Shell Save command history in sh terminal

[Schroter]

Hi All,
I am trying to save history in FreeBSD 14.2 sh terminal because it does not appear to be saving history across sessions. Below is the code and resulting .profile file

# Save sh terminal command history
echo 'HISTFILE=~/.sh_history' >> /home/michael/.profile
echo 'HISTSIZE=1000' >> /home/michael/.profile
echo 'trap "history -a" EXIT' >> /home/michael/.profile
echo 'history -r "$HISTFILE"' >> /home/michael/.profile
chown michael:michael /home/michael/.profile

Shell:

michael@cs:~ $ echo $SHELL
/bin/sh

.profile file:

#
# .profile - Bourne Shell startup script for login shells
#
# see also sh(1), environ(7).
#

# These are normally set through /etc/login.conf.  You may override them here
# if wanted.
# PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:$HOME/bin; export PATH

# Setting TERM is normally done through /etc/ttys.  Do only override
# if you're sure that you'll never log in via telnet or xterm or a
# serial line.
# TERM=xterm;     export TERM

EDITOR=vi;       export EDITOR
PAGER=less;      export PAGER

# set ENV to a file invoked each time sh is started for interactive use.
ENV=$HOME/.shrc; export ENV

# Let sh(1) know it's at home, despite /home being a symlink.
if [ "$PWD" != "$HOME" ] && [ "$PWD" -ef "$HOME" ] ; then cd ; fi

# Query terminal size; useful for serial lines.
if [ -x /usr/bin/resizewin ] ; then /usr/bin/resizewin -z ; fi

# Display a random cookie on each login.
if [ -x /usr/bin/fortune ] ; then /usr/bin/fortune freebsd-tips ; fi
HISTFILE=~/.sh_history
HISTSIZE=1000
trap "history -a" EXIT
history -r "$HISTFILE"

However, still the terminal does not record the command history.

Thanks & Best Regards

trap "history -a" EXIT
history -r "$HISTFILE"

But sh(1) doesn't have built-in history command. Where did you get this?

Some month go sh has been updated with a history function.For curiosity I have tried its function.
fc -l lists the last commands. history -a appends to the history which can also be monitored by checking the histfile. The default is ~/.sh:history.

The strange thing is that history works but triggers an error message. It is also not mentioned in sh().

 

[covacat]

is your .sh_history owned by you ?

It is also not mentioned in sh(1).

The 'history' command is an alias set in ~/.shrc.

alias history='fc -l'

 

[eseipi]

history -a appends to the history which can also be monitored by checking the histfile.

Ah, as SirDice mentioned, I missed the alias from the default ~/.shrc. Nevertheless, the OP's config is clearly wrong, as fc doesn't have appending/reading functionality similar to history -a|-r in bash(1). Furthermore, the whole history capability in sh(1) should work without any additional configuration ( HISTFILE and HISTSIZE defaults to ~/.sh_history and 100, respectively).
