sed is a stream editor. A stream editor is used to perform basic text transformations on an input stream (a file or input from a pipeline). The most common usage of sed involves substituting a pattern or string for another string. But sed can be used for many tasks. It's a powerful command line utility that should be in everyone's tool bag.

@gordonbai5320 3 года назад

@@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.

@voytechj 2 года назад

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

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

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

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.
