field by at least 1, but may choose to decrement TTL by more than 1. In IPv6 the "hop limit" should always be decreased by 1 as per RFC 2460.

comment How network devices affect TTL
@Pacerier: I don't know of any difference apart from the name. I'm guessing it was changed to make it clear that the original semantic from IPv4 RFCs (using TTL literally as a time field instead of the more common hop count, at least in some cases) is deprecated.

comment Run an interactive bash subshell with initial commands without returning to the (“super”) shell immediately
@SABBATINILuca: I'm not saying anything like that. This is just a way, and mktemp does solve the temp file issue as @cjc pointed out. Bash could support reading the init commands from stdin, but as far as I can tell it doesn't. Specyfing - as init file and piping them half works, but Bash then exits (probably because it detected the pipeline). The elegant solution, IMHO, is to use exec.
