You can print a command with:

!2500:p

But how do I append that command to a file? I thought:

!2500:p >> .bashrc

But that just prints everything including the ">> .bashrc" to stdout.

! repeats the numbered command, so you need to echo it. Use the :q modifier to quote the history substitution properly.

echo !2500:q >> .bashrc

Thanks, that works, but how do I preserve quotes and special characters. E.g. ls -al | grep "[[:space:]]\." – gregh Apr 18 '13 at 20:26
    
That's a bit more tricky – parkydr Apr 18 '13 at 21:02
