How to extract particular field space separately in shell script using sed command

Input File : Test.txt

-rw-r--r--  1 dev dev  93K Sep 18 05:37 Server-23091805496-2-AC.log
-rw-r--r--  1 dev dev  40K Sep 18 05:44 ServerM-23090331-5709-log.log
-rw-r--r--  1 dev dev 484K Sep 18 05:46 Server-280334-12570-log.log
-rw-r--r--  1 dev dev 235K Sep 18 05:47 Server-233405500-1-AC.log

Output in 1st File :

Sep 18 05:37 Server-23091805496-2-AC.log
Sep 18 05:44 ServerM-23090331-5709-log.log
Sep 18 05:46 Server-280334-12570-log.log
Sep 18 05:47 Server-233405500-1-AC.log

Output in 2nd File :

Server-23091805496-2-AC.log
ServerM-23090331-5709-log.log
Server-280334-12570-log.log

Tried Below :
1. sed ‘s/ /\n/g’ Test.txt
2. ls -ltr | grep "Sep 18 08:" |sed -n ‘1p’|cut -d ‘ ‘ -f2

>Solution :

One answer could be:

sed <input.txt -e 's/.*K //g;w file1.txt' -e 's/.* //g;' >file2.txt

Or better:

sed <input.txt -e '
   s/^\([^[:space:]]\+[[:space:]]\+\)\{5\}//;
   w file1.txt' -e '
   s/\([^[:space:]]\+[[:space:]]\+\)\{3\}//;' >file2.txt

Where

• sed is run only once, without any fork to other tool,

• 1st removing everything until K in first proposal,

  removing non-spaces followed by spaces, repeated 5 times, in second proposal

• then w write to file file1.txt

• At this point, script end with second quote, then a second script start with -e sed argument.

• Removing everything until last space in first proposal,

  removing non-spaces followed by spaces, repeated 3 times, in second proposal

• Then send sed‘s standard output to file2.txt
