The FTP (file transfer program) utility is used to transfer
files between a local machine and remote network machine Using the File
Transfer protocol. In simple terms it transfers / copies files between two
computers. You can transfer files between unix systems and also non-unix
systems like windows operating system using FTP.
The FTP command is simple to use and easy to learn. Let see useful examples of FTP command in detail.
FTP Command Examples:
If you are using windows operating system, open the command prompt and practice the below FTP commands. If you are using unix or linux operating systems, just simply type the ftp command on the terminal.

The FTP command is simple to use and easy to learn. Let see useful examples of FTP command in detail.
FTP Command Examples:
If you are using windows operating system, open the command prompt and practice the below FTP commands. If you are using unix or linux operating systems, just simply type the ftp command on the terminal.
1. Connecting to Remote Host
First you need to connect to a remote host before doing any operations. You can use any one of the following methods to connect to a remote host. First method is
>
ftp remote-server-name
connected
to remote-server-name
User-Name:
Password:
ftp>
Once the ftp connects to the remote server name, it will prompt you to enter the user name and password. After successful login, your terminal or prompt changes to "ftp>".
Another method is to use the open option with ftp command. This is shown below:
>ftp
ftp>open
remote-server-name
connected
to remote-server-name
User-Name:
Password:
ftp>
If the ftp command fails to connect to the remote server, then you will get the below error:
ftp:
connect: Connection refused
2. Copy file from remote machine to local machine.
The get option is used to download or transfer a file from the remote system to the local system.
ftp>
get windows-cleveland.bat
This will download the specified file (windows-cleveland.bat) from the remote systems current directory.
3. Copying multiple files from remote machine to local machine.
You can use the get to transfer multiple files from the remote host to local host.
ftp>get
*.png
This will download all the png images to the local machine.
4. Transferring file from local server to remote server
The put option is used to copy the file from the local host to the remote host.
ftp>put
linux-virtual-server.rpm
This command puts the rpm file into the remote machine.
5. Transferring multiple files to the remote server.
You can use the put option to transfer more than one file from local system to the remote system.
ftp>put
*.rpm
6. Executing commands in remote machine.
After connecting to the remote network machine using the ftp, you can run commands like ls to list the files, cd to change directory and many more.
ftp>
ls
This will list the files and directories in the remote machines current directory.
7. Executing commands in local machine.
Once you have connected to the remote host, to run the commands on local machine you need to exit from the ftp connection. Instead of this, there is a way to run commands on local host without exiting from the ftp connection. Use the ! Symbol before the command you want to run.
ftp>
!ls
Now this will list the files in the local machines current directory.
8. Changing the file transferring mode.
You can change the file transfer modes to ascii and binary modes. Use the below commands to change the mode.
ftp>ascii
ftp>binary
9. Deleting files on remote machine
You can use the delete or mdelete to remove a single file or multiple files in the remote machine.
ftp>delete
linux-dedicated-server.dat
ftp>mdelete
*.dat
10. Disconnecting from ftp connection.
Use the quit command to close the ftp connection.
ftp>quit
11. Using FTP command in batch scripts
The following script reads the instructions from the dat file and executes them on the remote machine.
echo
"Ftp command batch script"
echo
"start"
ftp
-s:instructions.dat remote-host
echo
"End"
The contents of the instructions.dat file is
user
password
cd
/var/tmp
put
oracle_storage.exe
quit
