Byobu does not read aliases defined in /etc/profile.d or in .profile

OK, after submitting this, I found out that its a duplicate of 525552

So modifying these two files to use the --login option fixes my problem.

bin/byobu-shell
 [ -n "$SHELL" -a -x "$SHELL" ] && exec "$SHELL" --login || exec /bin/sh --login

share/byobu/profiles/tmux
 set -g default-command $SHELL --login

The first one fixes the initial window and the second one fixes any subsequent windows/splits

However, tmux specifically states in the changed file that it wishes, _not_ to read .profile again:
```
# Must set default-command to $SHELL, in order to not source ~/.profile
# BUG: Should *not* hardcode /bin/bash here
set -g default-command $SHELL
```
And indeed, when running tmux on its own (without the --login modification) and adding new windows/splits the aliases from /etc/profile.d/ end .profile are inherited from the original session.

So, somewhere there seems to be a discrepancy how byobu initializes tmux windows.

This is also not a stable solution since as soon as byobu is updated these files will be overwritten.

Do you have a status on this ?
This is still relevant on Debian 10

My current fix is to manually source /etc/profile when needed...

Seconding this. I confirm it is also present in both Ubuntu 18.04.5 LTS and Ubuntu 20.04.1 LTS.

Thanks for the comments.

I was able to confirm this bug by doing:

# cat >> /etc/profile <<EOF
alias mytest="echo hello"
EOF
# byobu-shell
# mytest
bash: mytest: command not found

This is also present in Groovy and Hirsute, and upstream hasn't replied yet.

Hi,

I could be able to reproduce the issue with Sergio's steps in Impish and Jammy as well.

To add to the discussion, it looks like byobu also ignores my ~/.bashrc file. It is especially important for me to get this working so I can use Lmod and Spack inside byobu, both of which I load through my ~/.bashrc file with the following snippet:

# Add Lua paths
LUAROCKS_PREFIX=/usr/local
export LUA_PATH="$LUAROCKS_PREFIX/share/lua/5.3/?.lua;$LUAROCKS_PREFIX/share/lua/5.3/?/init.lua;;"
export LUA_CPATH="$LUAROCKS_PREFIX/lib/lua/5.3/?.so;;"

# Lmod
if [ -z "$_INIT_LMOD" ]; then
  # Clear previous definitions of 'module'
  type module > /dev/null 2>&1
  if [ "$?" -eq 0 ]; then
    clearLmod --quiet # Purge all modules and completely remove old Lmod setup
  fi
  export _INIT_LMOD=1 # guard variable is crucial, to avoid breaking existing modules settings
  # Activate Lmod
  export BASH_ENV=/opt/lmod/lmod/init/bash
  source ${BASH_ENV}
  # Load initial modules
  export MODULEPATH=/opt/modulefiles/Compiler:/opt/modulefiles/Linux
  export MODULEPATH_ROOT=/opt/modulefiles
  export LMOD_SYSTEM_DEFAULT_MODULES=gcc:spack
  module --initial_load --no_redirect restore
fi

# Spack
. /opt/spack/share/spack/setup-env.sh
