Bug Report with Git Bash

Bug Report with Git Bash

[sang.tts.designer]

Dear Git community,
I have observed a bug related to git bash at my end. Please the following
description.
Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)
Please note that 'ls' command just an example, it's happening with any
command.
This is a relatively simple bug. when we double-type a command, like 'ls'.
However, in the Ubuntu environment, the command only occurs once when we
press the top arrow to use the prior command.
It is identical when using git bash.
Repeat these steps:
Type "ls: in git bash.
2. Type "ls" once more.
3. To return to the previous command, use the top arrow.
As you can see, the number of times we type the can command 'ls' does not
matter; it only needs to occur once.
Please be aware that the command "ls" is only an example; this can happen
with any command.

What did you expect to happen? (Expected behavior)
It's only need to appear once time and remove duplicated for more
convenience.

What happened instead? (Actual behavior)
It's depending on how many times we type that command.

What's different between what you expected and what actually happened?
As described above.
Anything else you want to add:

Please review the rest of the bug report below.
You can delete any lines you don't wish to share.

Dear Martin,
What a very quick response!
I just tried your recommendation, and it works.
There is no word that can explain my appreciation, to be honest!
Thanks a million.

This depends on how your shell is configured.

Look into HISTCONTROL and ignoredups.

You might want something like

  export HISTCONTROL=ignoredups

in ~/.bashrc.

Hi,

FWIW the reason why you see it in your Ubuntu setup is most likely rooted
in the `/etc/skel/.bashrc` file that contains this:

	# don't put duplicate lines or lines starting with space in the history.
	# See bash(1) for more options
	HISTCONTROL=ignoreboth

Ciao,
Johannes
