if you only want domains names sss.com or edd.com and not the whole line use

| Posted by fweikeong, 01-09-2008, 04:44 AM | | You would want to explore the 'cut' linux shell command.
For example, your data is separated by a white space in between column, so you can do a cut command :-
cut -d" " -f1
-d" " means delimiter is " ".
-f1 means pick field 1 from the every row in the file_name.
Hope that helps.

cat yourfile.txt |awk '{print $1}'
would give only the domain names at position #1 (devided by spaces on default).
cat yourfile.txt | awk '{print $3 $1}'
would give the data and the domain name like:
01/09/2008 sss.com
01/09/2008 edd.com
hope this helps. awk has a whole bunch of other nice options too.

The above command puts the result into the file /root/file2.txt
