Embedded Files
Use sftp or rsync for copying files between hosts. The scp protocol is no longer considered secure.

cp
cp
To time how long it takes to make a copy of a file...
time cp myfile1.tst myfile2.tst
rsync
rsync
To recursively copy a directory and its contents including progress reporting and timing...
time rsync -a --progress /mymount1/mydir /mymount2
time rsync -rlptgoD --progress /mymount1/mydir /mymount2
The two commands above are functionally identical. i.e. -a is the same as -rlptgoDrsync mydir1 mydir2
Copies mydir1 into mydir2 and misses out mydir1/mysubdir
rsync mydir1/* mydir2
skipping directory mysubdir
Duplicates the files in mydir1 to mydir2 but misses out mydir1/mysubdir
rsync -r mydir1/* mydir2
Successfully duplicates mydir1 to mydir2
rsync -ri mydir1/* mydir2
>f+++++++++ myfile1>f+++++++++ myfile2cd+++++++++ mysubdir/>f+++++++++ mysubdir/myfile3
Successfully duplicates mydir1 to mydir2
rsync -ri mydir1/* mydir2
>f..T...... myfile1>f..T...... myfile2>f..T...... mysubdir/myfile3
Running the same command again without removing mydir2 results in output as shown.
