Hi Tinker, Very obvious: if you don't want the 'ignorespace' effect for lines with leading spaces, remove these in the commands to record them in history. > Meaning using space prefix can make things not register in the shell > history, that you thought would.

Exactly, see previous comment & read carefully the manual page section: https://man.openbsd.org/ksh#HISTCONTROL I use these bindings and history control options in the $HOME/.profile: bind -m '^L'=^U\ clear'^J^Y' bind -m '^[^L'=^U\ reset\;clear'^J^Y' export HISTCONTROL=ignoredups:ignorespace They work as expected. You don't just paste commands in the terminal.. First, carefully inspect them in a text editor for safety & correctness or make scripts from them. You will save yourself nasty paste mishaps.
