inspired by What one-liners do people actually use? i wrote a little utility for bash:
addhist.pl:
#!/usr/bin/perl
use strict;
use warnings;
my @lines = <>;
pop @lines;
my $hist = join '', @lines;
my $history = "$ENV{HOME}/.oneliners";
$hist =~ s/\A\s*\d+\s+//;
open my $fh, ">>", $history or die $!;
print $fh $hist;
close $fh;
# put these in your .bashrc
alias addhist="history 2 | addhist.pl"
alias readhist="history -r ~/.oneliners"
$ perl -wle'something short and useful'
$ addhist
[hours or days later...]
$ readhist
$ !! # will get you your last saved oneliner from above
i can't get this to work with "oneliners" that have more than one line, though...

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
