Extract parts of the line
I have a long list of lines in a txt file which i'm only interested to extract the list of domains like the colored ones.

Code:
domain.com    domain.com/page   codes $.09 
domain.org     domain.org/page2/  codes $0.10
domain.net     domain.net/page03  codes  $0.05
domain.info    domain.info/page34  codes  $0.11
domain.asia  ....
domain.oi ....
domain.world...

how do i extract these red ones from a text file to another text file? please

Hi,

Try awk '{ print $1 }' input_file > output_file where input is your existing file and output is the name of the file where you want the data.

Regards
