Hi Guys,

You can get this on google very easily.
scp is used for remote copy, if you want to copy in same system, cp is enough. It is not like like scp will do it fast.
Code:
scp /path/of/directory/* IP:/path/of/desstination/directory
Suppose you source path is /tmp/user/myfiles and destination system's IP is 192.168.1.9 and destination folder is in /tmp/user2
Code:
scp  /tmp/user/myfiles/* 192.168.1.9:/tmp/user2
It will copy only files, if youw ant to copy directory, use scp -r

maybe something like:
Code:
scp file.1 user@host:/whatever/floats/your/boat &
scp file.2 user@host:/whatever/floats/your/boat &

yes something like this.

but is there any switch which will be used to transfer all files parrally than one after the another?

not sure what you are asking but by putting both transfers in the background (&) it will trigger the system to run the 2 scp programs at the same time.

Having parallel uploads will likely not boost upload speed, since that should already be capped with one upload.

why not
Code:
scp file1 file2 file3 file4 file5 user@host:/path/to/destination/
It works for me...

It is not parallel copy. It copies another file when it completes first file. It is doing too fast that's why it looks like parallel copy.
Try to copy multiple 700mb files then you will get, it starts another when it completes first.
Parallel copy is something like this...

but if you have a 25 mb/s connection then 5 files with a throughput of 5 mb/s each would take the same time.
