You might not even like rsync. Yeah it’s old. Yeah it’s slow. But if you’re working with Linux you’re going to need to know it.
In this video I walk through my favorite everyday flags for rsync.

Here’s a companion blog post, where I cover a bit more detail: https://vkc.sh/everyday-rsync
Also, @BreadOnPenguins made an awesome rsync video and you should check it out: https://www.youtube.com/watch?v=eifQI5uD6VQ
Lastly, I left out all of the ssh setup stuff because I made a video about that and the blog post goes into a smidge more detail. If you want to see a video covering the basics of using SSH, I made one a few years ago and it’s still pretty good: https://www.youtube.com/watch?v=3FKsdbjzBcc

This is why I still don’t know
sed
andawk
syntax lol. I eventually get the data in the shape I need and then move on, and never imprint how they actually work. Still feel like a script kiddie every time I use them (so once every few years).sed
can do a bunch of things, but I overwhelmingly use it for a single operation in a pipeline: thes//
operation. I think that that’s worth knowing.will replace all the first text in each line matching the regex “foo” with “bar”.
That’ll already handle a lot of cases, but a few other helpful sub-uses:
will replace all text matching regex “foo” with “bar”, even if there are more than one per line
will take the text inside the backslash-escaped parens and put that matched text back in the replacement text, where one has ‘\1’. In the above example, that’s finding all hexadecimal strings and prefixing them with ‘0x’
If you want to match a literal “/”, the easiest way to do it is to just use a different separator; if you use something other than a “/” as separator after the “s”,
sed
will expect that later in the expression too, like this:will replace all instances of a “/” in the text with “SLASH”.
