# rftp - ftp a directory hierarchy (i.e. recursive ftp)
# Version 2.10
# Don Libes, NIST
exp_version -exit 5.0
# rftp is much like ftp except that the command ~g copies everything in
# the remote current working directory to the local current working
# directory. Similarly ~p copies in the reverse direction. ~l just
# lists the remote directories.
# rftp takes an argument of the host to ftp to. Username and password
# are prompted for. Other ftp options can be set interactively at that
# time. If your local ftp understands .netrc, that is also used.
# ~/.rftprc is sourced after the user has logged in to the remote site
# and other ftp commands may be sent at that time. .rftprc may also be
# used to override the following rftp defaults. The lines should use
# the same syntax as these:
set file_timeout 3600 ;# timeout (seconds) for retrieving files
set timeout 1000000 ;# timeout (seconds) for other ftp dialogue
set default_type binary ;# default type, i.e., ascii, binary, tenex
set binary {} ;# files matching are transferred as binary
set ascii {} ;# as above, but as ascii
set tenex {} ;# as above, but as tenex
# The values of binary, ascii and tenex should be a list of (Tcl) regular
# expressions. For example, the following definitions would force files
# ending in *.Z and *.tar to be transferred as binaries and everything else
# as text.
# set default_type ascii
# set binary {*.Z *.tar}
# If you are on a UNIX machine, you can probably safely ignore all of this
# and transfer everything as "binary".
# The current implementation requires that the source host be able to
# provide directory listings in UNIX format. Hence, you cannot copy
# from a VMS host (although you can copy to it). In fact, there is no
# standard for the output that ftp produces, and thus, ftps that differ
# significantly from the ubiquitous UNIX implementation may not work
# with rftp (at least, not without changing the scanning and parsing).
