Using a UNIX FTP Client to Transfer Files between Mainframe Computers

Using a UNIX FTP Client to Transfer Files between Mainframe Computers

Starting FTP:
1. Log onto an account on one of the mainframe computers. This computer is referred to as the local host. The computer to or from which you copy files is known as the remote host.
2. Issue the UNIX FTP command to contact the remote host:
```
          ftp remote-host-name
```
  where remote-host-name is the full address of the remote computer (e.g., gis.smith.udel.edu).
3. When the connection to the remote host is made, you receive a message of the form:
```
          Connected to gis.smith.udel.edu.
          220 gis.smith.udel.edu FTP server (UNIX(r) System V Release 4.0) ready.
          Name (gis.smith.udel.edu:username):
```
  where username is your username on the local host, the system on which you initiated the FTP session.
4. Identify yourself to the remote host:
  - Type your username for the remote host and press ENTER:
```
          Name (gis.smith.udel.edu:local-username): remote-username
```
    (If your username on the remote host is the same as on your local host, just press ENTER.)
    At the next prompt, type your password and press ENTER. Your password does not appear on the screen.
Transferring files:
1. Set the type of file(s) you are to transfer:
  - for files that contain only text or program source code, use the command
```
          ascii
```
  - for files that contain executable programs or files with formatting codes such as those produced by word processing, spreadsheet or graphics programs, use the command
```
          binary
```
2. To transfer any file(s), you must indentify the current location or destination of the file(s) on the both the local and remote hosts. Use the cd command to change remote directories and lcd to change directories on the local host. For example, to set the remote directory to consult/project1 and the local directory to sas:
```
          cd consult
          cd project1
          lcd sas
```
Transferring file(s) from the remote host to your local host:
1. Specify one file (e.g., anova.sas) to "get" from the remote host:
```
          get anova.sas
```
2. Specify all files that have a certain pattern (e.g., those that end with .dat) using the mget command and wildcards:
```
          mget *.dat
```
3. If you have selected just one file, you can give it a new name on your local host. For example, to copy the file anova.sas from the remote host to your local host with the name newanova.sas:
```
          get anova.sas newanova.sas
```
Transferring file(s) from your local host to the remote host:
1. Specify one file (e.g., bizeval.dat) to "put" on the remote host:
```
          put bizeval.dat
```
2. Specify all files that have a certain pattern (e.g., those that begin with eval2) using the mput command and wildcards:
```
          mput eval2.*
```
3. If you have selected just one file, you can give it a new name on the remote host. For example, to copy the file bizeval.dat from your local host to the remote host with the name newbizeval.dat:
```
          put bizeval.dat newbizeval.dat
```
Closing FTP:
To close the connection with the remote host, use the command:
```
          quit
```
