Learning Sed Is Beneficial For Linux Users

[@gordonbai5320]

sed and AWK are the first two tools I learned in undergraduate Linux class. They are so important, glad to see some brilliant recaps from DT!

[@tweakernation]

@@try1785 I'm pretty sure any college with a Computer Science program has Linux classes

[@gordonbai5320]

@@try1785 It's a class called Computer Software and System, sound pretty generic but it only focused on UNIX-like OS usage and history. The professor at the time was like, hey I think our students need to know these so let's open this course. Guess it varies among colleges. Now students have more choices, like DT's videos or MIT's popular 'missing semester'.

What works when you want to search for a word is to use the boundary characters, which happen to be \< for left and \> for right. So if you search for the sequence \, it's gonna try to find the word red alone, not included in another word.

[@ChucklesMcGee780]

brother DT, i want to thank you for making these videos. i swapped over full time to linux around 2 months ago. your videos have taught me so much, and i now have a desktop that looks incredible, that does incredible things. hands down my favourite linux creator in the tube. keep up the amazing work!!!!!

[@AlastairMontgomery]

Been using sed for years, it's always good to watch how other people use it, you tend to pick up a few things you didn't know.

[@voytechj]

When creating sed regex expression it's a good idea to check what has been modified: $ sed '...' inputfile | diff inputfile you can pipe it further to a program that colorizes text: $ sed '...' inputfile | diff inputfile | bat -l diff For vim users you can use vimdiff (easier side by side comparison), but "process substitution" has to be used to trick vim that pipe is a file: $ vimdiff inputfile

[@commentarysheep]

I knew all of the other Linux CLI utilities, but I always found the syntax of ‘sed’ funky. Thank you for your excellent explanation, DT! It’s way more efficient than using my text editor’s built-in search and replace feature!

[@Eydamos]

I recently saw your awk video and now this sed video. Both are really great and I have learned a lot. Just one thing I want to point out as I had this issue just this week: If you have a big file e.g. let's say 3Gb log file and want to have 1000 line starting at line 30000 sed is a lot quicker then awk with this. In my test `sed -n '30000,31000p' file.log` took like 3 seconds while `awk 'NR==30000,NR==31000 {print $0}' file.log' took almost a minute

[@TheSulross]

when -i option was added to sed, that was life changing - and that can use -e to specify multiple expressions to apply on the stream - sed is kind of like the single most potent unixy power tool

[@arrtemfly]

that's a very nice tutorial! thanks also i've noticed the lighting looks like you're in a proper studio on a photo shoot or something, cool stuff

[@PrashantKumardaniel]

Your videos are very comprehensive and upto the point. Keep it up

Srs, if you want to see some masterful sed code, check out games written in sed. Tetris, Breakout, Chess, etc. It’s humbling and trippy looking at the source.

[@thelostrider1]

Would love to see DT talk more about shell scripting but in a more advanced way

[@fennecbesixdouze1794]

If you're using GNU then you can match an exact word using /\bword\b/. The anchor "\b" represents a word boundary. You can also use /\/.

[@altermetax]

If you want to search for a word instead of a string, surround the word with \b. For example: sed 's/\bred\b/green/'

I want to add this sed, I use this to edit my host file. This will essentially add a line of text after the first match pattern. For example ==== sed -i '0,/pattern/!b;//a[the text u want to add]' filename

[@damian_madmansnest]

for me an eye opener on sed was learning vim’s ex mode. sometimes it’s even faster to filter lines in vim through sed instead of running a similar vim ex command.

[@nicholifamadico6619]

Hi, may I ask how did you make your CLI show a type-ahead suggestion? Like for example when you started typing the command "sed", it already shows something like a format of what to type next in grey color. Is it from history? Thanks in advance!

[@fabrice9848]

@13:21 I understand how this command works But I don't get why it doesn't work if we replace the * with a + we're looking for one or more spaces at the end of each line, so it should work when using + instead of * what am I missing here ?

[@hernanfelipediaz566]

I actually think that the space search pattern is not optimised, it is way better to use a '+' since it will only act when it is 1 or more instead of 0 or more. With '*', the command will make an action every single line, that's unefficient.

[@daniahmed]

If i want to add a letter or a string at start of every line, then what would the command look like?

It seems to use a non standard version of regular expressions.

I admire the cooperation of your rapid thinking and typing commands, but for me 0.75 speed is ideal.
