Useful bash history command shortcuts

I have found these shortcuts very useful to navigate the bash history. Saves time.

Something else - for fun. Add this line to the bottom of the .bashrc file :-
PS1="\`if [ \$? = 0 ]; then echo \[\e[33m\]^_^\[\e[0m\]; else echo \[\e[31m\]O_O\[\e[0m\]; fi\`[\u@\h:\w]\\$ "

Now when a command is successfully executed, the prompt will show a happy face, and if the command is bad a sad face is shown.

 

Nice - thanks for sharing!
