Two Powerful Command Line Utilities 'cut' And 'tr'

Recently, I've made videos on command line utilities like 'awk' and 'sed'. In this video, I cover two powerful command line utilities--'cut' and 'tr'. The 'cut' command removes sections from each line of a file. The 'tr' command translates or deletes characters from standard input.

I wouldn’t even know how to find these utilities so continuing this series of videos is actually heartwarming

@hocky-ham324-zg8zc 3 жыл бұрын

To learn more about these types of utilities, you can run “ls /usr/bin” to find pretty much any program that I assume DT will talk about. There will likely be a lot of programs here, but you can run “man [program]” to find out what it does (most, if not all of these programs should have man entries). For example, if you run “ls /usr/bin”, you will see “tr” come up as a result. So you can run “man tr” which will show a bunch of information on the TLDR of its purpose, and how to use it

This video is fantastic! It's dynamic, full of concrete information, and moves quickly without losing clarity. It strikes a perfect balance, delivering content comprehensibly without rushing through it. Please continue sharing more videos on Linux commands and their combinations!

I never use cut because of the deep dive into awk but had to learn it so I could decipher other peoples scripts. This was informative on what the limitations are for the cut command as I was unaware of how the extra spaces could throw off cut.

@@SkyyySi sure, why not? What may be easy for us may be challenging to others. Also, DT has made videos on many entry-level topics. I mention sort and uniq specifically, because they’re powerful and easy to learn, yet often overlooked.

I would have included "paste" in this video since it's basically the inverse utility of "cut". I also think "paste" is a very useful and often overlooked utility.

@omarmagdy1075 2 жыл бұрын

really like this video but would like to note that sed would can pretty much do what tr did through basic regex knowledge for example you can replace lower case to upper case with this command: *echo "This is a line of text" | sed 's/[a-z]/\U&/g'* and upper to lower with this one: *echo "This is a line of text" | sed 's/[A-Z]/\L&/g'* you could also replicate the compliment function with the carrot symbol ^ inside square brackets like so: *echo "this is some text and numbers 1234" | sed 's/[^0-9]//g'* (This means that anything that is not a digit replace it with empty string) but of course using tr for these tasks would probably be a better idea
