Other people might run into this, too. The ps command above says error: process ID list syntax error with procps-ng version 3.3.9 on Ubuntu.

comment Linux log file structure change, abnormal (?) sed behaviour
od is from coreutils. xxd comes from vim-common. Either way, what makes you think a tcp dump can't include space characters? Think telnet or an http stream, for example.

comment Linux log file structure change, abnormal (?) sed behaviour

comment Linux log file structure change, abnormal (?) sed behaviour
sed 's/.* //' won't do what you expect if there are literal spaces in the ASCII dump section. It works for the OP's posted corpus, but it's not reliable unless you know the data will never contains spaces.
