# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output. So make sure this doesn't display
# anything or bad things will happen!
# Test for an interactive shell. There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.

# This does mean sessions get interleaved when reading later on, but this
# way the history is always up to date. History is not synced across live
# sessions though; that is what `history -n` does.
# Disabled by default due to concerns related to system recovery when $HOME
# is under duress, or lives somewhere flaky (like NFS). Constantly syncing
# the history will halt the shell prompt until it's finished.
