NAME

scp - secure copy

SYNOPSIS

scp [OPTION...] [[USER@]HOST1:]FROM_FILE... [[USER@]HOST2:]TO_FILE

DESCRIPTION

scp copies files between the local host and a remote host. File names may contain a user and host specification to indicate that the file is to be copied to/from that host; current user is assumed if the user portion is omitted. Directory copy is done recursively by default. Copying files between remote hosts is not allowed. Copying files on the local host, i.e. both from host and to host are the local host, is not supported. Directory copy is done recursively by default. Copying files between remote hosts is not allowed, and, copying files on the local host is not supported.

scp uses SSH for data transfer, and uses the same authentication and provides the same security as SSH. scp will ask for passphrase if -i option is presented; otherwise, it will ask for password for each distinct user and host specification.

OPTIONS

-H KNOWN_HOSTS_FILE
Set the path to the file that has the identities of all known hosts, default to user-home-directory/.ssh/known_hosts.

-i IDENTITY_FILE
Select the file from which the identity (private key) for RSA authentication is read.

-P PORT
Specify the port to connect to on the remote host, default to 22.

-t
Trust hosts whose identity is unknown.

EXAMPLES

Copy a local file in the working directory to a remote directory:

scp fromFile username@hostname:~/toDirectory

For example, if you want to copy a file named users.csv to a directory called Documents on a remote computer with IP 10.72.5.100 with username aqua enter:

scp users.csv [email protected]:~/Documents

Copy a local file to a remote directory with a different file name:

scp /tmp/fromFile username@hostname:/tmp/newFileName

For example, if you want to copy a file named users.csv and rename it to data.csv enter:
scp users.csv [email protected]:~/Documents/data.csv

Copy local files to a remote directory:

scp /tmp/fromFile1 /tmp/fromFile2 username@hostname:/tmp

For example, if you want to copy all sql file with extension .sql to a remove directory enter:
scp *.sql [email protected]:~/Documents

Copy a local directory to a remote directory, note that the /tmp/dirName directory on the remote machine needs to be created beforehand:

scp /tmp/dirName username@hostname:/tmp/dirName

For example, to copy a local directory named csv to a remote machine enter:

scp /home/tariq/csv [email protected]:~/Documents

Copy a remote file to a local directory:

scp username@hostname:/tmp/fromFile /tmp/toDirectory

For example, to copy a file from a remote host named data.log to the local machine under a folder named temp enter:
scp [email protected]:~/Documents/data.log temp/

Copy a remote directory to a local directory, note that the trailing asterisk after the fromDirectory is required in order for directory copy to work:

scp username@hostname:/tmp/fromDirectory/* /tmp/toDirectory

For example: scp [email protected]:~/Documents/* temp/

Copy a local file in the working directory to a remote directory with a custom identity file use the -i option.

scp -i IDENTITY_FILE fromFile username@hostname:~/toDirectory

For example, if you want to copy a file named users.csv to a directory called Documents on a remote computer with identity file enter the below command. id_rsa is the so called private key when you generate a SSH key public/private key pair.

scp -i /home/tariq/.ssh/id_rsa users.csv [email protected]:~/Documents

NOTES

If the destination to where file(s) to be copied is a directory, then the destination directory needs to be created before the scp command is executed; otherwise, exception will be thrown.
