What is .history file?

[unique name]

In my user home dir, there are numerous .history. files and new ones are popping up. Is this normal?

Login shells like csh and tcsh use these files to store commands that you entered, so you can reuse 'em. Yes, is normal.

Probably not.

I'm not sure what causes the dregs but as far as I know, there should be just one ~/.history file (no dregs). See for example <https://forums.FreeBSD.org/threads/81237/post-523049>

I recently removed some dregs from my home directory.

root@mowa219-gjp4-8570p-freebsd:~ # ls -hl /usr/home/grahamperrin/.histor*
-rw-------  1 grahamperrin  grahamperrin    67K Aug 22 04:37 /usr/home/grahamperrin/.history
root@mowa219-gjp4-8570p-freebsd:~ # ls -hl /usr/home/bbsadmin/.histor*
ls: No match.

I am seeing the same thing. Numerous history files with a number attached.
Example from users home directory:
.history.879329
.history.884368
.history.884856
.history.895317
.history.906169
.history.934475
.history.93622
.history.939921
.history.948512
.history.948584
.history.972109
.history.975053
.history.975309
.history.998851
.history.998894

What I have found is that when I open an Xfce4 Terminal window the history for that goes into a new file.
As seen above.

It is a new mis-behavior for a while now. I don't know if there is a setting or sysctl to funnel them to one history file.
That would be nice... It used to work that way.

There is a way to lose history by logging into the same user twice.
File locking probably blocking one terminals history saves.

I increase users tcsh shell config file to 10000 to keep alot. I find history a great way to write scripts.

set history = 10000
set savehist = (10000 merge)

I have often thought of a .history 'server' so that all my local network .history is collected in central reserve.

… I'm not sure what causes the dregs …

I wondered whether they're left following an ungraceful interruption to something.

I killed Konsole whilst two or three tabs were open, no dregs were found.

… when I open an Xfce4 Terminal window the history for that goes into a new file. …

I get no more than one file when I open an Xfce4 Terminal window.

I have found the opposite. When I had a crashing machine that was shutting down the .history file got wiped out.

My dregs are caused by the xfce4 terminal app. For absolute sure.
I will look at the .config files and investigate.

When I switched to FreeBSD 12 the xfce4 terminal was broke. I had to learn xterm.
A subsequent update fixed the terminal for me.
It was around then that these dregs started occuring. I have 169 dreg .history files right now. How do you merge them?

 

[Phishfry]

Nothing related in /.config/xfce/terminal/rcterminal

But what I noticed is that Xfce terminal is expecting bash_history so maybe that is what I am getting.
Separate history for each bash shell, when using tcsh as default user shell.

how does Terminal 4.4.3 handle history saving? / General discussion / Xfce Forums

when there are 2 or more terminals running, history command outputs differ, so each instance of terminal
seemingly has its own storage

 

[Phishfry]

Well for me it was related to xfce/terminal. The dregs are gone.
/.config/xfce/terminal/rcterminal
CommandLoginShell=TRUE

Also found in the Xfce Terminal Menu >>Edit>>Prefrences>> Check "Run Command As Login Shell"

 

[Cath O'Deray]

Thanks, do you know whether changing the preference resulted in a merge of the files? Or were the files discarded?

Is it possible to have tcsh put the history into a single file? My home directory gets crowded anytime I show hidden files.

I tried the following from here but it still generates more than one file.

Take care to exit or key Control-D.

(Don't simply close terminal tabs/windows, if the terminal application does not do what's required when closing.)

I have just one stray file, which might have been from a crash a few months ago:

% echo $0
/bin/tcsh
% ls -hl ~/.history*
-rw-------  1 grahamperrin  grahamperrin    69K  4 Apr 12:46 /home/grahamperrin/.history
-rw-------  1 grahamperrin  grahamperrin     0B 29 Nov 07:37 /home/grahamperrin/.history.10857158
%

I need to take back what I said. It did work, I just had history files from before still.
I didn't want to have to type exit every time I close a terminal, so this is much better.
