My bash command history stops working after starting a new tmux session. No previous commands when typing up, down, reverse search, no output from running history.I've confirmed that this happens regardless of the .tmux.conf file being used. The real kicker is that this condition persists beyond tmux ... that is, if I ssh to the server without tmux the bash command history still doesn't work. If I move my .bashrc and .bash_profile files (using the system default) and try again, still no history.I've verified that all the permissions are correct on the history file, my user is both the owner and the group, and even tried setting perms to 777 just to test. For each test I re-executed bash (ie didn't use a subshell).For some context, this happened after my all my files were copied over to a new server.Another clue: In the original shell where I started tmux for the first time, if I exit tmux, the command history still works. It is only new shell sessions that are affected.Some more info:CentOS release 6.7 (Final)GNU bash, version 4.1.2(1)-release (x86_64-redhat-linux-gnu)tmux 1.6 (other server was 1.4)set | grep HIST and histHISTCONTROL=ignoredupsHISTFILE=/home/my_username/.bash_historyHISTFILESIZE=1000HISTSIZE=1000SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitorBASHOPTS=checkwinsize:cmdhist:expand_aliases:extquote:force_fignore:hostcomplete:interactive_comments:login_shell:progcomp:promptvars:sourcepathshopt | grep histcmdhist         onhistappend      offhistreedit      offhistverify      offlithist         offAny help is appreciated!
