Sort & Remove Duplicates
This will sort and remove duplicate commands from your .bash_history file in the /root directory, as well as reducing it file size. After you execute the command below, you should edit the file and remove any commands or lines that have errors in them so they aren't executed accidentally.
sort -u /root/.bash_history -o /root/.bash_history
Expand memory of you .bash_history
Expand the memory of your .bash_history to 2000 lines adding this on your .bashrc:
export HISTFILESIZE=2000 export HISTSIZE=2000
Easy search using arrows
Create a .inputrc, or edit your /etc/inputrc, with :
"\e[A": history-search-backward "\e[B": history-search-forward
Next logon you'll be able to search command by start to write them and use up/down arrows.
"\e[1;5A": history-search-backward "\e[1;5B": history-search-forward
Will allow you to use ctrl+up/down arrows (and your up/down arrows will work as usual).
