<title>History</title> |
| 163 |
<body> |
| 164 |
Unfortunately default <c>zsh</c> configuration in Gentoo does not include commands |
| 165 |
history support. Due to the fact that working with a shell with history |
| 166 |
disabled is far more than frustrating, we should enter the following |
| 167 |
commands: |
| 168 |
|
| 169 |
<pre caption="Basic history configuration"> |
| 170 |
% <i>export HISTSIZE=2000</i> |
| 171 |
% <i>export HISTFILE="$HOME/.history"</i> |
| 172 |
|
| 173 |
<comment>(otherwise history won't be saved)</comment> |
| 174 |
% <i>export SAVEHIST=$HISTSIZE</i> |
| 175 |
</pre> |
| 176 |
|
| 177 |
It is very comfortable to search commands in history using up/down |
| 178 |
arrow keys, especially after typing few first letters of desired command |
| 179 |
under shell. For example: |
| 180 |
|
| 181 |
<pre caption="History searching based on the first letters of the commands"> |
| 182 |
<comment>(Do not press Enter after typing)</comment> |
| 183 |
% <i>vim /etc/</i> |
| 184 |
<comment>(Now press up arrow key)</comment> |
| 185 |
% <i>vim /etc/fstab</i> |
| 186 |
<comment>(Press up arrow key once again)</comment> |
| 187 |
% <i>vim /etc/X11/xorg.conf</i> |
| 188 |
</pre> |
| 189 |
|
| 190 |
<p> |
| 191 |
To enable the feature above enter the following commands: |
| 192 |
</p> |
| 193 |
|
| 194 |
<pre caption="Setting context searching"> |
| 195 |
% <i>bindkey `tput kcuu1` history-beginning-search-backward >/dev/null 2>&1</i> |
| 196 |
% <i>bindkey `tput kcud1` history-beginning-search-forward >/dev/null 2>&1 </i> |
| 197 |
</pre> |
| 198 |
|
| 199 |
<p> |
| 200 |
To prevent history from recording duplicated entries (such as <c>ls |
| 201 |
-l</c> entered many times during single shell session) set |
| 202 |
<c>hist_ignore_all_dups</c> option. |
| 203 |
</p> |
| 204 |
|
| 205 |
<pre caption="Setting ignoring of duplicates "> |
| 206 |
% <i>setopt hist_ignore_all_dups</i> |
| 207 |
</pre> |
| 208 |
|
| 209 |
<p> |
| 210 |
Is also a useful trick to prevent particular entries from being recorded |
| 211 |
into a history by preceding them with at least one space. |
| 212 |
</p> |
| 213 |
|
| 214 |
<pre caption="Preventing particular entry from being recorded"> |
| 215 |
% <i>setopt hist_ignore_space</i> |
| 216 |
|
| 217 |
<comment>(This command won't be recorded. Note an extra space before it.)</comment> |
| 218 |
% <i> cat /proc/i/do/not/want/to/remember</i> |
| 219 |
