Unfortunately you cannot recover it, sorry.

For unlimited Bash history consult this link, and if you stall somewhere, edit your question in detail to help you out.

In short, if they do not already exist, you should add two lines to your .bashrc:

HISTSIZE=
HISTFILESIZE=

If your username is vitor, under normal configuration the full path of .bashrc will be /home/vitor/.bashrc.

  • Ok, but how can I make this? Disappear all the history command and in ./bash_history? And how can I stop the history disappear? – Vitor Mazuco May 27 '14 at 18:32
  • In my basrc is # .bashrc

    User specific aliases and functions

    alias rm='rm -i' alias cp='cp -i' alias mv='mv -i'

    Source global definitions

    if [ -f /etc/bashrc ]; then . /etc/bashrc fi

  • Since I do not see any HISTSIZE= or HISTFILESIZE= lines, you can add those two lines at the end of the file. Do not add anything after the equal sign (=). For verification, start a new shell and type a few commands. Watch how .bash_history changes appending the command you just wrote. You should be able to keep the history after reboot. Try it and let us know. ;) – Konstantinos May 27 '14 at 18:50
