( #3333=superdoc: print w/ replies, xml ) Need Help??
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...
