CONFIGURATION EXPLANATION
|
|
=========================
|
|
`hh` works best with the optional configuration described in this section.
|
|
You can configure `hh` just by running:
|
|
```bash
|
|
hh --show-configuration >> ~/.bashrc
|
|
```
|
|
|
|
CONFIGURATION OPTIONS
|
|
---------------------
|
|
Bind `hh` to a BASH key e.g. to `Ctrl-r`:
|
|
```bash
|
|
bind '"\C-r": "\C-ahh \C-j"'
|
|
```
|
|
or `Ctrl-Alt-r`:
|
|
```bash
|
|
bind '"\e\C-r":"\C-ahh \C-j"'
|
|
```
|
|
or `Ctrl-F12`:
|
|
```bash
|
|
bind '"\e[24;5~":"\C-ahh \C-j"'
|
|
```
|
|
bind `hh` to `Ctrl-r` only if this is interactive shell:
|
|
```bash
|
|
if [[ $- =~ .*i.* ]]; then bind '"\C-r": "\C-a hh \C-j"'; fi
|
|
```
|
|
|
|
To determine the character sequence emitted by a pressed key in terminal,
|
|
type `Ctrl-v` and then press the key. Check your current bindings using:
|
|
```bash
|
|
bind -S
|
|
```
|
|
|
|
Get `hh` in more colors:
|
|
```bash
|
|
export HH_CONFIG=hicolor
|
|
```
|
|
show normal history by default (instead of metrics-based view):
|
|
```bash
|
|
export HH_CONFIG=rawhistory
|
|
```
|
|
show favorites by default (instead of metrics-based view):
|
|
```bash
|
|
export HH_CONFIG=favorites
|
|
```
|
|
make search case sensitive (insensitive by default):
|
|
```bash
|
|
export HH_CONFIG=casesensitive
|
|
```
|
|
show warnings:
|
|
```bash
|
|
export HH_CONFIG=warning
|
|
```
|
|
show debug messages:
|
|
```bash
|
|
export HH_CONFIG=debug
|
|
```
|
|
more colors and case sensitive search:
|
|
```bash
|
|
export HH_CONFIG=hicolor,casesensitive
|
|
```
|
|
|
|
Increase the size of history:
|
|
```bash
|
|
export HISTFILESIZE=10000
|
|
export HISTSIZE=${HISTFILESIZE}
|
|
```
|
|
Variables defined above increase the number of history items and history file size
|
|
(default value is 500).
|
|
|
|
Ensure syncing (flushing and reloading) of `.bash_history` with in-memory
|
|
history:
|
|
```bash
|
|
export PROMPT_COMMAND="history -a; history -n; ${PROMPT_COMMAND}"
|
|
```
|
|
|
|
Force appending of in-memory history to `.bash_history`
|
|
(instead of overwriting):
|
|
```bash
|
|
shopt -s histappend
|
|
```
|
|
|
|
Use leading space to hide commands from history:
|
|
```bash
|
|
export HISTCONTROL=ignorespace
|
|
```
|
|
Suitable for a sensitive information like passwords.
