Below are two answers  First is a suggestion to use a more secure flexible solution like ssh scp sftp  Second is an explanation of how to run ftp in batch mode  A secure solution  You really should use SSH SCP SFTP for this rather than FTP  SSH SCP have the benefits of being more secure and working with public private keys which allows it to run without a username or password  You can send a single file  scp  lt file to upload gt   lt username gt   lt hostname gt   lt destination path gt   Or a whole directory  scp -r  lt directory to upload gt   lt username gt   lt hostname gt   lt destination path gt   For more details on setting up keys and moving files to the server with RSYNC  which is useful if you have a lot of files to move  or if you sometimes get just one new file among a set of random files  take a look at  http   troy jdmz net rsync index html You can also execute a single command after sshing into a server  From man ssh  ssh     snipped     hostname  command  If command is specified  it is executed on the remote host instead of a login shell   So  an example command is  ssh username hostname example bunzip file just sent bz2  If you can use SFTP with keys to gain the benefit of a secured connection  there are two tricks I ve used to execute commands  First  you can pass commands using echo and pipe echo  quot put files  xml quot    sftp -p -i    ssh key name username hostname example  You can also use a batchfile with the -b parameter  sftp -b batchfile txt    ssh key name username hostname example  An FTP solution  if you really need it  If you understand that FTP is insecure and more limited and you really really want to script it    There s a great article on this at http   www stratigery com scripting ftp html    bin sh HOST  ftp example com  USER  yourid  PASSWD  yourpw  FILE  file txt   ftp -n  HOST  lt  lt END SCRIPT quote USER  USER quote PASS  PASSWD binary put  FILE quit END SCRIPT exit 0  The -n to ftp ensures that the command won t try to get the password from the current terminal  The other fancy part is the use of a heredoc  the  lt  lt END SCRIPT starts the heredoc and then that exact same END SCRIPT on the beginning of the line by itself ends the heredoc  The binary command will set it to binary mode which helps if you are transferring something other than a text file

You can use a heredoc to do this e g   ftp -n  Server  lt  lt End-Of-Session   -n option disables auto-logon  user anonymous   Password  binary cd  Directory put   Filename lsm  put   Filename tar gz  bye End-Of-Session   so the ftp process is fed on stdin with everything up to End-Of-Session  A useful tip for spawning any process  not just ftp  Note that this saves spawning a separate process  echo  cat etc    Not a major resource saving  but worth bearing in mind

The ftp command isn t designed for scripts  so controlling it is awkward  and getting its exit status is even more awkward   Curl is made to be scriptable  and also has the merit that you can easily switch to other protocols later by just modifying the URL  If you put your FTP credentials in your  netrc  you can simply do     Download file curl --netrc --remote-name ftp   ftp example com file bin   Upload file curl --netrc --upload-file file bin ftp   ftp example com    If you must  you can specify username and password directly on the command line using --user username password instead of --netrc

No need to complicate stuff - this should work     bin bash echo    verbose  open ftp mydomain net  user myusername mypassword  ascii  put textfile1  put textfile2  bin  put binaryfile1  put binaryfile2  bye     ftp -n  gt  ftp    log   or you can use mput if you have many files
