FAQs on Scp command - SCP to Securely Transfer Files/Folders in Linux Video Lecture - Complete Linux Course: Become a Linux Professional - Software Development
| 1. What is SCP command in Linux and how does it work? |  |
Ans. The SCP command in Linux is used to securely transfer files and folders between different hosts on a network. It uses the SSH protocol to encrypt and transfer the data. SCP works by establishing a secure connection between the source and destination hosts, and then copying the files or folders over this secure connection.
| 2. How do I use SCP to transfer files from a local machine to a remote server? | |
Ans. To transfer files from a local machine to a remote server using SCP, you can use the following command:
```
scp <source file> <username>@<remote host>:<destination directory>
```
Replace `<source file>` with the path or name of the file on your local machine, `<username>` with your remote server username, `<remote host>` with the IP address or hostname of the remote server, and `<destination directory>` with the directory path on the remote server where you want to copy the file.
| 3. Can SCP be used to transfer entire folders instead of just files? | |
Ans. Yes, SCP can be used to transfer entire folders in addition to individual files. To transfer a folder, you can use the following command:
```
scp -r <source folder> <username>@<remote host>:<destination directory>
```
Replace `<source folder>` with the path or name of the folder on your local machine, `<username>` with your remote server username, `<remote host>` with the IP address or hostname of the remote server, and `<destination directory>` with the directory path on the remote server where you want to copy the folder.
| 4. How can I transfer files from a remote server to my local machine using SCP? | |
Ans. To transfer files from a remote server to your local machine using SCP, you can use the following command:
```
scp <username>@<remote host>:<source file> <destination directory>
```
Replace `<username>` with your remote server username, `<remote host>` with the IP address or hostname of the remote server, `<source file>` with the path or name of the file on the remote server, and `<destination directory>` with the directory path on your local machine where you want to copy the file.
| 5. Is it possible to use SCP with a different port number for SSH connection? | |
Ans. Yes, it is possible to use SCP with a different port number for the SSH connection. By default, SCP uses port 22 for the SSH connection. However, you can specify a different port number using the `-P` option followed by the desired port number. For example:
```
scp -P 2222 <source file> <username>@<remote host>:<destination directory>
```
Replace `2222` with the desired port number, `<source file>` with the path or name of the file on your local machine, `<username>` with your remote server username, `<remote host>` with the IP address or hostname of the remote server, and `<destination directory>` with the directory path on the remote server where you want to copy the file.

hey guys in this video I'm going to show
you how you can use SCP command to copy
your files or directories from your
local machine to a remote server or from
your remote server to your local machine
how to use SCP for you know transferring
files I'm going to show you so let's say
I have a remote server on the right-hand
side I have a virtual machine I'm going
to treat it as a remote server so this
on the right hand side is my remote
server and on the left hand side this
one is my local machine let's say and I
want to transfer the file from my local
machine to a remote server first of all
and then I will show you the vice-versa
so first of all let's see what are the
options we have with the SCP command by
the way as CP stands for secure copy and
if you know CP command it's similar to
that so just write SCP on your client
and then press Enter which is going to
show you all the options which you can
use with the SCP so to use SCP you need
to give the username and the host IP and
then your file name for example so let's
say I have a file called hello dot Sh
on my desktop folder so I'm going to
just CD to my desktop first of all and
then I will transfer this hello dot Sh
to the server to the home directory so
this is my home directory and let me
just do LS here which will list out all
the files and directories in my remote
server or in the home folder right so
let's copy this hello dot Sh to the
remote server so we will use a CP
command and the IP of this remote server
so to know the IP of the remote server
you just say if config and then press
enter and this is the IP address of the
remote server right and then we also
need the user
so username in my case is code bind it
can be different in your case right so
first of all your file name so just give
the file name in my case its hello dot
Sh and then the host name which is code
bind in my case it can be different in
your case so this is the username right
and then at the rate the IP address and
then the IP address which is this one so
I'm going to just write 192.168.255.255
so in in whatever folder you want to
transfer your files you just need to
give the path of that so for example I
want to just transfer my files to the
home directory which is home forward
slash code bind I will just write that
here so I'm going to just paste it here
so forward slash home forward slash code
binder okay and then press Enter and for
the first time it will ask you are you
sure you want to continue connecting you
can just say yes for the first time and
then press ENTER and then it's going to
need your remote servers password so the
password you use to log into this remote
server you need to give it here so I'm
going to give the same password here and
then this file is transferred and you
can see this file is now appearing here
also hello dot SH and then when I do LS
here I can see this file once again here
earlier this file was not present here
okay so this is how you can transfer a
file from your host PC to a remote
server now let's say you have multiple
files so you have some directory and
then you want to transfer the content of
that directory so let me just go to my
home directory so I will just do CD and
let me just clear the terminal and let's
say I want to create a directory so I
will just
create a directory called test here or
test123 here and then I will just CD
into that directory CD test one two
three and create some files so I will
just use a touch command to create these
files I'm not going to fill any content
in these files but just the file name so
for example file one dot txt and then
file - dot txt and then file 3 dot dot
txt any number of file you can create
and then I will do LS to list out all
the files right so these are all the
files and I want to transfer these files
with the directory to my remote server
how can I do it so let me just go to my
home folder once again and let me do LS
so let's say I want to just transfer
this directory okay so I will use the
SCP command and then - R for recursive
copying and once again the username so
let me just use the same command which I
used previously
so SCP and then and then - our flag to
copy your files or directory recursively
and then your directory name so for
example to my directory name is test 1 2
3 I want to transfer all the files in
that directory so just give the name of
your directory here ok and let's say I
want to transfer this directory once
again to my home folder of my remote
server so username and then IP address
and then the location where you want to
transfer your directory ok so I will
just press enter once again and give my
password for my remote server once again
and you can see this directory is copied
to my remote server and inside this
directory I have all these three files
this I can verify from my command line
also so test 1 2 3 LS and all these
files are present here also now let's
say I want to transfer or copy files
from my remote server to my host server
till now what we were doing is we were
copying the files from our local machine
to the remote server let's say I want to
do the reverse of that so I want to copy
them the files from the remote server to
my home file so how can I do it so for
doing this let's say what I want to
transfer let's say I want to transfer
this dot de B file right from my remote
server to my local machine so let me
just clear the terminal and let's see
how we can do it so once again you use
the SCP command and this time you use
the username first of all of your remote
server so code bind is the username and
then the IP address of your remote
server so once again I will see the IP
address 192.168.1.1 right and then the
semicolon and then the folder name from
where you want to copy your file so home
forward slash code bind this is the
folder from where I want to copy my file
and the file name itself so I want to
copy this file right so just just write
the file name here itself and then
wherever you want to copy so for example
I want to copy this dot de file from the
remote server to my desktop so how can I
do it so after the space I'm going to
give the destination folder where I want
to copy it so let's say home folder and
then I want to copy it on my desktop so
I will just give the destination folder
name and then press Enter and then gave
the password of my remote PC and then
press ENTER and then it's going to start
copying this file to my local machine
you can see this is already present so
it's giving us the percentage which is
transferred now let's say on your remote
server OpenSSH is running on some
different port
then the default port which is port 22
so let's say it's running on port 1 2 3
4 then how you can you know use that
port so you can just give SCP command
once again to get the help and you can
see with capital P flag you can give the
port name right so last command we have
given here you could have given if the
port is different you could have given
capital P and then port 1 2 3 4 for
example if this open sss server on the
server side on the remote server side
runs on different port
okay so port you can give something like
this if this server has some you know
private key and you want to connect it
using your public key then you can use -
a flag and the path to your public key
here and then you will be able to
connect it ok so if you want to connect
it using your public key you can give -
I flag and then forward slash your keys
path so this is how you can use SCP
command in your Linux operating system I
