En su momento me hice una pequeña funcion que lo hace:

buscame() { cat ~/.bash_history | grep -i "$*" | grep -i -v "buscame" }

Basta con añadirla al .bashrc

MEJORA: El comando history ya te vuelca el historial, asi que simplemente

history | grep -i "palabra clave"

Keith Amling (25/09/2005, 13:27) If you use "set -o vi" you can use "/" from normal mode. For example to search the history for foo from insert mode you would press "<ESC>/foo<ENTER>" and then "n" to go to the next match. If you use vim already, "set -o vi" would be easy to learn, but if you use emacs or another editor it would be difficult.
