I would like to both share history across terminals and keep track of elapsed time for history commands. The intuitive way seems to be to use both EXTENDED_HISTORY
and SHARE_HISTORY
, but this sets all elapsed timestamps to 0 after restarting the shell. Is this the correct way to do it? Is it even possible?
Scenario 1: EXTENDED_HISTORY
and SHARE_HISTORY
$ history -Dn | sed 's|\\n|\n |g'
0:00 cat << EOF > ~/.zshrc
HISTFILE=~/.zhistory-test
HISTSIZE=100
SAVEHIST=100
setopt EXTENDED_HISTORY
setopt SHARE_HISTORY # the only change compared to below
EOF
0:00 exec zsh
0:00
sleep 1
0:00 exec zsh
Scenario 2: only EXTENDED_HISTORY
$ history -Dn | sed 's|\\n|\n |g'
0:00 cat << EOF > ~/.zshrc
HISTFILE=~/.zhistory-test
HISTSIZE=100
SAVEHIST=100
setopt EXTENDED_HISTORY
EOF
0:00 exec zsh
0:01
sleep 1
0:00 exec zsh
Scenario 3: INC_APPEND_HISTORY
and SHARE_HISTORY
Same as scenario 1, but replacing SHARE_HISTORY
with INC_APPEND_HISTORY
seems to have the same effect.
