Oh Lord, why it's not working, just empty string

seth · 2020-12-11 23:09:07

It's all okay

Obviously not…

grep data-track-url test.txt

Yes the grep has returned me a lot of html to the my console

seth · 2020-12-11 23:14:17

sed -e '/data-track-url/!d' test.txt

Yes that's also shown many HTML strings

seth · 2020-12-11 23:19:40

sed -e '/data-track-url=/!d' test.txt
sed -e '/data-track-url="/!d' test.txt

Ah, fuck… again.

sed -e '/data-track-url=/!d; s/.*data-track-url="\([^"]*\)".*/\1/g' test.txt

</span>=%

Please don't go a way. I really did't get why it not working at all.

Ashley2020 · 2020-12-12 01:17:16

After reinstalling arch all working... thanks to zhs...

Sed is the wrong tool for the job. This sed command will get you at most one desired url from every line that has a data-track-url:

sed -n '/data-track-url/{s/.*data-track-url="\([^"]*\)".*/\1/p;}' test.txt

But if there is more than one data-track-url per line (which thre appears to be) this will fail. The previously attempted use of the 'g' flag for sed will not remedy this.

In this case, piping grep to cut might be the way to go:

grep -o 'data-track-url="[^"]*"' test.txt | cut -d\" -f 2

Ashley, sed is not very good for what you are trying to do, if this is html or xml.
I do not know of ZHS, is this server related?

Hey do I can this one?

cat * | grep -o 'data-track-url="[^"]*"' test.txt | cut -d\" -f 2

Ah ... have you never used a linux/unix system before? The example was acting on test.txt, if you want it to run on all files (in the current working directory) you replace "test.txt" with the asterisk

grep -o 'data-track-url="[^"]*"' * | cut -d\" -f 2

(edit: did you just change your avatar? Great, now I'm not the only one with a creepy forum stalker).
