I just published a screencast on advanced command-line tips from a short talk I gave last year. I try to keep my screencasts brisk to avoid wasting anybody's time, but I also understand some would prefer to have the content in a more skimmable format; hence this post.

Note that this is more an info-dump than a tutorial, so if any of these topics are unfamiliar, I suggest watching how I use them in the video.

My advanced bash/CLI tips:

• history expansion with !!, which is a reference to the previous command
• for loops, to run a command for each of many items
• process substitution with <(), useful to have more than one input stream to a single process
• the fc or 'fix command' utility, where you can edit multiple previous commands in your editor of choice
• making a change to the previous command with ^old^new or globally with !!:gs/old/new/
• the yank-last-arg readline command, typically bound to M-., which inserts the last word of the previous command at your cursor position
