How to copy single file for example index.html

from source

/backup/cpbackup/daily/a1/homedir/public_html/index.html
/backup/cpbackup/daily/b2/homedir/public_html/index.html
/backup/cpbackup/daily/c3/homedir/public_html/index.html
/backup/cpbackup/daily/d4/homedir/public_html/index.html
/backup/cpbackup/daily/e5/homedir/public_html/index.html
/backup/cpbackup/daily/f6/homedir/public_html/index.html

to destination

/home/a1/public_html/index.html
/home/b2/public_html/index.html
/home/c3/public_html/index.html
/home/c4/public_html/index.html
/home/e5/public_html/index.html
/home/f6/public_html/index.html

cp command can't do this to copy all files to the same directory for each user , so how can i do it ?

You could use a shell loop (copy/paste this into a terminal window):

for user in a1 b2 c3 c4 e5 f6; do
 cp -p "/backup/cpbackup/daily/$user/homedir/public_html/index.html" \
    "/home/$user/public_html/";
done

The -p flag makes cp preserve the attributes (owner,group, timestamp) of the copied files.

If you want to do this for all users (i.e. all sub directories of /backup/cpbackup/daily/) you can do something like this which avoids manually entering the usernames:

for dir in /backup/cpbackup/daily/*; do user=$(basename $dir);
    cp -p "/backup/cpbackup/daily/$user/homedir/public_html/index.html" \
    "/home/$user/public_html/";
done
