[histappend/Bash 5.1.4/Tilix/Debian 11] Duplicate entries in ~/.bash_history

[thebahadir]

After installing ble.sh, all commands I type into the shell are recorded twice in a row in the ~/.bash_history I added export HISTCONTROL=ignoreboth:erasedups in ~/.bashrc but nothing changed.

For example;

sudo apt update
apt list --upgradable 
sudo apt full-upgrade -y
sudo apt autoremove 
sudo apt update
apt list --upgradable 
sudo apt full-upgrade -y
sudo apt autoremove 

Thank you in advance for your help.

[akinomyoga]

Which version of ble.sh do you use? If you use 0.3, could you use 0.4. I don't remember the command-history issues (and their situations) caused with v0.3, but there are many improvements in 0.4, and also I'm not planning to fix these minor issues in v0.3.

If you are already using ble-0.4 (in master), it doesn't happen in my environment, and also I haven't recognized the problem so far except in the case where one calls builtin history ... in the Bash configuration. If you don't have builtin history ... in your configuration, depending on the actual cause, maybe I can add some workarounds in ble.sh.

• Q1: Which version of ble.sh and Bash do you use exactly? Could you paste the result of the following command in a ble.sh session?

$ ble/widget/display-shell-version

• Q2: Do you call history ... in your bash configuration? If so, could you provide us with your configuration?

[thebahadir]

Ble.sh version 0.4 and bash version 5.1.4

here is the output of ble/widget/display-shell-version;

GNU bash, version 5.1.4(1)-release (x86_64-pc-linux-gnu) [Debian GNU/Linux 11 (bullseye)]

[akinomyoga]

Thank you! I tried your bashrc with Bash-5.1.0 and Bash-5.1.16, but it doesn't seem to reproduce in both versions of Bash.

• Q3: Could you check if the problem reproduces with the following simple bashrc?

$ cd
$ mv .bashrc .bashrc.backup20230210 # <-- please save your original .bashrc before testing

$ cat .bashrc      # ... please edit .bashrc to make it have the following contents
export HISTCONTROL=ignoreboth:erasedups
shopt -s histappend
HISTSIZE=1000
HISTFILESIZE=2000
source ~/.local/share/blesh/ble.sh --norc

$ bash   # <-- start a new Bash session
$ echo test2023 # <-- run some command
$ echo test2024 # <-- run some command
$ exit
$ tail .bash_history

[thebahadir]

I did what you said and the problem persists despite this simple ~/.bashrc configuration.

[akinomyoga]

Thank you for testing. Hmm, so maybe some other differences between your environment and mine are causing the issue.

• Q4: Could you check if the problem persists with the following bashrc?

HISTCONTROL=ignoreboth:erasedups
HISTSIZE=1000
HISTFILESIZE=2000
source ~/.local/share/blesh/ble.sh --norc

• Q5: Could you check if the problem persists with the following bashrc?

HISTCONTROL=
shopt -s histappend
HISTSIZE=1000
HISTFILESIZE=2000
source ~/.local/share/blesh/ble.sh --norc

[thebahadir]

This configuration fixed the problem. I'll try to edit bashrc with that in mind. Thank you very much for your interest.

HISTCONTROL=ignoreboth:erasedups
HISTSIZE=1000
HISTFILESIZE=2000
source ~/.local/share/blesh/ble.sh --norc

[akinomyoga]

Thank you for the information! So this means that histappend is related. However, the problem still doesn't seem to reproduce in my environment with shopt -s histappend. Hmm, ...

[thebahadir]

Maybe the problem is with the OS. I am using Debian 11 (Bullseye) on my physical machine. I also have a Debian 11 installed on my virtual machine for testing purposes. I tested it on both physical and virtual machine and both had the same issue.

[akinomyoga]

Thank you. I had an instance of Deabin 10 in a virtual machine, so I tried it there, but the problem still doesn't seem to reproduce. Maybe I need to set up Deabin 11 in a new virtual machine.

But before that, I would like to check about the possibility that the prompt setting might be related.

• Q6: What is your prompt settings? Could you provide the result of the following command?

$ echo "$PS1" | cat -v
$ echo "${PS1@P}" | cat -v

[thebahadir]

"$ echo "$PS1" | cat -v" output; \[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$

"$ echo "${PS1@P}" | cat -v" output; ^A^[]0;bahadir@debian: ~^G^B^A^[[01;32m^Bbahadir@debian^A^[[00m^B:^A^[[01;34m^B~^A^[[00m^B$

[akinomyoga]

Hmm, thanks!

• Q7: What is the result of the following command?

$ echo "$PROMPT_COMMAND"

[thebahadir]

$ echo "$PROMPT_COMMAND" output;

__vte_prompt_command

[akinomyoga]

Ah, I suspect this.

• Q8: What is your terminal?
• Q9: What is the result of the following command?

$ type __vte_prompt_command

[thebahadir]

I am using Tilix as terminal.

type __vte_prompt_command output;

__vte_prompt_command is a function
__vte_prompt_command()
{
     local pwd='~';
     [ "$PWD" != "$HOME" ] && pwd=${PWD/#$HOME\//\~\/};
     pwd="${pwd//[[:cntrl:]]}";
     printf "\033]0;%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${pwd}";
     __vte_osc7
}

[akinomyoga]

Thanks! Hmm, it doesn't seem to be related as far as I look at the result.

I think I need to later set up Debian 11. If it still doesn't reproduce in my Debian 11, I'll ask further questions later. Thank you!

[thebahadir]

Thank you for your interest and support.

[akinomyoga]

I now set up Debian 11 and tried ble.sh in Bash 5.1.4 / Tilix, but the problem doesn't reproduce. I don't even get the value PROMPT_COMMAND=__vte_prompt_command in https://github.com/akinomyoga/ble.sh/issues/277#issuecomment-1426067197. I suspect you have other Bash configurations.

• Q10: Could you try this:

With the following ~/.bashrc,

# bashrc
HISTCONTROL=ignoreboth:erasedups
HISTSIZE=1000
HISTFILESIZE=2000
shopt -s histappend
source ~/.local/share/blesh/ble.sh --norc

Could you see if the problem persists within a child Bash session started by

$ INPUTRC=/dev/null PS1='\$ ' bash --noprofile
$ echo 2025 # <-- some commands
$ echo 2026 # <-- some commands
$ exit # <-- exit the session
$ tail ~/.bash_history # <-- check if there are duplicate entries of the executed commands

[thebahadir]

I did what you said and saw that the problem did not persist. How can I have a different bash configuration on both my physical machine and virtual machine without my knowledge?

[akinomyoga]

Thank you! Now I guess we can identify the condition to reproduce it soon.

How can I have a different bash configuration on both my physical machine and virtual machine without my knowledge?

Other Bash configurations may be located in /etc/profile, /etc/bash.bashrc, /etc/profile.d, etc. depending on the Linux distributions. One possibility is that a particular package you install on both the physical machine and the virtual machine puts some non-trivial Bash configuration in /etc/profile.d.

• Q11: As a next step, could you try the following with the same simple bashrc as https://github.com/akinomyoga/ble.sh/issues/277#issuecomment-1426558893?

$ PS1='\$ ' PS4='+$BASH_SOURCE:$LINENO: ' bash -x # start a new child session here

<--- Could you provide us with the output here?

$ echo 2027 # <-- some commands
$ echo 2028 # <-- some commands
$ exit # <-- exit the session
$ tail ~/.bash_history

<-- Could you again check if there are duplicate entries of the executed commands?

There is a ~/.profile file.

Hmm, ... Now I doubt the answer to Q3. Could you try Q3 in https://github.com/akinomyoga/ble.sh/issues/277#issuecomment-1425851115 again? Just to make sure, you need to start the Bash session as a child session as presented in https://github.com/akinomyoga/ble.sh/issues/277#issuecomment-1425851115 but not as a new terminal window.

Q12: Do you have ~/.bash_profile or ~/.profile? If any, what are the contents of these files?

There is a ~/.profile file.

~/.profile file content;

Thanks, this seems to be the same as mine in my Debian 11 instance.

[akinomyoga]

OK, I was checking the configuration of Tilix. It seems there is an option [Profiles] - [Current profile] - [Command] - [Run command as a login shell]. I guess you turned on it. Now I could reproduce your PROMPT_COMMAND=__vte_prompt_command.

However, the problem still doesn't seem to reproduce. Anyway, I currently suspect Bash configurations that are installed in /etc/profile.d in your system.

Hmm, OK.

Thank you for your help so far. If you have noticed something later, please feel free to come here again. Thank you very much!

Edit: For my note:

• I see apps-bin-path.sh in the result of ls -l /etc/profile.d in https://github.com/akinomyoga/ble.sh/issues/277#issuecomment-1426704574, which I didn't have in my Debian 11 instance. I searched for it and found that it is a part of the snapd package. I installed the package using sudo apt install snapd and tried again if the problem reproduces with the simple .bashrc of Q5 or Q10. However, I still cannot reproduce the problem.
• Another difference in /etc/profile.d is that I only have vte-2.91.sh but don't have vte.sh. I guess vte.sh is a remnant of an old version of the corresponding package. In fact, vte.sh seems to be loaded after vte-2.91.sh in the original reporter's system. It seems an old version of the VTE integration code contained history 1..., but I don't think it would affect the contents of .bash_history. Also, I don't observe the lines in https://github.com/akinomyoga/ble.sh/issues/277#issuecomment-1426080965.
• Do some environment variables cause this issue?
• I noticed that /tmp is not tmpfs in Debian, but there is /var/run/... on the other hand. ble.sh correctly selects /var/run/$UID/blesh in my case. Even if /tmp is selected and is not tmpfs, I don't think the problem would be caused by that.
