# 1) Prevent recursion, and multiple sourcing of profiles with the BYOBU_SOURCED_PROFILE environment variable.
|
|
# 2) Respect environment variables (LC_BYOBU and BYOBU_DISABLE) passable over SSH to disable
|
|
# Byobu launch. This puts that configurability on the SSH client,
|
|
# in addition to the server.
|
|
# To use over SSH, your /etc/ssh/sshd_config and /etc/ssh/ssh_config
|
|
# must pass this variable with AcceptEnv and SendEnv.
|
|
# Note that LC_* are passed by default on Debian/Ubuntu, we'll optionally
|
|
# support LC_BYOBU=0
|
|
# And in your local bashrc:
|
|
# $HOME/.bashrc: export LC_BYOBU=0
|
|
# or edit your sshd_config, ssh_config, and set:
|
|
# $HOME/.bashrc: export BYOBU_DISABLE=1
