Simplified manual page for scp (Unix command line)
SYNOPSIS:
scp [-p] [-v] [-r] [[username@]host:]file … [[username@]host:]file_or_dir
Copies files over the network securely; uses ssh for data transfer, using the same authentication and providing the same security as ssh.
EXAMPLES of USAGE
(The “.colorado.edu'' isn't necessary if
both computers are on the Boulder campus.
Typing a username isn't necessary if you have
the same username on both computers.)
1. “Putting'' a single file
ucsu> scp mydata.dat newton.colorado.edu:NewData.txt
copy file “mydata.dat'' from your current computer/directory to your home directory on newton.colorado.edu,
naming the copy on newton “NewData.txt''.
ucsu> scp mydata.dat newton.colorado.edu:
same thing, but the copied file on newton is named the same as the original (mydata.dat) by default
ucsu> scp mydata.dat amath:/www/courses/8100/2005Spr/lab2.dat
copy file to a specific directory on amath, giving the file a new name there
goldhill.ucar.edu> scp mydata.dat smithjz@amath.colorado.edu:ncar.dat
copy file from your account on goldhill to your home directory on amath,
where your username is different (smithjz)
2. “Getting'' a single file
ucsu> scp newton:mydata.dat ./mydata.dat
copies file “mydata.dat'' from the your home directory on newton to
your current working directory on ucsu
ucsu> scp newton:mydata.dat ./
same thing — it is enough just to indicate the directory (“./'' = my current directory), and
the copied file will be named the same as the original, by default
ucsu> scp smithjz@newton.colorado.edu:research/MYC/mydata.dat ./
gets the file from my “research/MYC'' subdirectory (relative to smithjz's home directory on newton)
3. “Putting'' an entire directory
ucsu> scp -r research newton:MyRsrch/09/
copy directory “research'' recursively (i.e., the directory and all its contents) from ucsu
into a new directory “MyRsrch/09/'' in your home directory on newton
(the directory “MyRsrch'' must already exist).
Sometimes a better alternative is to create a tar file, then copy over
only that single tar file and unpack it on the remote host.
4. “Getting'' an entire directory
ucsu> scp -r smithj@euclid.ucla.edu:MyRsrch/09 ./r9/
copy directory “MyRsrch/09/'' recursively (i.e., the directory and all its contents) from
euclid.ucla.edu (where you are "smithj" into a new directory “r9/'' in your current working directory on ucsu.
Sometimes a better alternative is to ssh to the remote computer, bundle the
files you want into a single tar file, scp that file over, and unpack it where you want the files.
OPTIONS:
-r This option specifies that scp should copy directories recursively — copies all the files & subdirectories,
plus the contents of the subdirectories themselves, etc. The operation does not follow symbolic links.
-p Tells scp to preserve file attributes and timestamps.
-v Makes scp verbose.

NAME scp - secure copy (remote file copy program) SYNOPSIS scp [-pqrvBC46] [-F ssh_config] [-S program] [-P port] [-c cipher] [-i identity_file] [-o ssh_option] [[user@]host1:]file1 [...] [[user@]host2:]file2 DESCRIPTION for data transfer, and uses the same authentication and pro- vides the same security as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication. Any file name may contain a host and user specification to indicate that the file is to be copied to/from that host. Copies between two remote hosts are permitted. The options are as follows: -c cipher Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1). -i identity_file Selects the file from which the identity (private key) for RSA authentication is read. This option is directly passed to ssh(1). -p Preserves modification times, access times, and modes from the original file. -r Recursively copy entire directories. -v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems. -B Selects batch mode (prevents asking for passwords or passphrases). -q Disables the progress meter. -C Compression enable. Passes the -C flag to ssh(1) to enable compression. -F ssh_config Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1). -P port Specifies the port to connect to on the remote host. Note that this option is written with a capital `P', because -p is already reserved for preserving the times and modes of the file in rcp(1). -S program Name of program to use for the encrypted connection. The program must understand ssh(1) options. -o ssh_option Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no separate scp command-line flag. For example, forcing the use of protocol version 1 is specified using scp -oProtocol=1. -4 Forces scp to use IPv4 addresses only. -6 Forces scp to use IPv6 addresses only.
