Did a bit of searching already but cannot seem to find an elegant way of doing this. I'd like to be able to search through a list like below and only end up with a plain text output file containing on the domain name, no http:// or anything after the /
So a list like this:
http://7wind.ru/file/Behind+the+dune/
http://aldersgatencsc.org/open.php?utm_source=5r2ke0ow6k&utm_medium=qqod2h9a88&utm_campaign=2d1hl1v8c5&utm_term=mz34ligqc4&utm_content=bgi71kl5oy
http://amunow.org/test.php?utm_source=5r2ke0ow6k&utm_medium=qqod2h9a88&utm_campaign=2d1hl1v8c5&utm_term=dhxg1r4l76&utm_content=tr71txtklp
I want to end up with plain text output file like this.
7wind.ru
aldersgatencsc.org
amunow.org
Given:
$ echo "$txt"
http://7wind.ru/file/Behind+the+dune/
http://aldersgatencsc.org/open.php?utm_source=5r2ke0ow6k&utm_medium=qqod2h9a88&utm_campaign=2d1hl1v8c5&utm_term=mz34ligqc4&utm_content=bgi71kl5oy
http://amunow.org/test.php?utm_source=5r2ke0ow6k&utm_medium=qqod2h9a88&utm_campaign=2d1hl1v8c5&utm_term=dhxg1r4l76&utm_content=tr71txtklp
You can use cut:
$ echo "$txt" | cut -d'/' -f3
7wind.ru
aldersgatencsc.org
amunow.org
Or, if your content is in a file:
$ cut -d'/' -f3 file
7wind.ru
aldersgatencsc.org
amunow.org
Then redirect that to the file you want:
$ cut -d'/' -f3 file >new_file
