I have configured my own .bash_myhistory
export HISTFILESIZE=
export HISTSIZE=
export HISTTIMEFORMAT="[%F %T] "
export HISTFILE=~/.bash_myhistory
PROMPT_COMMAND="history -a; history -r; $PROMPT_COMMAND"
When I run history it shows me many repetitive output:
$ history | grep 'git rebase'
75 [2018-05-23 16:39:39] git rebase -p dev_hypermouse
168 [2018-05-23 19:27:39] man git rebase

5008 [2018-05-28 16:17:46] git rebase --onto dash_v2 xxx 296-ToS-component
...
But $ cat ~/.bash_myhistory | grep 'git rebase' does not:
man git rebase
git rebase master
git rebase master
git rebase xxx
git rebase dash_v2
man git rebase
man git rebase
git rebase xxx dash_v2
git rebase --onto dash_v2 xxx 296-ToS-component
man git rebase
man git rebase
history | grep git rebase
history | grep 'git rebase'
How to fix repetitive output from history?
UPD
with export HISTCONTROL=ignoreboth:erasedups history looks much better but duplicates still exists:
$ history | grep 'git rebase'

UPD
Even after adding export HISTCONTROL=ignoreboth:erasedups history looks like:
25988 [2018-07-26 17:13:19] gd 1
25989 [2018-07-26 15:45:47] mc
25990 [2018-07-26 13:57:46] mc
25991 [2018-07-26 09:23:28] mc
Also I notice that some commands disappear from history =(
export HISTCONTROL=ignoreboth:erasedups
From bash man page:
HISTCONTROL
A colon-separated list of values controlling how commands are saved on the history list. If the list of values includes ignorespace, lines which begin with a space character are not saved in the history list. A value of ignoredups causes lines matching the previous history entry to not be saved. A value of ignoreboth is shorthand for ignorespace and ignoredups. A value of erasedups causes all previous lines matching the current line to be removed from the history list before that line is saved. Any value not in the above list is ignored. If HISTCONTROL is unset, or does not include a valid value, all lines read by the shell parser are saved on the history list, subject to the value of HISTIGNORE. The second and subsequent lines of a multi-line compound command are not tested, and are added to the history regardless of the value of HISTCONTROL.
