cheat sheets.

Your history:

    % which firefox
    % make
    % ./foo -f foo.conf
    % vi foo.c bar.c

Getting stuff from the last command:

    Full line:     % !!            becomes:   % vi foo.c bar.c
    Last arg :     % svn ci !$     becomes:   % svn ci bar.c
    All args :     % svn ci !*     becomes:   % svn ci foo.c bar.c
    First arg:     % svn ci !!:1   becomes:   % svn ci foo.c

Accessing commandlines by pattern:

    Full line:     % !./f          becomes:   % ./foo -f foo.conf
    Full line:     % vi `!whi`     becomes:   % vi `which firefox`
    Last arg :     % vi !./f:$     becomes:   % vi foo.conf
    All args :     % ./bar !./f:*  becomes:   % ./bar -f foo.conf
    First arg:     % svn ci !vi:1  becomes:   % svn ci foo.c
