Don't search history by grepping ~/.bash_history, or repeatedly hitting the up arrow, instead use CTRL+r (or '/' in vi-mode) for search-as-you type. You can immediately run the command by pressing Enter.

That is ~brilliant~! 20 years (on and off) of playing with *nix and I'd not seen that one..!

Whilst I use Ctrl-R often, sometimes grepping history is easier to get the exact command you want, so I setup an alias

alias ghis='history | grep'

and then use !<n> ,where n = history #

If you run "cat /proc/acpi/thermal_zone/THRM/temperature", then later want to run the same command, you can use a history expansion.
gives you the most recent bash history line that begins with "cat". You can also use a wildcard (?)

And then try CTRL-O instead of Enter.
