How can I see all of the bash history?
You should look into the histappend shell option and the -a flag to history:
histappendIf set, the history list is appended to the file named by the value of the
HISTFILEvariable when the shell exits, rather than overwriting the file.
history
-aAppend the "new" history lines (history lines entered since the beginning of the current bash session) to the history file.
If you put history -a into your PROMPT_COMMAND, you'll get an always-up-to-date .bash_history file.
try this:
Edit your .bashrc and append this to it's end:
shopt -s histappendPROMPT_COMMAND="history -n; history -a"unset HISTFILESIZEHISTSIZE=2000source: http://subbass.blogspot.com.br/2009/10/howto-sync-bash-history-between.html
