shell history search trick
A command line trick that I love is including a comment on the end to make searching for the command easier.
For example:
echo "crazy command i forget the name of" # my fancy search keywordThe comment is now searchable along with the command itself.
If you're not familiar, history search is typically bound to Ctrl-r, and
typically supported in a fuzzy way by tools like fzf. (Please use fzf! It's a
game changer!)
A real use-case: fixing the linux clock
I can never remember how to fix my linux clock, which slowly drifts.
> There are plenty of other ways to solve this (like encoding this fix as part of your computer's boot, or running it on a cron job). Shrug.
The command is here:
sudo ntpd -qg && sudo hwclock --systohcBut, rather than remember this arbitrary jumble of letters, you can:
sudo ntpd -qg && sudo hwclock --systohc # fix linux clockAnd now I search for it via
Ctrl-r
and typing
fix, and
bada-bam, it's the first one. Thanks, past-me +
fzf!
