Here's the NETRC file:

:print netrc.pub
machine "remsys.hp.com" login "jeff.vance" password "uPass,aPass"
default login "mgr.sys" password "u1,a1"

:sftpput catalog.pub.sys, remsys.cup.hp.com  <-- note no username

   --- SFTPPUT ---   version A.06

++ Note: _SFTP_DEBUG=TRUE so all temporary files and variables
   used by the script are preserved, and more verbose messages
   are displayed. To see the script variables enter :showvar
   _ftp_@. To see the temp files enter :listfile ./@;temp
   To disable this feature :deletevar _sftp_debug, or set this
   variable to FALSE.

++ Note: NETRC file in effect
++ Note: No 'remoteuser' parm supplied so "JEFF.VANCE" is assumed
   to be the remote MPE logon user.acct. If this is not the same
   login user id found in the NETRC file, then the MPE job to
   decrypt the file(s) will logon as a different user (or the
   logon could fail), and could logon to a different group, and
   thus may not find the encrypted file(s). When using NETRC it's
   better to supply the NETRC machine user as the 'remoteuser'
   parm (parm 3) here.
