In this episode of Linux Crash Course, we explore the sed command. sed, aka the "stream editor" is an underused command, and that's a shame because it's extremely useful for manipulating text. In this video, I'll show you the basics of the sed command.

I believe the 's' before the search pattern actually stands for "substitute", not "string".

sed is called stream editor, which is what Jay said.

it's important to note that '-i' is a GNU only option - so it won't work on BSD or MacOS etc.

sed 's/\/etc//' paths.txt Yeah, the command can get rather ugly when lots of escaped characters are needed, but it works and it's second nature for me since I often search for spaces and other characters that must be escaped anyway. Still, I appreciate that there is such an option in case someone wants to learn/use a different delimiter. Thanks for the video

Good morning, Jay. Thank you very much for the detailed guides ! I have an old Toshiba Portege 14" Laptop with Kali 10.04 still installed there. Recently, I wanted to use it for a monitoring device and reinstall it but it is giving the "no pae"- error (common for the very old hardware). It doesn't boot from USB, only from CD/DVD. Do you think, I can still use it to install a Linux OS on it (I wouldn't mind being only CLI - I need it just to be able to install software to monitor my network), and which one you would propose if yes ? Thank you in advance. Asen

@swarooprajpurohit110 2 жыл бұрын

You could use a distro which doesn't require pae or install an older version of kali and then upgrade it

Instead of changing the delimiter, you can use the backslash(\) before to escape the slash (/) just like this : sed 's/\/etc//'

I didn't know that you could change the delimiter to a different character. this would have come in handy last year when I took a Unix/Linux course at college
