to use sftp you have to download/install a sftp client which you can get from openssh suit , ( openssh.org  )

to start using sftp instead of ftp you just have to install sftp client and

instead of doing a
  ftp hostname

you do a

sftp hostname

i.e in all scripts/programs you have you just need to change all 'ftp' to 'sftp'

If you script ftp via expect or so - note that sftp may not have mget, and always uses full command , i.e get, and not g, quit and not qui etc...

There's a lot of differences between FTP and SFTP behind the covers, however from a end user point of view, there's very little difference in how they work, with the exception of automating scripts.

With FTP you can use .netrc files which SFTP doesn't support (AFAIK) and with SFTP you can use keys to automate logins.

Just add a bit more infor.

the plain text FTP shipped with *nix by default, sftp is third party package (normally
comes with secure shell), and the sys adm have to install it on the system (most
of the *nix system have them install, to use sftp client, the secure shell server (sshd)
have to running on the sftp server.

I'm not sure this piece of trivia has been mentioned, but... Although the name sftp in some ways imply a relationship with ftp, there really are none (other than similarities in the command interface, and that both are used to transfer files). Sftp is actually implemented through scp (the rcp replacement of the ssh suite). That is, sftp is more like a wrapper around scp. So in an automation script it'd often make more sense to use scp directly.
