I don't have any updates on Tumbleweed (zypper ref; zypper dup) and am on Tumbleweed 20240512. My bash history is intact. Detlev 15 May 2024 10:45:10 Axel Braun :

Nope. I'd suggest to look at $HISTFILESIZE and/or $HISTSIZE. Setting HISTCONTROL to "ignoredups:erasedups" helps to slow down the growth rate.

Your history command store in RAM until you regularly terminate your terminal. Then list of your command write into the .bash_history.

This is true and works as expected - see HISTSIZE and HISTFILESIZE in "man bash". I have set them to 4000000 after having lost my history... @Axel: how much space is free/used in your home directory? Cheers. l8er manfred

Again, put the following into your ~/.bashrc and forget about such issues for a long time: HISTCONTROL=ignoredups:erasedups HISTFILESIZE=4000000 HISTSIZE=4000000 The "ignoredups:erasedups" ensures that identical commands are only saved once - you would have to use more than 4000000 different commands, before the file gets truncated again. HTH, cheers. l8er manfred

I understand that the history file has a maximum size, but reaching it should just limit the size, not set it to zero. cer@Telcontar:~> echo $HISTFILESIZE 1000 cer@Telcontar:~> cer@Telcontar:~> l .bash_history* -rw------- 1 cer users 33941 May 16 12:38 .bash_history -rw------- 1 cer users 24239 Feb 10 2023 .bash_history.20230211 -rw------- 1 cer users 33941 May 16 12:42 .bash_history.20240516 -rw------- 1 cer users 3372 Jan 4 2011 .bash_history.backup -rw------- 1 cer users 1538 Feb 21 2008 .bash_history.backup2 cer@Telcontar:~>

I've seen this bug a couple of times, very infrequently. This could happen if the shell doesn't exit cleanly (a crash), see BASH's maintainer reply here: https://lists.gnu.org/archive/html/bug-bash/2013-07/msg00096.html I am not sure of the current behaviour in BASH, but I assume the same file writing race condition still exits somehow, very infrequent, but still there. To get around that, I do a regular backup of $HOME, which includes ~/.bash_history (and/or a git repo init'ed in ~/, with .bash_history committed to the repo every now and then).
