hs9001 (history search 9001) is an easy, quite simple bash history enhancement. It simply writes all your bash commands into an sqlite database. You can then search this database.
It improves over bash's built-in history mechanism as it'll aggregate the shell history of all open shells, timestamp them and also record additional information such as the directory a command was executed in.
hs [search terms]
You can further filter with options like -cwd, -after and so on...
For a full list, see -help.
hs -cwd .
Lists all commands ever entered in this directory
hs -today -cwd . git
Lists all git commands in the current directory which have been entered today.
Also, it (by default) replaces bash's built-in CTRL-R mechanism, so hs9001's database will be used instead of bash's limited history files.
When in reverse-search mode, you can only search the history of the current directory by pressing CTRL+A and then "w".
Latest release can be installed using apt
curl -s https://repo.quitesimple.org/repo.quitesimple.org.asc | sudo apt-key add -
echo "deb https://repo.quitesimple.org/debian/ default main" | sudo tee /etc/apt/sources.list.d/quitesimple.list
sudo apt-get update
sudo apt-get install hs9001
wget https://repo.quitesimple.org/repo%40quitesimple.org-5f3d101.rsa.pub -O /etc/apk/repo@quitesimple.org-5f3d101.rsa.pub
echo "https://repo.quitesimple.org/alpine/quitesimple/" >> /etc/apk/repositories
apk update
apk add hs9001
go build
#move hs9001 to a PATH location
Add this to .bashrc
eval "$(hs9001 bash-enable)"
This will also create a hsalias so you have to type less in everyday usage.
By default, every system user gets his own database. You can override this by setting the environment variable for all users that should write to your unified database.
export HS9001_DB_PATH="/home/db/history.sqlite"
