Problem with extglob patterns used in HISTIGNORE

I have to use sligthly different patterns to work around the issue: export HISTIGNORE="@(?|??|???|)*( |$'\t'):*( |$'\t')" Repeat-By: export HISTIGNORE='@(?|??|???|)*([[:space:]]):*([[:space:]])'

It is aliases like l, ll, .., - or simple commands like vi that I don't want to appear in my history. the [[:space:]] is for cases where I typed v and it expanded to vim
