It's controlled by the HISTCONTROL variable in bash. If it contains 'ignorespace' (or 'ignoreboth' to ignore duplicates as well). Check the man page for more details.

  Anyone know why this incredible hack was introduced in hr first place? In my entire career this "feature" had only caused annoyance after copy-pasting a command. Why not have a shell command called 'nohist' to wrap a command line?

You can control this with the HISTCONTROL and HISTIGNORE environment variables: http://askubuntu.com/questions/15926/how-to-avoid-duplicate-entries-in-bash-history http://askubuntu.com/questions/15926/how-to-avoid-duplicate-...

Much to my dismay this is not true. By default debian is configured to `ignoreboth` ie dupes and spaces. Like you I also change the debian default for HISTCONTROL. Lines 11-13 of /etc/skel/.bashrc:[^1] # don't put duplicate lines or lines starting with space in the history. # See bash(1) for more options HISTCONTROL=ignoreboth [^1]: https://bazaar.launchpad.net/~doko/+junk/pkg-bash-debian/view/head:/skel.bashrc#L11 https://bazaar.launchpad.net/~doko/+junk/pkg-bash-debian/vie...
