copied!<p>When running commands, sometimes I'll want to run a command with the previous ones arguments. To do that, you can use this shortcut:</p> <pre><code>$ mkdir /tmp/new $ cd !!:* </code></pre> <p>Occasionally, in lieu of using find, I'll break-out a one-line loop if I need to run a bunch of commands on a list of files. </p> <pre><code>for file in *.wav; do lame "$file" "$(basename "$file" .wav).mp3" ; done; </code></pre> <p>Configuring the command-line history options in my .bash_login (or .bashrc) is really useful. The following is a cadre of settings that I use on my Macbook Pro. </p> <p>Setting the following makes bash erase duplicate commands in your history:</p> <pre><code>export HISTCONTROL="erasedups:ignoreboth" </code></pre> <p>I also jack my history size up pretty high too. Why not? It doesn't seem to slow anything down on today's microprocessors.</p> <pre><code>export HISTFILESIZE=500000 export HISTSIZE=100000 </code></pre> <p>Another thing that I do is ignore some commands from my history. No need to remember the exit command. </p> <pre><code>export HISTIGNORE="&:[ ]*:exit" </code></pre> <p>You definitely want to set histappend. Otherwise, bash overwrites your history when you exit.</p> <pre><code>shopt -s histappend </code></pre> <p>Another option that I use is cmdhist. This lets you save multi-line commands to the history as one command.</p> <pre><code>shopt -s cmdhist </code></pre> <p>Finally, on Mac OS X (if you're not using vi mode), you'll want to reset <CTRL>-S from being scroll stop. This prevents bash from being able to interpret it as forward search. </p> <pre><code>stty stop "" </code></pre>
